The MCP795B20T-I/ST is a low-power Real-Time Clock/Calendar (RTCC) from Quarktwin Technology Ltd. It features a 32 kHz boot-up clock, 64 bytes of battery-backed SRAM, and 2 Kbits of EEPROM memory, with a write endurance of 1 million cycles. The device operates within a voltage range of 1.8V to 5.5V and has a low standby current of less than 1 ¬µA. It includes programmable alarms, a watchdog timer, and dual event detect inputs for enhanced functionality. The MCP795B20T-I/ST supports SPI communication at speeds up to 10 MHz and can log power-fail timestamps, making it suitable for applications requiring precise timekeeping and data retention during power outages. The operating temperature range is -40¬8C to +85¬8C, and it is available in a 14-lead TSSOP package.
