| Part Number | FM25C640U |
| Manufacturer | Fairchild Semiconductor |
| Description | The FM25C640U is a 64K bit serial interface CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory). This device fully conforms to the SPI 4-wire protocol which uses Chip Select (/CS), Clock... |
| Features |
I Sequential read of entire array I 32 byte "Page write" mode to minimize total write time per byte I /WP pin and BLOCK WRITE protection to prevent inadvertent programming as well as programming ENABLE and DISABLE opcodes. I /HOLD pin to suspend data transfer I Typical 1µA standby current (ISB) for "L" devices and 0.1µA standby current for "LZ" devices. I Endurance: Up to 1,000,000 data changes I Data retention greater than 40 years
