C8051F853-C-IUR

Overview

The C8051F853-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 8 kB of in-system programmable Flash memory and 512 bytes of RAM. 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. It operates within a supply voltage range of 2.2 V to 3.6 V and supports industrial temperature ranges.

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 programmable analog comparators.
• Flexible Clocking System: Includes calibrated internal high-frequency (24.5 MHz) and low-frequency (80 kHz) oscillators.

Applications

• Industrial control systems requiring robust 8-bit processing
• Sensor interface modules utilizing integrated ADC capabilities
• Embedded applications needing on-chip debug and low power modes

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against QSOP-24 specifications. Ensure storage conditions comply with moisture sensitivity level requirements prior to reflow soldering processes.

Selection Notes

Select this component for designs prioritizing code compatibility with legacy 8051 architectures while requiring modern mixed-signal integration. Evaluate peripheral needs against the specific 8 kB Flash and 512 Byte RAM constraints. Consider the -I suffix for industrial temperature range requirements over commercial alternatives.
