Overview
The C8051F996-C-GDI is an 8-bit microcontroller from Silicon Labs, belonging to the C8051F9xx series. It features a CIP-51 core operating at up to 25 MHz. The device integrates 32 kB of in-system programmable Flash memory and 2.5 kB of RAM. Key peripherals include a 17-channel 12-bit ADC, a 12-bit DAC, and multiple communication interfaces such as SPI, I2C, and UART. It operates within a voltage range of 1.8 V to 3.6 V and supports industrial temperature ranges.
Feature Summary
- Integrates high-resolution analog peripherals including a 17-channel 12-bit ADC and a 12-bit DAC for precise signal conditioning.
- Supports in-system programming via standard debug interfaces for efficient firmware updates and development.
- Combines mixed-signal capabilities with digital control functions on a single chip to reduce system component count.
Applications
- Battery-powered sensor nodes requiring low power consumption and high precision analog measurement.
- Industrial data acquisition systems utilizing integrated ADC/DAC functionality.
- Embedded control applications in medical instrumentation or environmental monitoring devices.
Procurement Notes
Verify the specific suffix 'GDI' against the manufacturer's current datasheet to confirm package type and moisture sensitivity level. Ensure compatibility with existing PCB footprints, as packaging variations may exist within the same part number family. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into regulated assemblies.
Selection Notes
Select this component when a mixed-signal MCU with integrated high-resolution ADC and DAC is required. The CIP-51 core offers deterministic execution suitable for real-time control loops. Consider the 32 kB Flash capacity for complex firmware requirements. Evaluate power supply constraints against the 1.8 V to 3.6 V operating range to ensure stable performance across the intended application environment.
Part Context
This part belongs to the C8051F9xx series of fully integrated mixed-signal microcontrollers. These devices are designed to replace discrete analog and digital components, simplifying board design. The series is characterized by its high-speed 8051-compatible core combined with extensive on-chip analog peripherals and digital interconnects.
Replacement Considerations
Check for direct pin-to-pin replacements within the C8051F9xx family, such as the C8051F98x series, which may offer similar peripheral sets with different memory sizes. Verify software compatibility if migrating between variants, as register configurations may differ slightly.
