Description : 4K-BIT SERIAL INTERFACE CMOS EEPROM (SERIAL PERIPHERAL INTERFACE (SPI?) SYNCHRONOUS BUS) View

General Description
The NM25C041 is a 4096-bit MODE 1 SPI (SERIAL PERIPHERAL INTERFACE) CMOS EEPROM which is designed for high-reliability non-volatile data storage applications. The SPI INTERFACE features a byte-wide format (all data is transferred in 8-bit words) to INTERFACE with the Motorola 68HC11 microprocessor, or equivalent, at a 2.1MHz clock transfer rate. (This INTERFACE is considered the fastest SERIAL communication method.) This 4-wire SPI INTERFACE allows the end user full EEPROM functionality while keeping pin count and space requirements low for maximum PC board space utilization.

Features
■ 2.1 MHz clock rate @ 2.7V to 5.5V
■ 4096 bits organized as 512 x 8
■ Multiple chips on the same 3 wire BUS with separate chip select lines
■ Self-timed programming cycle
■ Simultaneous programming of 1 to 4 bytes at a time
■ Status register can be polled during programming to monitor RDY/BUSY
■ Both the Write Protect (WP) pin and auto-write disable after programming provides hardware and software write protection
■ Block write protect feature to protect against accidental writes
■ Endurance: 1,000,000 data changes
■ Data retention greater than 40 years
■ Packages available: 8-pin DIP and 8-pin SO
