C8051F063-GQR

Overview

The C8051F063-GQR is an 8-bit microcontroller from the Silicon Labs C8051F06x family, featuring a high-speed pipelined 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, a 10-bit SAR ADC, two 12-bit DACs, three analog comparators, and a precision voltage reference. Digital peripherals comprise a Bosch CAN 2.0B controller, hardware SMBus, SPI, and dual UARTs. It utilizes a 64-pin TQFP package and operates within a supply voltage range of 2.7 V to 3.6 V across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual 16-bit SAR ADCs with direct memory access and windowed interrupt generation alongside a 10-bit SAR ADC for versatile signal acquisition.
• Includes a dedicated Bosch CAN 2.0B controller for robust network communication, complemented by hardware SMBus, SPI, and dual UART interfaces.
• Features on-chip JTAG debug circuitry supporting full-speed non-intrusive in-circuit debugging with breakpoints and watchpoints.
• Provides two 12-bit DACs capable of timer-synchronized jitter-free waveform generation and three analog comparators with programmable hysteresis.

Applications

• Industrial control systems requiring precise analog measurement and CAN bus connectivity
• Data acquisition systems utilizing high-resolution 16-bit ADCs with DMA capabilities
• Embedded applications needing integrated JTAG debugging and in-system programming

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity and pin alignment against the 64-pin TQFP specification. Ensure environmental compliance documentation matches project requirements. Review datasheet revision history for any functional updates or errata applicable to this specific manufacturing lot before integration into final designs.

Selection Notes

Select this component when high-resolution analog conversion and CAN communication are required in a single chip. The 64-pin TQFP package suits space-constrained designs compared to the 100-pin variants. Consider the 2.7 V to 3.6 V supply constraint for power management. Evaluate the 24.5 MHz clock speed against processing demands. Verify that the 24 general-purpose I/O pins meet interface requirements.

Part Context

This part belongs to the C8051F06x series of fully integrated mixed-signal microcontrollers. The family shares a common CIP-51 core architecture but varies in pin count, I/O availability, and peripheral configurations. The C8051F063 specifically targets applications needing CAN support and high-resolution ADCs in a compact form factor. It represents a complete system-on-chip solution reducing external component count.

Replacement Considerations

Consult official Silicon Labs documentation for current lifecycle status. Check for recommended upgrades within the C8051F06x family or newer generations. Verify pin compatibility and peripheral equivalence if substituting with other 8-bit MCUs. Review end-of-life notifications for potential supply constraints.
