C8051F374-A-GM

Overview

The C8051F374-A-GM is an 8-bit mixed-signal microcontroller featuring a high-speed 50 MIPS pipelined 8051 core. 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 up to 500 ksps throughput, two 10-bit current output DACs, and a precision temperature sensor accurate to ±2 °C. Operating on a 1.8 V to 3.6 V supply, it supports interfaces including UART, dual SMBus, and SPI within a 24-pin QFN package.

Feature Summary

• On-chip debug circuitry enables full-speed, non-intrusive in-system debugging without external emulators.
• Integrated analog peripherals include a 10-bit ADC, dual 10-bit current DACs, and a comparator with programmable hysteresis.
• Low power operation features a 200 nA Stop mode current and fast wake times from suspend modes.

Applications

• Battery-powered embedded systems requiring low standby current
• Industrial control applications utilizing precision sensing
• Data acquisition systems with mixed-signal requirements

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's latest documentation to confirm pinout compatibility and electrical characteristics. Confirm that the 24-pin QFN package matches your PCB land pattern specifications. Ensure the operating voltage range aligns with your system design constraints before finalizing procurement.

Selection Notes

Select this component for designs requiring a fully integrated mixed-signal solution with on-chip calibration capabilities. The inclusion of a precision temperature sensor eliminates the need for external components. Consider the 512-byte EEPROM for data storage needs where Flash endurance may be insufficient.
