C8051F000-GQ

Overview

The C8051F000-GQ is a mixed-signal microcontroller from Silicon Labs featuring a pipelined CIP-51 core with up to 25MIPS throughput at 25MHz. It integrates 32KB ISP FLASH and 256 bytes of internal SRAM. The device includes a 12-bit SAR ADC, two 12-bit DACs, analog comparators, and a precision voltage reference. Digital peripherals include SMBus, SPI, UART, PCA, and four general-purpose timers. It operates on a 2.7V to 3.6V supply within the -40°C to +85°C temperature range.

Feature Summary

• On-chip JTAG debug circuitry enables full-speed, non-intrusive in-system debugging without external emulation hardware.
• Integrated high-speed controller core executes 70% of instructions in one or two system clock cycles for enhanced performance.
• Programmable digital I/O crossbar allows flexible pin configuration with all ports being 5V tolerant.

Applications

• Industrial control systems requiring mixed-signal processing
• Data acquisition applications utilizing integrated ADC and DAC
• Embedded systems needing in-system programmability

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt. Check revision markings against official datasheets. Ensure storage conditions comply with moisture sensitivity levels. Validate part numbers before integration into production lines.

Selection Notes

Select this model when 256 bytes of RAM suffices for application requirements. Choose over variants with larger RAM if cost or specific peripheral sets are prioritized. Verify that the 12-bit ADC resolution meets signal conditioning needs. Ensure the 32KB flash capacity accommodates firmware size. Consider power consumption profiles relative to the 25MHz maximum frequency.

Part Context

This component belongs to the C8051F0xx family of mixed-signal MCUs. It shares architectural similarities with the C8051F005/06/07 series but differs in internal RAM size. The GQ suffix indicates a 64-pin TQFP package. This family emphasizes complete system integration by combining analog and digital peripherals on a single chip.

Replacement Considerations

Public confirmed substitute part numbers: None identified in verified documentation.

FAQ

Does the C8051F000 support in-system programming?

Yes, it features 32KB of ISP FLASH memory that can be reprogrammed in 512-byte sectors without special external programming voltages.
