The AAAA Clock Demo demonstrates the capability of a PIC16F1933 microcontroller and MCP1624 boost controller running from a single sell AAAA battery at 1.5V. A MCP1624 boost controller is used to boost the single cell battery voltage up to 3.3 volts.

This board includes:
• Capacitive sense buttons for configuring the clock
• MCP1624 boost controller
• MCP9701A analog temperature sensor
• PIC16LF1933 microcontroller
• Fuel Gauge for measuring the battery voltage level
• Custom LCD (displaying time, temperature and battery voltage)
