C8051F061

Overview

The C8051F061 is a mixed-signal microcontroller featuring a high-speed 8051 core operating at up to 24.5 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 supporting up to 1 Msps, a 10-bit SAR ADC, two 12-bit DACs, three analog comparators, and a precision voltage reference. Digital peripherals consist of a Bosch CAN 2.0B controller, SMBus, SPI, dual UARTs, five 16-bit timers, and a Programmable Counter Array. It provides 24 general-purpose I/O pins, on-chip JTAG debug circuitry, and operates within a supply voltage range of 2.7 V to 3.6 V across an industrial temperature range of -40°C to +85°C.

Feature Summary

• High-performance pipelined 8051 core delivering up to 25 MIPS execution speed
• Dual 16-bit SAR ADCs with direct memory access and windowed interrupt generation
• Integrated Bosch CAN 2.0B controller for robust serial communication
• On-chip non-intrusive JTAG debug interface with boundary scan support

Applications

• Industrial control systems requiring CAN bus connectivity
• Data acquisition systems utilizing high-resolution analog-to-digital conversion
• Portable medical equipment and test instrumentation
• Sensor processing nodes with integrated signal conditioning

Procurement Notes

Verify the specific package variant and ordering suffix against the manufacturer's current datasheet revision. Confirm that the required pin count and peripheral set match the C8051F061 designation rather than other family members like the F060 or F062. Ensure development tools are compatible with the CIP-51 architecture before initiating procurement.

Selection Notes

Select this component when both high-speed digital processing and precise analog signal handling are required within a single chip. The inclusion of CAN 2.0B makes it suitable for networked applications, while the dual 16-bit ADCs address demanding measurement tasks. Consider the 24-pin I/O limitation compared to the 59-pin variants if extensive digital interfacing is needed.

Part Context

This device belongs to the C8051F06x family of analog-intensive microcontrollers from Silicon Labs. These devices represent System-on-a-Chip solutions combining the CIP-51 core with extensive mixed-signal peripherals. The family shares architectural similarities but varies in I/O count, memory size, and specific peripheral availability across different model numbers.

Replacement Considerations
