C8051F062R

Overview

The C8051F062R is a mixed-signal System-on-Chip microcontroller from Silicon Labs, featuring a high-speed pipelined 8051 core operating at up to 25 MHz with 25 MIPS throughput. It integrates 64 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. The device includes two 16-bit SAR ADCs capable of 1 Msps throughput, a 10-bit SAR ADC, two 12-bit DACs, three analog comparators, and a precision voltage reference. Digital peripherals include a Bosch CAN 2.0B controller, SMBus, SPI, dual UARTs, and an external memory interface. It operates on a 2.7 V to 3.6 V supply within the -40 °C to +85 °C temperature range.

Feature Summary

• High-performance 8051 core with pipelined architecture for fast instruction execution
• Dual 16-bit SAR ADCs with direct memory access and windowed interrupt generation
• Integrated Bosch CAN 2.0B controller for robust network communication
• On-chip JTAG debug circuitry supporting non-intrusive in-circuit debugging

Applications

• Industrial control systems requiring precise analog signal processing
• Automotive applications utilizing CAN bus communication
• Data acquisition systems with multi-channel high-resolution sampling
• Test and measurement equipment needing integrated DAC and comparator functions

Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging when ordering. Confirm the revision level matches project requirements as datasheet revisions may update electrical characteristics or pin definitions. Ensure the selected package variant aligns with PCB footprint constraints. Check for any end-of-life notices or last-time buy notifications prior to finalizing procurement plans.

Selection Notes

Select this component when high-speed analog conversion and CAN connectivity are required in a single chip. The 64 kB Flash capacity supports complex firmware without external memory. Consider the 100-pin TQFP package for maximum I/O availability. Evaluate power consumption across sleep modes if battery operation is intended. Verify that the 2.7 V to 3.6 V supply range fits the system design.

Part Context

This part belongs to the C8051F06x family of mixed-signal microcontrollers. It shares the same core architecture and peripheral set as the C8051F060, differing primarily in package options and minor configuration details. The family is designed for applications demanding high integration, reducing board space and component count compared to discrete solutions.
