SYMBOL DESCRIPTION A0-A16 Address Inputs Chip Enable (CE) I/O0-I/O7 Data Input/Output WE Write Enable CE Chip Enable OE Output Enable VCC +5V VSS Ground NC No Connect VBB* -3V The Chip Enable input must be LOW to enable all read/write operations. When CE is HIGH, power consumption is reduced. Output Enable (OE) The Output Enable input controls the data output buffers, and is used to initiate read operations. Data In/Data Out (I/O0-I/O7) Data is written to or read from the X28C010/X28HT010 through the I/O pins. *VBB applies to X28HT010 only. Write Enable (WE) Device Operation The Write Enable input controls the writing of data to the X28C010/X28HT010. Read Back Bias Voltage (VBB) (X28HT010 only) It is required to provide -3V on pin 1. This negative voltage improves higher temperature functionality. Read operations are initiated by both OE and CE LOW. The read operation is terminated by either CE or OE returning HIGH. This two line control architecture eliminates bus contention in a system environment. The data bus will be in a high impedance state when either OE or CE is HIGH. Write Write operations are initiated when both CE and WE are LOW and OE is HIGH. The X28C010/X28HT010 supports both a CE and WE controlled write cycle. That is, the address is latched by the falling edge of either CE or WE, whichever occurs last. Similarly, the data is latched internally by the rising edge of either CE or WE, whichever occurs first. A byte write operation, once initiated, will automatically continue to completion, typically within 5ms. 3 FN8105.1 February 12, 2007 X28C010, X28HT010 Page Write Operation The page write feature of the X28C010/X28HT010 allows the entire memory to be written in 5 seconds. Page write allows two to two hundred fifty-six bytes of data to be consecutively written to the X28C010/X28HT010 prior to the commencement of the internal programming cycle. The host can fetch data from another device within the system during a page write operation (change the source address), but the page address (A8 through A16) for each subsequent valid write cycle to the part during this operation must be the same as the initial page address. DATA Polling (I/O7) The page write mode can be initiated during any write operation. Following the initial byte write cycle, the host can write an additional one to two hundred fifty six bytes in the same manner as the first byte was written. Each successive byte load cycle, started by the WE HIGH to LOW transition, must begin within 100s of the falling edge of the preceding WE. If a subsequent WE HIGH to LOW transition is not detected within 100s, the internal automatic programming cycle will commence. There is no page write window limitation. Effectively the page write window is infinitely wide, so long as the host continues to access the device within the byte load cycle time of 100s. The X28C010/X28HT010 features DATA Polling as a method to indicate to the host system that the byte write or page write cycle has completed. DATA Polling allows a simple bit test operation to determine the status of the X28C010/X28HT010, eliminating additional interrupt inputs or external hardware. During the internal programming cycle, any attempt to read the last byte written will produce the complement of that data on I/O7 (i.e., write data = 0xxx xxxx, read data = 1xxx xxxx). Once the programming cycle is complete, I/O7 will reflect true data. Note: If the X28C010/X28HT010 is in the protected state, and an illegal write operation is attempted, DATA Polling will not operate. Write Operation Status Bits Toggle Bit (I/O6) The X28C010/X28HT010 provides the user two write operation status bits. These can be used to optimize a system write cycle time. The status bits are mapped onto the I/O bus as shown in Figure 1. The X28C010/X28HT010 also provides another method for determining when the internal write cycle is complete. During the internal programming cycle, I/O6 will toggle from HIGH to LOW and LOW to HIGH on subsequent attempts to read the device. When the internal cycle is complete the toggling will cease and the device will be accessible for additional read or write operations. I/O DP TB 5 4 3 2 1 0 Reserved Toggle Bit DATA Polling FIGURE 1.

