Microchip Technology MCP79411-I/MS
- Part Number:
- MCP79411-I/MS
- Manufacturer:
- Microchip Technology
- Ventron No:
- 3003623-MCP79411-I/MS
- Description:
- IC RTC CLK/CALENDAR I2C 8-MSOP
- Datasheet:
- MCP79411-I/MS
Description
The MCP7941X series of low-power Real-Time Clocks (RTCs) utilizes digital timing compensation for accurate timekeeping. It features a programmable output control for versatility, a power sense circuit for automatic backup supply switching, and nonvolatile memory for data storage. The RTC tracks time using internal registers and communicates via the I²C™ bus. It automatically adjusts for months with fewer than 31 days, including leap year corrections. The clock operates in 24-hour or 12-hour format with an AM/PM indicator and settable alarms. The programmable CLKOUT generates frequencies of 32.768, 8.192, 4.096 kHz, and 1 Hz from the external crystal. The device includes 64 bytes of battery-backed SRAM, 1 Kbits of EEPROM, and a 64-bit protected space for a unique ID or MAC address. It is accessible through the serial interface while Vcc is between 1.8V and 5.5V, but can operate down to 1.3V for timekeeping and SRAM retention.
Features
Real-Time Clock/Calendar (RTCC) with battery backup
Programmable output control for CLKOUT and alarm output
64 bytes of battery-backed SRAM
1 Kbits of EEPROM with block/sector write protection
