Microchip Technology introduced their MCP794XX stand-alone I2C Real-Time Clock/Calendar (RTCC) family. The MCP794XX features on-chip EEPROM and SRAM, digital trimming for time-of-day calibration, battery-switchover, user-lockable section of EEPROM, 64-bit reprogrammable unique ID that can be factory-programmed with a MAC address. All six MCP794XX RTCC devices are available in 8-pin MSOP, SOIC, TSSOP and TDFN packages. The MCP79400 is priced at $0.64 each; the MCP79401, MCP79402 and MCP79410 at $0.70 each; and the MCP79411 and MCP79412 at $0.76 each, all in 10,000-unit quantities. The devices are ideal for smart-energy (thermostats, power meters and commercial refrigeration), home-appliance (stoves, dishwashers and microwave ovens), automotive (dashboard controls and car radios), and consumer-electronic markets (office equipment, irrigation controls and video systems).
