C8051F411-GM

The C8051F411-GM is an 8-bit microcontroller based on the 8051 core, manufactured by Silicon Labs. It is part of the C8051F41x series and operates at up to 50 MHz, delivering 50 MIPS throughput. The device integrates 32 KB of Flash program memory and 2.25 KB of internal data RAM.

This microcontroller features a 12-bit ADC with up to 200 ksps sampling rate and 24 external inputs, along with two 12-bit current-mode DACs. It includes two comparators, four 16-bit timers, and a programmable counter array. Connectivity options include SMBus (I2C), SPI, and UART serial interfaces. On-chip peripherals also include a brown-out detector, power-on reset, PWM, temperature sensor, and watchdog timer.

The device is supplied in a 28-pin QFN package (5x5 mm) with an exposed pad for thermal management. It supports a supply voltage range of 2.0V to 5.25V and operates over the industrial temperature range of -40°C to +85°C. The oscillator type is internal, with an accuracy of 2% at 24.5 MHz, and can be multiplied up to 50 MHz.

With its rich analog and digital peripherals, the C8051F411-GM is suitable for embedded control applications requiring mixed-signal processing, such as sensor interfaces, motor control, and industrial automation. The on-chip debug circuitry enables full-speed non-intrusive debugging without an emulator.
