Overview
The C8051F996-GUR is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, featuring a CIP-51 core operating at up to 25 MHz. It integrates 32 KB of in-system programmable Flash memory and 2 KB of RAM. The device includes a 12-bit ADC with 16 channels, a 12-bit DAC, and multiple digital peripherals such as SPI, I2C/SMBus, and UART/USART interfaces. It supports operation within a voltage range of 1.8 V to 3.6 V and is housed in a 24-pin QSOP package.
Feature Summary
- Integrates a high-speed CIP-51 core compatible with standard MCS-51 instruction sets for efficient code execution.
- Includes mixed-signal capabilities with a 12-bit ADC and DAC for precise analog signal processing.
- Supports non-invasive full-speed in-system programming and debugging via JTAG or C2 interface.
Applications
- Wireless sensor nodes requiring low power consumption
- Industrial monitoring systems utilizing temperature sensing
- Battery-powered devices needing efficient power management
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Review official datasheets for specific handling requirements and storage conditions to ensure long-term reliability in final applications.
Selection Notes
Select this model when a robust 8-bit MCU with integrated mixed-signal peripherals is required. Ensure the application benefits from the CIP-51 architecture's speed and the extensive on-chip resources. Verify that the 24-pin QSOP package fits the design constraints and that the voltage range matches the system power supply.
Part Context
Part of the C8051F9xx family, designed for cost-effective embedded control. This series emphasizes high integration by combining processing, memory, and analog functions on a single chip, reducing external component count and board space compared to traditional discrete solutions.
Replacement Considerations
Consult official documentation for verified substitute part numbers. Cross-referencing should be limited to components explicitly listed as compatible replacements by the manufacturer to ensure functional equivalence.
