C8051F855-C-IUR

Overview

The C8051F855-C-IUR is an 8-bit microcontroller from the Silicon Labs C8051F85x family, featuring a high-speed CIP-51 core operating at up to 25 MHz. It integrates 2 kB of in-system programmable Flash memory and 256 bytes of RAM within a 24-pin QSOP package. The device includes a 12-bit ADC with up to 16 channels, two analog comparators, and multiple communication interfaces including UART, I2C/SMBus, and SPI.

Feature Summary

High-Speed CIP-51 Core: Pipelined architecture delivering up to 25 MIPS throughput with standard 8051 instruction set compatibility.
On-Chip Debug Circuitry: Facilitates full-speed, non-intrusive in-system debugging without requiring external emulators.
Integrated Analog Peripherals: Features a 12-bit ADC with up to 16 input channels and two low-current analog comparators.
Communication Interfaces: Equipped with UART, I2C/SMBus, and SPI modules for versatile data exchange capabilities.

Applications

Battery-powered devices requiring low-power operation
Industrial control systems utilizing robust I/O features
Consumer electronics applications needing compact form factors

Procurement Notes

Verify the specific suffix 'IUR' against official ordering guides to confirm temperature range and packaging details. Confirm component status as this family may be marked not recommended for new designs. Ensure compatibility with existing design constraints before procurement.

Selection Notes

Select this model when a cost-effective 8-bit solution with integrated analog peripherals is required. Consider the 2 kB Flash limit for application size. Evaluate the 24-pin QSOP package availability against board space requirements compared to QFN or SOIC options.

Part Context

Part of the C8051F85x/86x low-cost MCU family offering mixed-signal integration. Designed for applications balancing performance and cost, providing essential digital and analog functions on a single chip suitable for embedded control tasks.
