Silicon Labs Microcontrollers C8051F391-A-GM

The C8051F391-A-GM is an 8-bit microcontroller featuring 16 kB of Flash memory and is housed in a 24-pin QFN package. It operates with a supply voltage range of 1.8 to 3.6 V and includes a high-speed 8051 core capable of up to 50 MIPS throughput at a 50 MHz clock frequency. The device supports a variety of digital peripherals, including UART, SMBus (I¬=C compatible), and SPI interfaces, along with six general-purpose 16-bit timers and a programmable counter array. This microcontroller is equipped with a 10-bit ADC that can handle up to 16 external inputs, configurable for single-ended or differential modes, and features two 10-bit current output DACs. It also includes an on-chip precision temperature sensor and an analog comparator, which can be configured as an interrupt or reset source. The internal 49 MHz oscillator is calibrated for precision, and the device supports low-power modes with a stop mode current of 200 nA. The C8051F391-A-GM is suitable for applications requiring mixed-signal processing and offers robust debugging capabilities with on-chip debug circuitry, allowing for non-intrusive in-system debugging. Its operating temperature range extends from -40 to +105 ¬8C, making it suitable for a variety of environmental conditions.
