C8051F853-C-GU

Overview

The C8051F853-C-GU is an 8-bit microcontroller from the C8051F85x family, featuring a high-speed CIP-51 core with up to 25 MIPS throughput at a 25 MHz clock. It integrates 8 kB of in-system programmable Flash memory and 512 Bytes of RAM. The device includes a 12-bit ADC with up to 16 input channels, two analog comparators, and communication peripherals such as UART, I2C/SMBus, and SPI. Operating within a 2.2 V to 3.6 V supply range, it supports industrial temperatures (-40°C to +125°C) and is housed in a 24-pin QSOP package.

Feature Summary

• High-Speed CIP-51 Core: Pipelined architecture delivering up to 25 MIPS at 25 MHz using standard 8051 instructions.
• On-Chip Debug Circuitry: Facilitates full-speed, non-intrusive in-system debugging without external emulators.
• 12-Bit Analog-to-Digital Converter: Supports up to 16 input channels with internal or external voltage reference options.
• Crossbar-Enabled I/O: Up to 18 pins with configurable digital crossbar routing and 5 V tolerance.

Applications

• Industrial control systems requiring robust 8-bit processing
• Sensor data acquisition with integrated ADC capabilities
• Embedded applications needing on-chip debug and low power modes

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors. Confirm the specific ordering suffix matches required temperature grades and packaging. Check for end-of-life status as this family may be discontinued. Ensure compatibility with existing design tools and development environments before procurement.

Selection Notes

Select this model for designs requiring 8 kB Flash and 512 Bytes RAM in a 24-pin QSOP package. Consider the -Gx suffix for commercial temperature ranges (-40°C to +85°C) versus -Ix for industrial (-40°C to +125°C). Evaluate pin count requirements against the 18 available I/Os. Verify voltage supply constraints align with the 2.2 V to 3.6 V operating range.

Part Context

Part of the C8051F85x/86x low-cost 8-bit MCU family. Features include in-system programmable Flash, on-chip debug, and mixed-signal peripherals. Qualified to AEC-Q100 standards. Not recommended for new designs per manufacturer documentation.

Replacement Considerations

Check for EOL status. Potential substitutes include other C8051F series devices with similar Flash/RAM sizes and QSOP-24 packages. Verify pinout compatibility and peripheral availability before substitution.
