Description
NM25C640 64K-Bit Serial CMOS EEPROM (Serial Periphrial Interface (SPI) Synchronous Bus) PRELIMINARY March 1999 NM25C640 64K-Bit Serial CMOS EEPROM (.
Features
* s 2.75 MHz clock rate @ 4.5V to 5.5V 2.1 MHz @ 2.7V to 4.5V s 65,536 bits organized as 8,192 x 8 s Multiple chips on the same 3-wire bus with separate chip select lines s Self-timed programming cycle s Simultaneous programming of 1 to 32 bytes at a time s Status register can be polled during programApplications
* requiring both non-volatile memory and insystem data updates. This EEPROM is well suited for applications using the 68HC11 series of microcontrollers that support the SPI interface for high speed communication with peripheral devices via a serial bus to reduce pin count. The NM25C640 is implementedNM25C640 Distributors
