Microchip's MCP7940N Real-Time Clock/Calendar
Building upon the success of the MCP794XX family of products, Microchip is introducing the MCP7940N, which offers battery switchover and timestamp for accurate timekeeping, digital trimming for time-of-day calibration and 64 bytes of SRAM. Starting at $0.57 each in 10,000-unit quantities, it offers a lower-cost alternative to the existing MCP7941X devices, which feature 1Kbit of EEPROM memory and a 64-bit reprogrammable unique ID.
