C8051F005

Overview

The C8051F005 is a fully integrated mixed-signal System-on-Chip microcontroller from Silicon Labs. It features a high-speed 8051-compatible core operating at up to 25 MHz with 25 MIPS throughput. The device includes 32 KB of in-system programmable Flash memory and 2,304 bytes of internal RAM. Key analog peripherals consist of an 8-channel 12-bit ADC with a programmable gain amplifier, two 12-bit DACs, and two voltage comparators. Digital interfaces include hardware SMBus, SPI, and UART. The unit operates on a supply voltage between 2.7 V and 3.6 V within a temperature range of -40°C to +85°C.

Feature Summary

• High-performance pipelined CIP-51 CPU executes 70% of instructions in one or two system clock cycles for efficient processing.
• Integrated 12-bit SAR ADC supports up to 100 ksps throughput with programmable gain amplifier and data-dependent windowed interrupt generation.
• On-chip JTAG debug circuitry enables full-speed, non-intrusive in-system debugging without requiring external emulation hardware.
• Hardware serial ports including SMBus, SPI, and UART are available concurrently for flexible digital communication.

Applications

• Aeronautical AC parameter measurement instruments
• Data acquisition systems requiring precise signal processing
• Embedded control applications utilizing onboard analog peripherals

Procurement Notes

Verify the specific package variant (TQFP-64) against design requirements. Confirm that the component status aligns with long-term production plans as availability may vary. Ensure development tools support the C8051F00x family for programming and debugging. Validate power supply constraints match the specified 2.7V to 3.6V operational range.

Selection Notes

Select this model when a complete mixed-signal solution is required without external components. The 2,304-byte RAM distinguishes it from lower-capacity variants like the F000. Choose this part if 12-bit resolution is mandatory for analog inputs. Verify that the 25 MHz maximum frequency meets real-time processing demands.

Part Context

This component belongs to the C8051F00x series of mixed-signal MCUs. It shares the same core architecture and peripheral set as the F000, F001, F002, F006, and F007 models. The primary differentiator is the increased internal RAM size of 2,304 bytes compared to the 256 bytes found in other series members.

Replacement Considerations
