C8051F507-IQ

Overview

The C8051F507-IQ is an automotive-grade, mixed-signal ISP Flash MCU from the Silicon Labs C8051F50x family. It features a high-speed 8051 core operating at up to 50 MIPS with a 50 MHz clock. The device integrates 32 kB of in-system programmable Flash memory and 4.25 kB of internal data RAM (256 bytes + 4096 bytes XRAM). Key peripherals include a 12-bit ADC supporting up to 200 ksps, two comparators, CAN 2.0 and LIN 2.1 controllers, UART, SMBus, and SPI interfaces. It operates on a supply voltage of 1.8 V to 5.25 V and is housed in a 32-pin QFN package.

Feature Summary
