C8051F564-IQ

Overview

The C8051F564-IQ is an automotive-qualified, mixed-signal ISP Flash MCU from the C8051F55x/56x/57x family. It features a high-speed 8051 core delivering up to 50 MIPS at 50 MHz. The device integrates 32 kB of in-system programmable Flash memory and 2304 bytes of internal data RAM. Key analog peripherals include a 12-bit ADC with up to 200 ksps sampling rate and two comparators. Digital interfaces encompass CAN 2.0, LIN 2.1, UART, SMBus, and SPI. It operates on a supply voltage of 1.8 V to 5.25 V within a temperature range of –40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for extended temperature operation.
• Integrated full-featured CAN 2.0 and LIN 2.1 controllers eliminating external transceiver requirements.
• High-performance pipelined 8051 core executing most instructions in one or two system clocks.
• On-chip debug circuitry enabling non-intrusive in-system debugging without external emulators.

Applications

• Automotive body control modules
• Industrial sensor nodes
• LIN/CAN bus communication gateways

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors. Confirm the specific suffix matches the required package variant. Check current lifecycle status as this family may be subject to discontinuation notices. Ensure ESD handling protocols are followed during storage and assembly.

Selection Notes

Select this model when automotive reliability and integrated CAN/LIN connectivity are required. Verify that the 32 kB Flash capacity meets application firmware size constraints. Confirm pin compatibility if migrating from other members of the C8051F5xx series. Evaluate power consumption requirements against the typical operating current specifications.

Part Context

This component belongs to the C8051F55x/56x/57x family of mixed-signal microcontrollers designed for robust embedded applications. The family shares a common architecture but varies in memory size and I/O count. The C8051F564 variant specifically targets applications needing balanced performance and peripheral integration within a compact form factor.

Replacement Considerations

Pin-for-pin compatible alternatives within the same family include the C8051F560, C8051F561, C8051F562, C8051F563, C8051F565, C8051F566, and C8051F567. These parts share identical packages and core functionality but differ in Flash memory capacity or specific peripheral configurations.
