C8051F564-IM

Overview

The C8051F564-IM is an 8-bit mixed-signal ISP Flash MCU from the Silicon Labs C8051F56x family. It features a high-speed CIP-51 core operating at up to 50 MHz, providing 50 MIPS throughput. The device includes 32 kB of in-system programmable Flash memory and 2304 bytes of internal data RAM (256 + 2048 XRAM). Key peripherals include a 12-bit ADC with up to 200 ksps sampling rate, two comparators, CAN 2.0 and LIN 2.1 controllers, and multiple serial interfaces. It operates on a supply voltage of 1.8 V to 5.25 V and is housed in a 32-pin QFN package.

Feature Summary

• Integrated CAN 2.0 and LIN 2.1 controllers that operate without requiring external crystals
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging
• High-speed pipelined CIP-51 microcontroller core executing most instructions in one or two system clocks
• 12-bit analog-to-digital converter supporting up to 200 ksps with selectable gain and window detection

Applications

• Automotive body control modules
• Industrial sensor nodes
• LIN/CAN bus gateway devices
• Portable instrumentation

Procurement Notes

Verify component authenticity through authorized channels as this part is marked Not Recommended for New Designs. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any errata updates relevant to the specific manufacturing lot before final integration into production systems.

Selection Notes

Select this component when automotive qualification under AEC-Q100 standards is required alongside integrated CAN and LIN capabilities. Ensure design requirements align with the 32 kB Flash capacity and 2304-byte RAM limit. Verify that the 32-pin QFN footprint fits the target PCB layout constraints.

Part Context

This device belongs to the C8051F55x/56x/57x family of mixed-signal MCUs. It shares architectural similarities with other members like the C8051F567-IM but differs in specific memory sizes and peripheral configurations. The family is designed for applications needing robust digital communication interfaces combined with precise analog signal processing capabilities.
