Microchip real-time clock/calendar range

The standalone real-time clock/calendar portfolio with the 10-pin, SPI MCP795XX family offers many of the same features as the larger 14-pin MCP795WXX family, including good timekeeping performance.

Reducing overall component count in the system and eliminating the user programming costs for a serial ID make the MCP795XX RTCC family suitable for the handheld, wireless and consumer markets. By including 64 bytes of SRAM, 2 Kbits of EEPROM and a 128-bit unique ID, which can be ordered blank or preprogrammed with a MAC address, extra memory devices may not be needed.

Utility power meters, manufacturing equipment, radios, GPS and hospital instrumentation applications that need accurate time over a broad temperature range will also benefit from the very wide digital trimming range, which can compensate up to 22 s/day for crystal frequency drift.
