C8051F007R

Overview

The C8051F007R is a mixed-signal System-on-Chip microcontroller from Silicon Labs, featuring a high-speed 8051-compatible core operating at up to 25 MIPS with a 25 MHz clock. It integrates 32 KB of in-system programmable Flash memory and 2304 bytes of internal data RAM. The device includes a 12-bit SAR ADC with programmable gain amplifier, two 12-bit DACs, analog comparators, and a precision voltage reference. Digital peripherals consist of hardware SMBus, SPI, and UART interfaces, alongside a Programmable Counter Array and multiple timers.

Feature Summary

• High-performance pipelined CIP-51 CPU executes most instructions in one or two system clocks
• Integrated 12-bit ADC with programmable gain amplifier and windowed interrupt generator
• On-chip JTAG debug circuitry enables full-speed non-intrusive in-system debugging
• Programmable digital crossbar allows flexible assignment of peripheral signals to I/O pins

Applications

• Data acquisition systems requiring multi-channel signal processing
• Industrial control applications utilizing integrated analog peripherals
• Embedded communication devices using concurrent serial interfaces
• Sensor interface circuits leveraging the built-in temperature sensor

Procurement Notes

Verify the specific package variant (TQFP-64, TQFP-48, or LQFP-32) matches the design requirements, as the suffix indicates physical form factor. Confirm that the R suffix corresponds to the correct tape-and-reel packaging if automated assembly is planned. Ensure development tools support the C8051F00x family architecture for proper firmware deployment.

Selection Notes

Select this component when a complete mixed-signal solution is required without external analog components. The C8051F007R is suitable for designs needing high-resolution ADC conversion and precise DAC output within a single chip. Consider the 2304-byte RAM size for complex algorithm implementation compared to lower-capacity variants in the series.

Part Context

This part belongs to the C8051F00x/01x mixed-signal MCU family, which combines an 8051-compatible processor with extensive on-chip analog and digital peripherals. The family is characterized by its true system-level integration, reducing board space and component count. It utilizes the CIP-51 core for enhanced instruction throughput over standard 8051 architectures.

Replacement Considerations

Consult official Silicon Labs documentation for verified substitute part numbers within the C8051F series or EFM8 families. Cross-reference pinouts and peripheral sets to ensure functional compatibility before replacing the component.
