C8051F501-IM

Overview

The C8051F501-IM is an 8-bit mixed-signal microcontroller from Silicon Labs, part of the C8051F50x family. It features a high-speed pipelined 8051 core operating at up to 50 MHz (50 MIPS). The device includes 64 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. Key peripherals include a 12-bit ADC with up to 200 ksps sampling rate, CAN 2.0 and LIN 2.1 controllers, multiple serial interfaces, and four 16-bit timers. It operates on a supply voltage of 1.8 V to 5.25 V and is qualified for automotive applications within a temperature range of –40 °C to +125 °C.

Feature Summary

• Integrated CAN 2.0 and LIN 2.1 controllers enable robust automotive communication without external transceivers or crystals.
• On-chip debug circuitry supports full-speed, non-intrusive in-system debugging via the C2 interface.
• High-performance 8051 core utilizes a pipelined architecture to execute most instructions in one or two system clocks.
• Comprehensive analog subsystem includes a 12-bit ADC, comparators, and a precision internal oscillator.

Applications

• Automotive body control modules
• Industrial sensor nodes
• LIN/CAN bus gateway devices
• Smart metering systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific package variant matches design requirements. Check for any product change notices regarding assembly or labeling updates. Ensure compatibility with existing development tools and programming interfaces before finalizing procurement decisions.

Selection Notes

Select this model when pin-for-pin compatibility with other C8051F50x/51x devices is required. Consider the 48-pin QFN package for space-constrained designs. Evaluate power consumption profiles against application needs, noting typical stop mode current specifications. Verify that the integrated analog peripherals meet signal conditioning requirements without external components.

Part Context

This component belongs to the C8051F50x/F51x mixed-signal ISP Flash MCU family. It shares architectural similarities with the C8051F51x series but differs in memory capacity and I/O count. The family emphasizes high integration by combining digital processing capabilities with extensive analog peripherals on a single chip.
