Product details
25AA256/25LC256 SPI Serial EEPROM
Microchips 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
