C8051F019-GQR

Overview

The C8051F019-GQR is an 8-bit microcontroller from the Silicon Labs C8051F01x family, featuring a high-speed 25MHz CMOS MCU core. It integrates 16KB of in-system programmable Flash memory and operates within a voltage range of 2.7V to 3.6V. The device includes 10-channel 10-bit analog-to-digital converters and supports multiple communication interfaces including SPI, I2C, and UART. Packaged in a 48-pin TQFP with a 7x7mm footprint, it functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a fully static 8051-compatible core with on-chip Flash for in-system programming.
• Includes mixed-signal peripherals such as 10-bit ADCs and programmable counters/array.
• Supports standard serial communication protocols via dedicated hardware modules.
• Features internal oscillator options and comprehensive power management modes.

Applications

• Battery-powered sensor nodes requiring low power consumption
• Industrial control systems with analog signal processing needs
• Embedded devices utilizing serial communication interfaces

Procurement Notes

Verify the complete part number including the suffix to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status and check for any recent Product Change Notices regarding assembly or material updates. Ensure compatibility with existing design-in tools and debug adapters specific to the C8051F series architecture.

Selection Notes

Select this component when an 8-bit architecture suffices for application logic while requiring integrated analog conversion capabilities. Consider the 48-pin TQFP package constraints for PCB layout. Evaluate if the 16KB Flash capacity meets code storage requirements and if the 25MHz speed aligns with real-time processing demands compared to higher-performance variants.

Part Context

This part belongs to the C8051F01x series of fully integrated mixed-signal microcontrollers. It shares architectural similarities with other members like the C8051F018 but offers specific peripheral configurations tailored for cost-sensitive embedded applications. The series emphasizes single-chip solutions by combining digital processing with essential analog functions.

Replacement Considerations

Check for direct pin-compatible upgrades within the C8051F01x family. Verify functional equivalence of peripheral sets before substituting with different series members. Consult official documentation for any known errata or recommended design changes associated with newer revisions.
