C8051F536-IM

Overview

The C8051F536-IM is an 8 kB ISP Flash microcontroller from the Silicon Labs C8051F52x/F53x family, operating on a high-speed pipelined 8051 core with up to 25 MIPS throughput at a 25 MHz system clock. It features a 12-bit ADC with programmable throughput up to 200 ksps and up to 16 external inputs, alongside a programmable comparator and built-in temperature sensor. The device includes 256 bytes of internal data RAM, hardware SPI, UART, and LIN 2.1 controller capabilities. It supports supply voltages from 2.0 to 5.25 V via a built-in LDO regulator and offers on-chip debug circuitry for non-intrusive in-system debugging.

Feature Summary

• Features a high-speed pipelined 8051 core executing 70% of instructions in one or two system clocks for efficient processing.
• Includes a 12-bit analog-to-digital converter with data-dependent windowed interrupt generation and built-in temperature sensing.
• Supports automotive qualification with operation across a wide temperature range of –40 to +125 °C compliant to AEC-Q100.
• Provides flexible digital peripherals including LIN 2.1 controller without crystal requirement and configurable port I/O.

Applications

• Automotive embedded systems requiring AEC-Q100 compliance
• Industrial control applications utilizing LIN bus communication
• Sensor interface modules leveraging 12-bit ADC and temperature monitoring
• Battery-powered devices benefiting from low-power operating modes

Procurement Notes

Verify the specific suffix 'IM' corresponds to the 20-pin QFN package as documented in the official datasheet. Confirm that the ordering code matches the 8 kB Flash variant within the C8051F53x family. Ensure compatibility with the required voltage range and temperature specifications for your target environment before finalizing procurement.

Selection Notes

Select this component when automotive-grade reliability and LIN 2.1 master/slave capability are required without external crystals. The integrated 12-bit ADC and comparator reduce external component count for signal conditioning tasks. Consider the 25 MIPS performance and 8 kB Flash size against application memory and speed requirements. Verify package availability in 20-pin QFN format if space constraints dictate this form factor.

Part Context

This part belongs to the C8051F52x/F53x series of mixed-signal microcontrollers designed for cost-sensitive and space-constrained applications. The family shares a common architecture featuring the CIP-51 core and extensive analog peripherals. The C8051F536-IM specifically denotes the 8 kB Flash variant in the 20-pin QFN package, distinguishing it from lower memory options or different package types within the same product line.

Replacement Considerations

Consult the official datasheet Table 1.1 for recommended substitutes within the C8051F52x/F53x family. Verify pinout compatibility and memory size equivalence when considering alternative part numbers. No direct public substitute part numbers are explicitly listed in the provided source material for cross-referencing.
