C8051F061R

Overview

The C8051F061R is an 8-bit mixed-signal microcontroller from Silicon Labs, featuring a high-speed CIP-51 core operating at up to 25 MIPS with a 25 MHz clock. It integrates 64 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. Key peripherals include two 16-bit SAR ADCs supporting up to 1 Msps throughput, two 12-bit DACs, three analog comparators, and a Bosch CAN 2.0B controller. The device provides 24 general-purpose I/O pins via a programmable digital crossbar and supports multiple power-saving modes within a 2.7V to 3.6V supply range.

Feature Summary

• Integrates dual 16-bit SAR ADCs with direct memory access for high-speed data acquisition without software overhead.
• Includes a hardware Bosch CAN 2.0B controller for robust serial communication.
• Features on-chip JTAG debug circuitry enabling full-speed, non-intrusive in-circuit debugging.
• Supports simultaneous operation of SMBus, SPI, and dual UART serial ports.

Applications

• Industrial control systems requiring CAN bus connectivity
• Data acquisition systems utilizing high-resolution analog inputs
• Embedded devices needing precise waveform generation via synchronized DACs

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging configuration when sourcing components. Confirm that the ordered part matches the exact silicon revision required for your design. Ensure compatibility with existing development tools such as Keil C51 or Silicon Labs IDE. Check for any RoHS compliance documentation relevant to your manufacturing region requirements.

Selection Notes

Select this component if your application requires integrated CAN functionality alongside high-resolution analog conversion capabilities. The 24-pin I/O count suits designs where pin count is constrained but peripheral density is high. Consider the 25 MIPS execution speed for real-time processing tasks. Evaluate the 2.7V to 3.6V voltage range against your system power architecture.

Part Context

This device belongs to the C8051F06x family of fully integrated mixed-signal System-on-Chip microcontrollers. It shares architectural similarities with the C8051F060 but differs in I/O pin count and external memory interface availability. The family emphasizes high performance through pipelined instruction execution and extensive on-chip analog and digital peripherals.

Replacement Considerations

C8051F060R serves as a functional substitute with identical core specifications but offers additional GPIO pins and external memory interface support. Verify pinout compatibility before substitution due to the difference in available I/O lines between the two variants.
