32K/64K-Bit SPI Serial CMOS E2PROM

DESCRIPTION The CAT25C32/64 is a 32K/64K-Bit SPI Serial CMOS EEPROM internally organized as 4Kx8/8Kx8 bits. Catalyst’s advanced CMOS Technology substantially reduces device power requirements. The CAT25C32/64 features a 64-byte page write buffer. FEATURES ■ 10 MHz SPI compatible ■ 1.8 to 6.0 v

64K SPI Bus Serial EEPROM

DESCRIPTION The Microchip Technology Inc. 25AA640/25LC640/25C640 (25xx640*) is a 64K bit serial Electrically Erasable PROM. 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
