C8051F007-GQR

Overview

The C8051F007-GQR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F0xx family, featuring a high-speed CIP-51 CPU core with up to 25 MIPS throughput at a 25 MHz clock frequency. It integrates 32 KB of in-system programmable (ISP) Flash memory and 2304 bytes of internal SRAM. The device includes a 12-bit SAR ADC with programmable gain amplifier, two 12-bit DACs, analog comparators, and a precision voltage reference. Communication interfaces include hardware SMBus, SPI, and UART. It operates on a supply voltage of 2.7V to 3.6V within a temperature range of –40°C to +85°C and is housed in a 64-pin TQFP package.

Feature Summary

• Integrates a high-speed pipelined CIP-51 CPU core capable of executing 70% of the instruction set in one or two system clocks for efficient processing.
• Features comprehensive on-chip analog peripherals including a 12-bit ADC with programmable window detector, dual 12-bit DACs, and configurable analog comparators.
• Supports full-speed non-intrusive in-system debug via on-chip JTAG circuitry without requiring external emulation hardware.
• Provides concurrent digital serial communication capabilities through hardware-implemented SMBus, SPI, and UART ports.

Applications

• Data acquisition systems utilizing the integrated 12-bit ADC and programmable gain amplifier
• Industrial control applications requiring precise analog signal generation via dual DACs
• Embedded systems needing robust in-system programming and debugging capabilities
• Battery-powered devices leveraging multiple power-saving sleep and shutdown modes

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number and revision details against official Silicon Laboratories documentation. Confirm that the specific package variant matches the required pinout and thermal specifications for the target application environment. Ensure compliance with RoHS directives as indicated in the product selection guide. Review the datasheet for any specific handling precautions related to moisture sensitivity levels prior to assembly.

Selection Notes

Select this component when a complete mixed-signal solution is required on a single chip, eliminating the need for external ADCs or DACs. The C8051F007-GQR is suitable for designs prioritizing low pin count integration with extensive analog functionality. Consider the 2304-byte RAM size for complex data buffering requirements. Evaluate the 2.7V to 3.6V operating range against the system power supply constraints to ensure stable operation across all intended environmental conditions.

Part Context

This microcontroller belongs to the C8051F0xx series, which are fully static mixed-signal System-on-Chip solutions. The series is characterized by its direct competition between flash-based microcontrollers and mixed-signal capabilities. The C8051F007 variant specifically distinguishes itself within the family by offering higher RAM capacity compared to base models like the F000, while maintaining the same 32 KB Flash and advanced analog peripheral suite found in the broader F00x/F01x lineup.
