C8051F507-IQR

Overview

The C8051F507-IQR is an 8-bit mixed-signal ISP Flash MCU from the C8051F50x family, featuring a high-speed pipelined 8051 core with up to 50 MIPS throughput at a 50 MHz clock. 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 supporting up to 200 ksps, two comparators, and multiple digital peripherals including CAN 2.0, LIN 2.1, UART, SMBus, and SPI. It operates on a supply voltage of 1.8 V to 5.25 V and is available in a 32-pin QFN package.

Feature Summary

• High-performance 8051 core with pipelined architecture executing 70% of instructions in one or two system clocks
• Integrated on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
• Mixed-signal capabilities with a 12-bit ADC, built-in temperature sensor, and programmable voltage comparators
• Automotive qualified with AEC-Q100 compliance and operation across a wide temperature range

Applications

• Automotive embedded systems requiring CAN and LIN communication
• Industrial control applications needing precise analog signal acquisition
• Smart metering devices utilizing low-power stop modes
• Sensor interfaces integrating temperature monitoring and threshold detection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Confirm that the component status aligns with project lifecycle requirements, as this series may be designated for limited production or obsolescence. Ensure compatibility with existing development tools and debug adapters before finalizing procurement orders.

Selection Notes

Select this model when a compact 32-pin form factor is required alongside robust automotive-grade reliability. It is suitable for designs needing integrated CAN and LIN controllers without external transceivers. Consider the 12-bit ADC resolution and 200 ksps speed for applications demanding accurate real-time analog monitoring within a constrained power budget.

Part Context

This component belongs to the C8051F50x/F51x mixed-signal ISP Flash MCU family by Silicon Laboratories. The family shares a common CIP-51 core and peripheral set, differing primarily in memory size and pin count. The C8051F507 variant specifically offers 32 kB Flash and is housed in a 32-pin package, providing a balance of integration and I/O availability for space-constrained embedded designs.

Replacement Considerations

Pin-for-pin compatible alternatives within the same family include the C8051F500, C8051F501, C8051F504, and C8051F505, which utilize larger packages. For direct functional substitution in a 32-pin footprint, verify cross-compatibility with other C8051F50x variants having equivalent memory configurations.
