C8051F901-D-GUR

Overview

The C8051F901-D-GUR is an 8-bit microcontroller from Silicon Labs, part of the C8051F9xx series. It features a high-speed CIP-51 core operating at up to 25 MHz with 25 MIPS throughput. The device includes 8 kB of in-system programmable Flash memory and 768 bytes of RAM. Key peripherals include a 10-bit SAR ADC with up to 300 ksps throughput, two comparators, and a SmaRTClock real-time clock. It supports supply voltages from 0.9 V to 3.6 V and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with sleep modes as low as 10 nA and fast wake-up times
• Integrated 10-bit analog-to-digital converter with programmable throughput and on-chip voltage reference
• Built-in DC-DC converter enabling operation from a single battery cell down to 0.9 V
• Comprehensive digital peripheral set including hardware SMBus, dual SPI, and UART interfaces

Applications

• Single-cell or dual-cell battery-powered instrumentation
• Low-power industrial control systems requiring precise timing
• Portable medical devices utilizing capacitive touch sensing
• Smart sensors with integrated temperature monitoring

Procurement Notes

Verify the specific suffix 'D' against the manufacturer's official documentation to confirm package type and temperature grade variations. Confirm current availability status as distribution channels may list end-of-life or limited stock items. Ensure the ordering code matches the exact pinout and memory configuration required for your design implementation.

Selection Notes

Select this component when designing for extreme low-power constraints requiring sub-microampere sleep currents. The integrated DC-DC converter makes it suitable for applications powered by a single lithium cell. Consider the 10-bit ADC resolution and available analog inputs if signal conditioning is needed without external components.

Part Context

This device belongs to the C8051F9xx family of mixed-signal microcontrollers designed for ultra-low power applications. It shares architectural similarities with the C8051F91x series but offers reduced Flash memory capacity. The family emphasizes energy efficiency through advanced power management modes and efficient clocking structures.

Replacement Considerations

C8051F902-GU: Offers identical functionality with 16 kB Flash instead of 8 kB. C8051F911-GU: Provides 16 kB Flash and similar performance characteristics. Verify pin compatibility and software register mapping before substitution.
