C8051F411-GM

The C8051F411-GM is an 8‑bit microcontroller from Silicon Labs (C8051F4xx family). It uses an enhanced 8051-compatible core with on‑chip Flash for firmware and on‑chip RAM. It provides a rich set of peripherals, including multi-channel 12‑bit ADCs, DACs, precision comparators, timers and PWM channels, and multiple serial interfaces (UARTs, SPI, I2C). It supports various power modes and a watchdog timer, making it suitable for embedded control, sensing, and data‑acquisition applications. The “GM” suffix denotes a specific package variant for the device (placement/pinout options defined in the datasheet). Development is supported by Silicon Labs tools (and third‑party IDEs/toolchains) with in‑system programming and debugging via the C2 interface. In short, the F411-GM combines 8051 compatibility with integrated analog and digital peripherals in a compact package, ideal for cost‑conscious, mixed-signal embedded applications.

Here are the key features of the C8051F411-GM (Silicon Labs):
