Serial Flash Ensures Compatibility

Guaranteeing backward compatibility with serial EEPROMs with regards to pin-out, the M25PE family of serial flash memories maintains the SPI-standard pinout across devices offering 1-, 2-, and 4-Mb densities. Access to the devices is through the SPI bus with an enhanced clock speed of 25 MHz. They operate on 2.7V to 3.6V supply voltages with a power consumption of 1 µA in power-down mode. The 1- and 2-Mb devices come in S08 Narrow packages (150 mils), and the 4-Mb members are available in S08 Wide packages (208 mils). Each member of the family is also available in an 8-pin, 5 mm x 6 mm MLP. Other shared features include a minimum data retention of 20 years, write endurance of 100,000 cycles, and an operating temperature range from -40°C to 85°C. Prices for 1-, 2-, and 4-Mb devices are $0.70 (M25PE10), $0.85 (M25PE20), and $1 (M25PE40) each/10,000, respectively. STMICROELECTRONICS INC., Lexington, MA. (888) 787-3550.
