C8051F375-A-GM

Overview

The C8051F375-A-GM is an 8-bit mixed-signal MCU from Silicon Labs, featuring a high-speed pipelined 8051 core operating at up to 50 MIPS with a 50 MHz clock. It integrates 16 kB of in-system programmable Flash memory and 512 bytes of byte-programmable EEPROM. The device includes a 10-bit ADC with programmable throughput up to 500 ksps, two 10-bit current output DACs, and a precision temperature sensor accurate to ±2 °C. It operates on a supply voltage of 1.8 V to 3.6 V and supports interfaces including UART, two SMBus ports, and SPI.

Feature Summary

• Integrated on-chip debug circuitry enables full-speed, non-intrusive in-system debugging without external emulators.
• Features a low-power stop mode with current consumption as low as 200 nA for energy-efficient applications.
• Includes a precision internal oscillator supporting crystal-less UART operation and fast wake times from suspend modes.

Applications

• Battery-powered portable devices requiring low power consumption
• Industrial control systems utilizing analog signal processing
• Data acquisition systems with multi-channel sensing requirements

Procurement Notes

Verify the specific revision level and package type against the official datasheet before procurement. Confirm that the ordering suffix matches the required temperature range and packaging format. Ensure compatibility with existing design constraints regarding supply voltage and interface availability. Check for any end-of-life notices or alternative part recommendations from the manufacturer.

Selection Notes

Select this component when a fully integrated mixed-signal solution is needed with on-chip calibration capabilities. The inclusion of EEPROM allows for non-volatile data storage without external components. Consider the pin count and peripheral set relative to the application's I/O and communication requirements. Evaluate the power modes available to meet specific standby and active current specifications.

Part Context

This microcontroller belongs to the C8051F39x/37x family, which shares architectural similarities but differs in peripheral sets and package options. The 'F37x series specifically targets industrial and commercial temperature ranges. It serves as a drop-in replacement for older C8051F33x devices with enhanced performance and additional analog peripherals.
