C8051F311-GM

The C8051F311-GM is an 8‑bit microcontroller from Silicon Labs (Cygnal) in the C8051F31x family, based on an enhanced 8051 core with on‑chip memory and peripherals.
Key features:
- On‑chip memory: program Flash and RAM (no external memory required for code/data).
- Peripherals: multiple I/O ports, timers (often 16‑bit), PWM, UART, SPI, I2C/SMBus, and analog peripherals such as ADC and comparators.
- Clocking: flexible clock options, including an on‑chip oscillator and external crystal support.
- Power management: several low‑power modes for energy efficiency.
- Debug/Programming: in‑system programming and debugging via an on‑chip interface.
- Packaging: available in the GM package (check datasheet for pin count and dimensions).
Typical uses:
- Compact control and data‑acquisition applications, sensor interfacing, portable/embedded devices requiring analog and digital peripherals in a small footprint.
Toolchain and support:
- Silicon Labs Simplicity Studio, Keil, IAR, or SDCC; consult the datasheet and user guide for exact specs, memory sizes, and pinout.
