Microchip ??s 25AA256/25LC256 family of devices are 256 Kbit SPI Serial EEPROMs available in a variety of package, temperature and power supply variants. The Serial Peripheral Interface (SPI) is utilised to provide the required Clock Input (SCK), Data In (SI) and Data Out (SO) signals. The operation of these devices can be paused via a Hold pin (HOLD) which causes inputs to be ignored with the exception higher priority interrupts defined via the Chip Select (CS) pin. Features. Max. Clock 10 MHz Maximum write current 5 mA Read current: 6 mA (typical) Standby current: 1 μA (typical) 32,768 x 8-bit Organization 64-Byte Page Self-Timed Erase and Write Cycles, 5 ms (maximum) Block Write Protection: Protect none, 1/4, 1/2 or all of array Built-In Write Protection: Power-on/off data protection circuitry, Write enable latch, Write-protect pin Sequential Read Endurance: >1M erase/write cycles Data retention: >200 years ESD protection: >4000V
