C8051F300-GM

The C8051F300-GM is an 8‑bit, 8051‑core microcontroller from Silicon Labs (Cygnal) in the C8051F300 family. It combines on‑chip Flash program memory and RAM with a broad peripheral set for embedded control.
Key points:
- 8051-compatible CPU with multi‑MHz performance and fast interrupt handling.
- On‑chip memory: Flash for code and RAM for data (exact sizes vary by variant).
- Peripherals: multiple I/O pins, timers, UART/SPI/I2C serial interfaces, PWM outputs, and an on‑chip ADC for analog sensing (DAC/analog features vary by device).
- System features: watchdog timer, low‑power modes, on‑chip oscillator, and in‑system programming support.
- GM suffix: identifies the package type/temperature grade for this specific device variant; exact pin count, memory, and peripherals depend on the exact F300-GM part.
- Tools: development with Silicon Labs Simplicity Studio (plus third‑party tools like Keil/IAR).
If you need precise specs (flash/RAM size, I/O count, ADC channels), consult the C8051F300/GМ datasheet for the exact part number.

Key features of the C8051F300-GM (8-bit microcontroller, Silicon Labs) include:
- 8051-compatible core, up to ~25 MHz operation.
- On-chip program Flash and RAM (no external memory required).
- 12-bit ADC with multiple input channels; integrated analog features.
- Multiple serial interfaces: UART, SPI, I2C (SMBus/I2C).
- Timers: several 16-bit timers; watchdog timer.
- PWM outputs and capture/compare capability.
- Flexible GPIO via crossbar switch and configurable peripherals mapping.
- Brown-out/reset, voltage reference options, and robust power management.
- Low-power modes with fast wake-up for sleep/idle operation.
- On-chip oscillator options and broad supply voltage range (typical 2.0–3.6 V).
- Package: GM variant available in supported packages.
Note: exact memory sizes and peripheral counts vary by specific F300-GM revision; consult the datasheet for precise figures.
