AT25640B-SSPDGV-T – SPI Serial EEPROM – Microchip

The Microchip AT25640B-SSPDGV-T is a 64 Kbit (8,192 x 8) SPI Serial EEPROM in an 8-lead SOIC package, operating from 1.8V to 5.5V with a 20 MHz clock rate. RoHS-compliant, tape-and-reel packaging.

The AT25640B-SSPDGV-T from Microchip Technology (originally Atmel) is a 64 Kbit SPI Serial EEPROM organized as 8,192 words x 8 bits. Built on the industry-standard Serial Peripheral Interface (SPI) bus, it supports SPI Modes 0 (0,0) and 3 (1,1) and operates across a wide 1.8V to 5.5V supply range, making it ideal for both low-voltage and standard-voltage embedded designs. This variant ships in an 8-lead SOIC (narrow, 3.90 mm body) package on tape and reel (“-T”), with Green / Pb- and Halide-free, RoHS-compliant construction.
