Serial Flash Supports Variable Data And Parameter Storage

Targeting applications that involve large amounts of rapidly changing data and parameter information, the M45PE80 8-Mb serial flash memory is suitable for use in digital answering machines, pagers, digital cameras, home video game systems, and toys. Offering fine granularity, each page of 256 bytes can be individually erased and programmed, and a write instruction allows data to be updated at the byte level. One page of 256 bytes can be written in 12 ms, programmed in 2 ms, and erased in 10 ms. The device is accessed through a SPI bus with a clock rate of 25 MHz. Operating from a 2.7V to 3.6V supply, the serial flash includes a deep power-down mode that draws only 1 µA. Minimum data retention is 20 years and write endurance is 100,000 cycles. Available in an eight-pin MLP, price is $2.50 each/10,000. STMICROELECTRONICS, Lexington, MA. (781) 861-2650.
