C8051F507-IM

Overview

The C8051F507-IM is an 8-bit mixed-signal microcontroller from Silicon Labs, featuring a high-speed pipelined 8051 core operating at up to 50 MHz. It integrates 32 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM (256 + 4096 XRAM). The device includes a 12-bit ADC with up to 200 ksps throughput and 25 external single-ended inputs, two voltage comparators, and a built-in temperature sensor. Digital peripherals consist of hardware UART, SMBus, SPI, CAN 2.0, LIN 2.1 controllers, four 16-bit timers, and a 16-bit PCA with six capture/compare modules. It operates on a supply voltage of 1.8 V to 5.25 V and supports -40 °C to +125 °C automotive-grade operation.

Feature Summary

• High-performance 8051 core with pipelined architecture delivering up to 50 MIPS throughput.
• Integrated analog subsystem including a 12-bit ADC, dual comparators, and temperature sensor.
• Comprehensive digital communication interfaces supporting CAN 2.0, LIN 2.1, UART, SMBus, and SPI.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.

Applications

• Automotive sensor interface and monitoring systems
• Industrial control and motor drive applications
• Embedded systems requiring robust CAN/LIN connectivity

Procurement Notes

Verify the specific package variant, as the datasheet indicates QFN-32 for this model number. Confirm that the application environment meets the specified -40 °C to +125 °C operating range. Ensure development tools support the C2 interface for programming and debugging. Check for any relevant product change notices or end-of-life announcements prior to final design commitment.

Selection Notes

Select this component when a fully integrated mixed-signal MCU with automotive qualification is required. It is suitable for designs needing multiple serial communication protocols and high-resolution analog acquisition within a compact footprint. Consider the 32 kB Flash limit for complex firmware requirements. Evaluate power consumption profiles against the typical stop mode current specifications if battery operation is critical.

Part Context

This part belongs to the C8051F50x/F51x family of mixed-signal ISP Flash MCUs. The family shares a common architectural foundation but varies in Flash size, I/O count, and package options. The C8051F507 specifically utilizes the 32-pin configuration, distinguishing it from higher-capacity variants like the C8051F501 which offer larger memory and more pins.

Replacement Considerations

Silicon Labs recommends EFM8BB52F16I-QFN20 as a replacement for related parts in this series due to end-of-life status for some legacy models. Verify pinout compatibility and peripheral availability before substituting.
