C8051F411-GM

Overview

The C8051F411-GM is a mixed-signal microcontroller from the C8051F41x family, featuring an 8051 core with up to 50 MHz operation. It integrates 32 kB of Flash memory and 2.3 kB of RAM within a 28-pin QFN package. Key analog peripherals include a 24-channel 12-bit ADC and dual 12-bit DACs. The device supports a supply voltage range of 2.0 V to 5.25 V and operates between -40°C and +85°C.

Feature Summary

• Integrates a high-performance pipelined 8051 core capable of executing most instructions in one or two system clocks for improved throughput.
• Features a comprehensive analog subsystem including a 24-channel 12-bit ADC with programmable throughput and dual 12-bit current-mode DACs.
• Includes smaRTClock technology providing a real-time clock with battery-backed RAM and a backup voltage regulator for low-power timekeeping.
• Supports non-intrusive on-chip debug via the C2 interface, allowing full-speed debugging without external emulators.

Applications

• Voice recording circuits utilizing hardware accumulation and burst mode features for audio processing
• Portable instruments requiring high-precision analog-to-digital conversion
• Data acquisition systems needing multiple simultaneous analog inputs
• Battery-powered devices leveraging smaRTClock for extended standby capabilities

Procurement Notes

Verify component status before design finalization as this part is marked Not Recommended for New Designs. Confirm that the specific QFN-28 package variant matches your PCB footprint requirements. Ensure compatibility with existing firmware architectures given the enhanced CIP-51 instruction set compared to standard 8051 cores.

Selection Notes

Select this component when a small form factor MCU with extensive analog integration is required. The C8051F411-GM offers a balance of processing speed and peripheral density suitable for applications where board space is limited but signal conditioning is necessary. Consider the available I/O count and memory size relative to application complexity.