The X28C010/X28HT010 is shipped from Intersil with the software data protection NOT ENABLED: that is the device will be in the standard operating mode. In this mode data should be protected during power-up/-down operations through the use of external circuits. The host would then have open read and write access of the device once VCC was stable. Last Write Load Accum From Addr N Compare Accum with Addr N No Compare Ok? The X28C010/X28HT010 can be automatically protected during power-up and power-down without the need for external circuits by employing the software data protection feature. The internal software data protection circuit is enabled after the first write operation utilizing the software algorithm. This circuit is nonvolatile and will remain set for the life of the device unless the reset command is issued. Once the software protection is enabled, the X28C010/X28HT010 is also protected from inadvertent and accidental writes in the powered-up state. That is, the software algorithm must be issued prior to writing additional data to the device. Yes Ready FIGURE 5. TOGGLE BIT SOFTWARE FLOW The Toggle Bit can eliminate the software housekeeping chore of saving and fetching the last address and data written to a device in order to implement DATA Polling. This can be especially helpful in an array comprised of multiple X28C010/X28HT010 memories that is frequently updated. Toggle Bit Polling can also provide a method for status checking in multiprocessor applications. The timing diagram in Figure 4 illustrates the sequence of events on the bus. The software flow diagram in Figure 5 illustrates a method for polling the Toggle Bit. Software Algorithm Selecting the software data protection mode requires the host system to precede data write operations by a series of three write operations to three specific addresses. Refer to Figures 6 and 7 for the sequence. The three byte sequence opens the page write window enabling the host to write from one to two hundred fifty-six bytes of data. Once the page load cycle has been completed, the device will automatically be returned to the data protected state. Hardware Data Protection The X28C010/X28HT010 provides three hardware features that protect nonvolatile data from inadvertent writes. * Noise Protection--A WE pulse less than 10ns will not initiate a write cycle. * Default VCC Sense--All functions are inhibited when VCC is 3.5V. * Write inhibit--Holding either OE LOW, WE HIGH, or CE HIGH will prevent an inadvertent write cycle during powerup and power-down, maintaining data integrity. 6 FN8105.1 February 12, 2007 X28C010, X28HT010 Software Data Protection VCC (VCC) 0V Data Addr AA 5555 55 2AAA A0 5555 Writes Ok CE tBLC MAX WE tWC Write Protected Byte or Page FIGURE 6. TIMING SEQUENCE--BYTE OR PAGE WRITE Regardless of whether the device has previously been protected or not, once the software data protection algorithm is used and data has been written, the X28C010/X28HT010 will automatically disable further writes unless another command is issued to cancel it. If no further commands are issued the X28C010/X28HT010 will be write protected during power-down and after any subsequent power-up.

SOFTWARE SEQUENCE TO DEACTIVATE SOFTWARE DATA PROTECTION In the event the user wants to deactivate the software data protection feature for testing or reprogramming in an EEPROM programmer, the following six step algorithm will reset the internal protection circuit. After tWC, the X28C010/X28HT010 will be in standard operating mode. Because the X28C010/X28HT010 is frequently used in large memory arrays, it is provided with a two line control architecture for both read and write operations. Proper usage can provide the lowest possible power dissipation and eliminate the possibility of contention where multiple I/O pins share the same bus. To gain the most benefit, it is recommended that CE be decoded from the address bus and be used as the primary device selection input. Both OE and WE would then be common among all devices in the array. For a read operation this assures that all deselected devices are in their standby mode and that only the selected device(s) is outputting data on the bus. Because the X28C010/X28HT010 has two power modes, standby and active, proper decoupling of the memory array is of prime concern. Enabling CE will cause transient current spikes. The magnitude of these spikes is dependent on the output capacitive loading of the I/Os. Therefore, the larger the array sharing a common bus, the larger the transient spikes. The voltage peaks associated with the current transients can be suppressed by the proper selection and placement of decoupling capacitors. As a minimum, it is recommended that a 0.1F high frequency ceramic capacitor be used between VCC and VSS at each device. Depending on the size of the array, the value of the capacitor may have to be larger. In addition, it is recommended that a 4.7F electrolytic bulk capacitor be placed between VCC and VSS for each eight devices employed in the array. This bulk capacitor is employed to overcome the voltage droop caused by the inductive effects of the PC board traces. Note: Once initiated, the sequence of write operations should not be interrupted. 8 FN8105.1 February 12, 2007 X28C010, X28HT010 Active Supply Current vs. Ambient Temperature 18 VCC = 5V ICC WR (mA) 16 14 12 10 -55 +35 -10 +80 +125 Ambient Temperature (C) Standby Supply Current vs. Ambient Temperature 0.3 VCC = 5V ISB (mA) 0.25 0.2 0.15 0.1 0.05 -55 +35 -10 +80 +125 Ambient Temperature (C) ICC (RD) by Temperature Over Frequency 60 5.0 VCC ICC RD (mA) 50 -55C +25C 40 +125C 30 20 10 0 3 6 9 12 15 Frequency (MHz) 9 FN8105.1 February 12, 2007 X28C010, X28HT010 Absolute Maximum Ratings Recommended Operating Conditions Temperature under bias X28C010 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .-10C to +85C X28C010I . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .-65C to +135C X28C010M . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .-65C to +135C X28HT010 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .-55C to +175C Storage temperature . . . . . . . . . . . . . . . . . . . . . . . .-65C to +150C Voltage on any pin with respect to VSS . . . . . . . . . . . . . . -1V to +7V D.C. output current. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5mA Lead temperature (soldering, 10 seconds) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +300C Commercial . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0C to +70C Industrial . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .-40C tp +85C Military . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .-55C to +125C Supply Voltage. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .5V 10% High Temperature . . . . . . . . . . . . . . . . . . . . . . . . . .-40C to +175C CAUTION: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
