C8051F374-A-GMR

Overview

The C8051F374-A-GMR is an 8-bit mixed-signal microcontroller from Silicon Labs, featuring a high-speed CIP-51 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 range of 1.8 V to 3.6 V and is housed in a 24-pin QFN package.

Feature Summary

• Integrates a pipelined 8051-compatible core capable of executing 70% of instructions in one or two system clocks for high throughput.
• Includes on-chip debug circuitry that facilitates full-speed, non-intrusive in-system debugging without requiring external emulators.
• Features a precision internal oscillator supporting crystal-less UART operation and low-power suspend modes with fast wake times.
• Provides comprehensive analog peripherals including a 10-bit ADC, dual 10-bit current DACs, and a comparator with programmable hysteresis.

Applications

• Industrial control systems requiring precise analog signal acquisition and processing
• Battery-powered devices utilizing low-power stop and suspend modes
• Data acquisition systems leveraging the high-speed ADC and multiple serial interfaces
• Embedded applications needing in-system programming and direct on-chip debugging

Procurement Notes

Verify the specific revision level and ordering suffix against the manufacturer's latest documentation to ensure compatibility with your design requirements. Confirm the package type and temperature rating match your application specifications. Check for any end-of-life notices or alternative part recommendations from Silicon Labs before finalizing procurement plans.

Selection Notes

Select this component when a fully integrated mixed-signal solution is required to reduce bill of materials count. Consider the 16 kB Flash and 512 B EEPROM sizes relative to your code and data storage needs. Evaluate the 24-pin QFN package constraints against your PCB layout space. Ensure the 1.8 V to 3.6 V supply voltage range aligns with your system power architecture.

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 is designed as a drop-in replacement for legacy 8051 designs while offering enhanced performance and integrated analog features.

Replacement Considerations

Consult the datasheet section on C8051F33x compatibility for hardware incompatibilities if migrating from older silicon labs parts. Verify pinout and register mapping differences when substituting other members of the C8051F3xx family.
