Microchip 25LC256-I/ST are 256 Kbit Serial Electrically Erasable PROMs. The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD).
Max. Clock 10 MHz
Low-Power CMOS Technology: Max. Write Current: 5 mA at 5.5V, 10 MHz, Read Current: 6 mA at 5.5V, 10 MHz, Standby Current: 1 μA at 5.5V
Self-Timed Erase and Write Cycles (5 ms max.)
Built-In Write Protection: Power-on/off data protection circuitry, Write enable latch, Write-protect pin
Sequential Read
High Reliability: Endurance: 1,000,000 erase/write cycles, Data retention: > 200 years, ESD protection: > 4000V
Temperature Ranges Supported:
RoHS Compliant: Industrial (I): -40°C to +85C, Extended (E): -40°C to +125°C
Automotive AEC-Q100 Qualified
