C8051F855-C-IU

Overview

The C8051F855-C-IU is an 8-bit microcontroller from the Silicon Labs C8051F85x family, featuring a CIP-51 core with up to 25 MHz throughput. It includes 2 kB of in-system programmable Flash memory and 256 bytes of RAM. The device operates within a supply voltage range of 2.2 V to 3.6 V and supports industrial temperatures from -40 °C to +125 °C. It provides 18 I/O pins in a QSOP-24 package, along with UART, I2C/SMBus, and SPI interfaces.

Feature Summary

High-speed CIP-51 core delivering up to 25 MIPS throughput
On-chip debug circuitry for non-intrusive in-system debugging
Crossbar-enabled general-purpose I/O with 5 V tolerance
Integrated analog comparators with programmable hysteresis

Applications

Industrial control systems
Sensor signal processing
Motor control applications
Battery-powered devices requiring low power modes

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Review the latest errata sheet for any revision-specific behavioral notes. Ensure storage conditions meet humidity requirements to prevent package damage during soldering processes.

Selection Notes

Select this model when 2 kB of program memory suffices for the application logic. Choose the -IU suffix specifically for industrial temperature range requirements (-40 °C to +125 °C). Verify that the QSOP-24 package dimensions fit the target PCB layout constraints. Consider the absence of an on-chip ADC if analog-to-digital conversion is required externally.

Part Context

This component belongs to the C8051F85x/86x low-cost 8-bit MCU family. These devices are designed as system-on-chip solutions integrating mixed-signal peripherals. The family emphasizes high integration to reduce external component count. Documentation indicates these parts are not recommended for new designs.
