Sync data input / output timing Data is taken by DI sync with the rise of SK. At read action, data is output from DO in sync with the rise of SK. The STATUS signal at write (READY / BUSY) is output after tCS from the fall of CS after write command input, at the area DO where CS is "H", and valid until the next command start bit is input. And, while CS is "L", DO becomes High-Z. After completion of each mode execution, set CS "L" once for internal circuit reset, and execute the following action mode. 1/fSK is the SK clock cycle, even if fSK is maximum, the SK clock cycle can't be tSKH(Min.)+tSKL(Min.)

When to connect one EEPROM to a microcontroller, connect it as shown in Figure 34(a) or Figure 34(b). When to use the input and output common I/O port of the microcontroller, connect DI and DO via a resistor as shown in Figure 34(b) (Refer to pages 21, 22.), and connection by 3 lines is available. In the case of plural connections, refer to Figure 34 (c). Microcontroller SK SK SK DO DI DI DO BR93GXX CS SK DI/O DI DO (a). Connection by 4 lines CS3 CS2 CS1 SK DO DI (b).

Connection method with microcontroller Communications of the MicroWire BUS are started by the first "1" input after the rise of CS. This input is called a start bit. After input of the start bit, input ope code, address and data. Address and data are input all in MSB first manners. "0" input after the rise of CS to the start bit input is all ignored. Therefore, when there is limitation in the bit width of PIO of the microcontroller, input "0" before the start bit input, to control the bit width. Command mode Command Read (READ) *1 Start bit Ope code Address BR93G66-3 MSB of Address(Am) is A7 Data MSB of Data(Dx) is D15 A7,A6,A5,A4,A3,A2,A1,A0 D15~D0(READ DATA) 1 10 Write enable (WEN) 1 00 1 1 ****** Write disable (WDS) 1 00 0 0 ****** Write (WRITE) *2 1 01 1 00 Erase (ERASE) 1 11 Erase all (ERAL) 1 00 Write all (WRAL) *2 A7,A6,A5,A4,A3,A2,A1,A0 0 1 ****** A7,A6,A5,A4,A3,A2,A1,A0 1 0 ****** Required clocks(n) BR93G66-3:n=27 BR93G66-3:n=11 D15~D0(WRITE DATA) D15~D0(WRITE DATA) BR93G66-3:n=27 BR93G66-3:n=11 Input the address and the data in MSB first manners. As for *, input either "1" or "0" . *Start bit Acceptance of all the commands of this IC starts at recognition of the start bit. The start bit means the first "1" input after the rise of CS. *1 *2 As for read, by continuous SK clock input after setting the read command, data output of the set address starts, and address data in significant order are sequentially output continuously. (Auto increment function) For write or write all commands, a internal erase or erase all is included and no separate erase or erase all is needed before write or write all command. www.rohm.com (c) 2012 ROHM Co., Ltd.

And when "1" is input after plural "0" are input, it is recognized as a start bit, and the following operation is started. This is common to all the commands to described hereafter. *2 For the meaning of Am,Dx,n,please see tables of command mode in Page15. For example, Am=A7,Dx=D15,n=27. Figure 35. Read cycle When the read command is recognized, input address data (16bit) is output to serial. And at that moment, at taking A0, in sync with the rise of SK, "0" (dummy bit) is output. And, the following data is output in sync with the rise of SK. This IC has an address auto increment function which is valid only at read command. This is the function where after the above read execution, by continuously inputting SK clock, the above address data is read sequentially. And, during the auto increment, keep CS at "H". 2) Write cycle (WRITE) tCS CS A1 A0 Dx Dx-1 D1 D0 Am 1 0 1 n 4 DI 2 1 SK STATUS Am: MSB of address Dx: MSB of data n: required clocks tSV BUSY READY DO High-Z For the meaning of Am,Dx,n, please see tables of command mode in Page15. tE/W Figure 36. Write cycle In this command, input 16bit data are written to designated addresses (Am~A0). The actual write starts by the fall of CS of D0 taken SK clock. When STATUS is not detected (CS="L" fixed),make sure Max 5ms time is in comforming with tE/W. When STATUS is detected (CS="H"), all commands are not accepted for areas where "L" (BUSY) is output from D0, therefore, do not input any command. 3) Write all cycyle (WRAL) tCS CS 1 Dx Dx-1 D1 D0 Dx: MSB of data n: required clocks 0 0 0 1 DI n 5 2 1 SK STATUS tSV BUSY READY DO High-Z For the meaning of Dx,n,please see tables of command mode in Page15. tE/W Figure 37.

Figure 38. Write enable (WEN) / disable (WDS) cycle At power on, this IC is in write disable status by the internal RESET circuit. Before executing the write command, it is necessary to execute the write enable command. And, once this command is executed, it is valid unitl the write disable command is executed or the power is turned off. However, the read command is valid irrespective of write enable / diable command. Input to SK after 6 clocks of this command is available by either "1" or "0", but be sure to input it. When the write enable command is executed after power on, write enable status gets in. When the write disable command is executed then, the IC gets in write disable status as same as at power on, and then the write command is canceled thereafter in software manner. However, the read command is executable. In write enable status, even when the write command is input by mistake, write is started. To prevent such a mistake, it is recommended to execute the write disable command after completion of write. 5) Erase cycle (ERASE) STATUS Am A3 A2 A1 A0 1 1 tSV BUSY READY DO Am: MSB of address n: required clocks 1 DI n 4 2 1 SK tCS CS High-Z tE/W For the meaning of Am,n,please see tables of command mode in Page15.

By making CS="L" at power ON/OFF, mistake in operation and mistake write are prevented. Pull down resistance Rcs of CS pin To prevent mistake in operation and mistake write at power ON/OFF, CS pull down resistance is necessary.

