C8051F367-GM

Overview

The C8051F367-GM is a mixed-signal ISP Flash microcontroller from Silicon Labs, featuring a high-speed 8051 core with up to 50 MIPS throughput. It integrates 32 kB of in-system programmable Flash memory and 1280 bytes of internal data RAM. The device includes a 10-bit ADC supporting up to 200 ksps with 21 external inputs, a 10-bit current output DAC, and two comparators. Digital peripherals consist of hardware-enhanced UART, SMBus, SPI, four 16-bit timers, and a 16-bit PCA. It operates within a supply voltage range of 2.7 V to 3.6 V and supports temperatures from -40 °C to +85 °C in a 28-pin QFN package.

Procurement Notes

Verify the specific revision level against the manufacturer's documentation prior to procurement. Confirm that the component meets all required environmental specifications for the intended application environment. Ensure compatibility with existing development tools and debug interfaces. Check for any obsolescence notices or lifecycle status updates from the manufacturer before finalizing orders.

Selection Notes

Select this component when a fully integrated mixed-signal solution is required alongside an 8051-compatible instruction set. Consider the available I/O count and peripheral set relative to system complexity. Evaluate the power consumption characteristics against battery-operated requirements if applicable. Verify that the package dimensions fit the target PCB layout constraints.

Part Context

This device belongs to the C8051F36x family of mixed-signal microcontrollers designed for cost-sensitive and high-performance embedded applications. The family shares common architectural features while varying in memory size and pin counts. The C8051F367 variant specifically offers 32 kB Flash and utilizes a 28-pin QFN package, distinguishing it from larger pin-count counterparts in the series.

Replacement Considerations

Consult official substitution lists for compatible devices within the same product family. Verify pinout compatibility and electrical parameter alignment before replacing components in existing designs.
