C8051F002-GQ

Overview

The C8051F002-GQ is a mixed-signal microcontroller from Silicon Labs featuring a high-speed 8051 CPU core with up to 25 MIPS throughput at a 25 MHz clock frequency. It integrates 32 KB of ISP FLASH memory and 256 bytes of internal SRAM. The device includes a 12-bit SAR ADC, two 12-bit DACs, two analog comparators, and an on-chip voltage reference. Digital peripherals include hardware SMBus, SPI, UART, and a programmable counter array. 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 64-pin TQFP package.

Feature Summary

• Integrated JTAG debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulation hardware.
• On-chip precision voltage reference generator providing stable 2.4V output with low temperature drift.
• Configurable digital crossbar allows flexible mapping of peripheral signals to general-purpose I/O pins.
• Supports multiple power-saving sleep and shutdown modes to optimize energy consumption.

Applications

• Industrial control systems requiring precise analog signal acquisition
• Data acquisition modules utilizing the integrated 12-bit ADC
• Embedded applications needing simultaneous serial communication via SMBus, SPI, and UART

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific GQR suffix matches the required 64-pin TQFP package dimensions. Ensure compliance with RoHS standards if applicable to your assembly process. Check for obsolescence notices as this family may be designated not recommended for new designs.

Selection Notes

Select this model when a complete mixed-signal solution is needed on a single chip. It is suitable for designs prioritizing development speed due to built-in JTAG debugging. Consider the 256-byte RAM limit for complex software architectures. Verify that the 32 KB flash capacity meets application storage requirements before finalizing the part choice.

Part Context

This component belongs to the C8051F0xx mixed-signal MCU family by Silicon Labs. It shares architectural similarities with variants like the C8051F000 and C8051F001, differing primarily in memory sizes and peripheral configurations. The family utilizes the CIP-51 CPU core, offering enhanced performance over traditional 8051 implementations while maintaining compatibility.

Replacement Considerations

Consult official Silicon Labs documentation for verified substitute part numbers within the C8051F series. Cross-reference pinouts and electrical characteristics carefully when considering alternatives.