Do output always is "High-Z" except in READY / BUSY STATUS and data output in read command. Malfunction may occur when "High-Z" is input to the microcontroller port connected to DO, it is necessary to pull down and pull up DO. When there is no influence upon the microcontroller actions, DO may be OPEN. If DO is OPEN, and at timing to output STATUS READY, at timing of CS="H", SK="H", DI="H", EEPROM recognizes this as a start bit, resets READY output, and DO="High-Z", therefore, READY signal cannot be detected.

When CS is started after tCS from CS fall after write command input, "H" or "L" is output. R/B display"L" (BUSY) = write under execution After the timer circuit in the IC works and creates the period of tE/W, this timer circuit completes automatically. And the memory cell is written in the period of tE/W, and during this period, other command is not accepted.

Therefore, CS="H" in the period of tE/W, and If signals are input in SK, DI, malfunction may occur, therefore, DI="L" in the area CS="H". (Especially, in the case of shared input port, attention is required.) DO STATUS *Do not input any command while STATUS signal is output.

When the next start bit input is recognized, "HIGH-Z" gets in. Especially, at command input after write, when CS input is started with microcontroller DI/O output "L", READY output "H" is output from DO terminal, and through current route occurs.

When through current flows, noises of power source line and instantaneous stop of power source may occur. When allowable through current is defined as I, the following relation should be satisfied. Determine allowable current amount in consideration of impedance and so forth of power source line in set.

If power is turned on in this status, noises and the likes may cause malfunction, mistake write or so. To prevent these, at power ON, set CS "L". (When CS is in "L" status all inputs are cancelled.) And at power decline, owing to power line capacity and so forth, low power status may continue long. At this case too, owing to the same reason, malfunction, mistake write may occur, therefore, at power OFF too, set CS "L". VCC VCC GND VCC CS GND Bad example Good example Figure 59. Timing at power ON/OFF Bad exampleCS pin is pulled up to VCC Good exampleIt is "L" at power ON/OFF. In this case, CS becomes "H" (active status), and EEPROM may have malfunction, mistake write owing to noise and the likes. Even when CS input is High-Z, the status becomes like this case, which please note. Set 10ms or higher to recharge at power OFF. When power is turned on without observing this condition, IC internal circuit may not be reset, which please note. POR citcuit This IC has a POR (Power On Reset) circuit as a mistake write countermeasure. After POR action, it gets in write disable status. The POR circuit is valid only when power is ON, and does not work when power is OFF. However, if CS is "H" at power ON/OFF, it may become write enable status owing to noises and the likes. For secure actions, observe the follwing conditions. 1. Set CS="L" 2. Turn on power so as to satisfy the recommended conditions of tR, tOFF, Vbot for POR circuit action.

SK noise When the rise time of SK is long, and a certain degree or more of noise exists, malfunction may occur owing to clock bit displacement. To avoid this, a Schmitt trigger circuit is built in SK input. The hysteresis width of this circuit is set about 0.2V, if noises exist at SK input, set the noise amplitude 0.2Vp-p or below. And it is recommended to set the rise time of SK 100ns or below. In the case when the rise time is 100ns or higher, take sufficient noise countermeasures. Make the clock rise, fall time as small as possible. www.rohm.com (c) 2012 ROHM Co., Ltd. All rights reserved.

(2) We believe that application circuit examples are recommendable, however, in actual use, confirm characteristics further sufficiently. In the case of use by changing the fixed number of external parts, make your decision with sufficient margin in consideration of static characteristics and transition characteristics and fluctuations of external parts and our LSI. (3) Absolute Maximum Ratings If the absolute maximum ratings such as impressed voltage and action temperature range and so forth are exceeded, LSI may be destructed. Do not impress voltage and temperature exceeding the absolute maximum ratings. In the case of fear exceeding the absolute maximum ratings, take physical safety countermeasures such as fuses, and see to it that conditions exceeding the absolute maximum ratings should not be impressed to LSI. (4) GND electric potential Set the voltage of GND terminal lowest at any action condition. Make sure that each terminal voltage is not lower than that of GND terminal in consideration of transition status. (5) Heat design In consideration of allowable loss in actual use condition, carry out heat design with sufficient margin. (6) Terminal to terminal short circuit and wrong packaging When to package LSI onto a board, pay sufficient attention to LSI direction and displacement. Wrong packaging may destruct LSI. And in the case of pin short between LSI terminals and terminals, terminals and power source, terminals and GND owing to unconnect use, LSI may be destructed. (7) Using this LSI in a strong electromagnetic field may cause malfunction, therefore, evaluate the design sufficiently.

Precaution on using ROHM Products 1) Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment, OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you intend to use our Products in devices requiring extremely high reliability (such as medical equipment, transport equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or serious damage to property ("Specific Applications"), please consult with the ROHM sales representative in advance. Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties arising from the use of any ROHM's Products for Specific Applications. 2) ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which a failure or malfunction of our Products may cause. The following are examples of safety measures: [a] Installation of protection circuits or other protective devices to improve system safety [b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure 3) Our Products are designed and manufactured for use under standard conditions and not under any special or extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way responsible or liable for any damages, expenses or losses arising from the use of any ROHM's Products under any special or extraordinary environments or conditions. If you intend to use our Products under any special or extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: [a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents [b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust [c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2 [d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves [e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items [f] Sealing or coating our Products with resin or other coating materials [g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning residue after soldering [h] Use of the Products in places subject to dew condensation 4) The Products are not subject to radiation-proof design. 5) Please verify and confirm characteristics of the final or mounted products in using the Products. 6) In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse) is applied, confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability. 7) De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual ambient temperature. 8) Confirm that operation temperature is within the specified range described in the product specification. 9) ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in this document.
