ATMEL AT25256B-SSHL-T EEPROM, 256 Kbit, 32K x 8位, 20 MHz, SPI, SOIC, 8 引脚
The is a 256kB standard SPI Serial EPPROM provides 131,072/262,144 bits of serial electrically erasable programmable read-only memory EEPROM organized as 16,384/32,768 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT25256B is enabled through the chip select pin CS and accessed via a 3-wire interface consisting of serial data input SI, serial data output SO and serial clock SCK. All programming cycles are completely self-timed and no separate erase cycle is required before write. Block write protection is program enabled and separate program enable and disable instructions are provided for additional data protection. Hardware data protection provided to protect against inadvertent write attempts to the status register. Any serial communication suspension can be accomplished without resetting the serial sequence.
