C8051F353-GM

Overview

The C8051F353-GM is an 8-bit mixed-signal microcontroller from Silicon Labs, part of the C8051F35x family. It features a high-speed pipelined 8051 core operating at up to 50 MHz (50 MIPS). The device includes 8 kB of in-system programmable Flash memory and 768 bytes of on-chip RAM. Key analog peripherals consist of a 24-bit sigma-delta ADC with an 8-input multiplexer and programmable gain amplifier, two 8-bit current-output DACs, and a voltage comparator. Digital interfaces include UART, SMBus, and SPI. It operates within a supply voltage range of 2.7 V to 3.6 V and supports temperatures from -40°C to +85°C.

Feature Summary

• High-performance 8051 core with pipelined architecture delivering up to 50 MIPS throughput.
• Integrated 24-bit sigma-delta ADC subsystem featuring an 8-channel multiplexer and programmable gain stage.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Flexible digital I/O with priority crossbar decoder allowing configurable pin mapping for multiple serial protocols.

Applications

• Data acquisition systems requiring high-resolution analog input processing
• Industrial control applications utilizing precise sensor interfacing
• Embedded devices needing in-circuit reprogrammable firmware storage
• Battery-powered instruments benefiting from low-power stop modes

Procurement Notes

Verify the specific suffix 'GM' corresponds to the 28-pin QFN package variant when sourcing. Confirm that the component status aligns with project requirements, as this family may be designated as not recommended for new designs. Ensure compatibility with existing PCB footprints for the 28-lead quad flat no-lead form factor.

Selection Notes

Select this model for applications demanding high-resolution analog conversion alongside standard digital control functions. The 24-bit ADC capability distinguishes it from lower-resolution variants in the series. Consider the 28-pin package constraint if board space is limited compared to the 32-pin LQFP option available in the same family.

Part Context

This component belongs to the C8051F35x series of analog-intensive microcontrollers. It shares the same core architecture and peripheral set as the C8051F350, F351, and F352, differentiated primarily by package options and minor configuration variations. The series represents a fully integrated system-on-chip solution combining CPU, memory, and extensive analog/digital peripherals.
