If the EEPROM is set to read mode during the internal programming cycle, I/O6 will charge from "1" to "0" (toggling) for each read. When the internal programming cycle is finished, toggling of I/O6 will stop and the device can be accessible for next read or program. Toggle bit Waveform Notes: 1. I/O6 beginning state is "1". 2.

Following the initial byte cycle, an additional 1 to 63 bytes can be written in the same manner. Each additional byte load cycle must be started within 30 s from the preceding falling edge of WE or CE. When CE or WE is high for 100 s after data input, the EEPROM enters write mode automatically and the input data are written into the EEPROM. Data Polling Data polling indicates the status that the EEPROM is in a write cycle or not. If EEPROM is set to read mode during a write cycle, an inversion of the last byte of data outputs from I/O7 to indicate that the EEPROM is performing a write operation. RDY/Busy Busy Signal (only the HN58V257A series) RDY/Busy signal also allows the status of the EEPROM to be determined. The RDY/Busy signal has high impedance except in write cycle and is lowered to VOL after the first write signal. At the end of a write cycle, the RDY/Busy signal changes state to high impedance. RES Signal (only the HN58V257A series) When RES is low, the EEPROM cannot be read or programmed. Therefore, data can be protected by keeping RES low when VCC is switched. RES should be high during read and programming because it doesn't provide a latch function.

Write/Erase Endurance and Data Retention Time 5 4 The endurance is 10 cycles in case of the page programming and 10 cycles in case of the byte programming (1% cumulative failure rate). The data retention time is more than 10 years when a device is page4 programmed less than 10 cycles. Data Protection To prevent this phenomenon, this device has a noise cancellation function that cuts noise if its width is 20 ns or less. 1. Data Protection against Noise on Control Pins (CE, OE, WE) during Operation During readout or standby, noise on the control pins may act as a trigger and turn the EEPROM to programming mode by mistake. Be careful not to allow noise of a width of more than 20 ns on the control pins. WE CE VIH 0V VIH OE 0V 20 ns max Rev.5.00, Nov. 17.2003, page 17 of 22 HN58V256A Series, HN58V257A Series 2. Data Protection at VCC On/Off When VCC is turned on or off, noise on the control pins generated by external circuits (CPU, etc) may act as a trigger and turn the EEPROM to program mode by mistake. To prevent this unintentional programming, the EEPROM must be kept in an unprogrammable state while the CPU is in an unstable state. Note: The EPROM should be kept in unprogrammable state during VCC on/off by using CPU RESET signal. VCC CPU RESET * Unprogrammable * Unprogrammable 2.1 Protection by CE, OE, WE To realize the unprogrammable state, the input level of control pins must be held as shown in the table below. CE VCC x x OE x VSS x WE x x VCC x: Don't care. VCC: Pull-up to VCC level. VSS: Pull-down to VSS level. 2.2 Protection by RES (only the HN58V257A series) The unprogrammable state can be realized by that the CPU's reset signal inputs directly to the EEPROM's RES pin. RES should be kept VSS level during VCC on/off. The EEPROM breaks off programming operation when RES becomes low, programming operation doesn't finish correctly in case that RES falls low during programming operation. RES should be kept high for 10 ms after the last data input.

Software data protection To prevent unintentional programming, this device has the software data protection (SDP) mode. The SDP is enabled by inputting the following 3 bytes code and write data. SDP is not enabled if only the 3 bytes code is input. To program data in the SDP enable mode, 3 bytes code must be input before write data. Address Data 5555 AA 2AAA 55 5555 A0 Write address Write data } Normal data input The SDP mode is disabled by inputting the following 6 bytes code. Note that, if data is input in the SDP disable cycle, data can not be written. Address Data 5555 2AAA 5555 5555 2AAA 5555 AA 55 80 AA 55 20 The software data protection is not enabled at the shipment. Note: There are some differences between Renesas Technology's and other company's for enable/disable sequence of software data protection.
