C8051F063

Overview

The C8051F063 is an 8-bit mixed-signal microcontroller 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. The device includes two 16-bit SAR ADCs supporting up to 1 Msps throughput, a 10-bit SAR ADC with 200 ksps capability, and two 12-bit DACs. Digital peripherals comprise a Bosch CAN 2.0B controller, SMBus, SPI, dual UARTs, and multiple timers. It provides 24 general-purpose I/O pins via a programmable digital crossbar, operates within a 2.7 V to 3.6 V supply range, and supports industrial temperatures from -40 °C to +85 °C.

Procurement Notes

Verify the specific package variant and ordering suffix against the manufacturer's current datasheet before procurement. Confirm that the component meets RoHS compliance requirements for your target market. Ensure that the voltage supply rails align with the specified 2.7 V to 3.6 V operational range. Check for any end-of-life announcements or last-time buy notifications associated with this part number.

Selection Notes

Select the C8051F063 when a combination of high-speed digital processing and high-resolution analog conversion is required on a single chip. This model is suitable for applications needing CAN connectivity alongside precision measurement capabilities. Consider alternative models in the family if external memory interfaces or different pin counts are necessary. Evaluate the available development tools and compiler support for efficient firmware implementation.

Part Context

This microcontroller belongs to the C8051F06x series of fully integrated mixed-signal system-on-chip solutions by Silicon Labs. The series shares a common architectural foundation but varies in memory size, peripheral availability, and package options. It represents a generation of highly integrated 8-bit MCUs designed to reduce bill-of-materials costs by consolidating discrete components onto a single die.

Replacement Considerations

Consult official Silicon Labs documentation for verified substitute part numbers. Cross-reference pinouts and peripheral sets to ensure functional compatibility during migration.
