AT25M02-SSHM-B Product Details


The Atmel® AT25M02-SSHM-B provides 2,097,152 bits of Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 262,144 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation is essential. The device is available in space saving 8-lead JEDEC SOIC and 8-ball Thin WLCSP packages. In addition, the device operates from 1.7V to 5.5V. 

The AT25M02-SSHM-B 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 a separate erase cycle is not required before writing to the device.
