• Includes mixed-signal peripherals such as a 12-bit analog-to-digital converter and comparators.
• Features flexible I/O crossbar architecture allowing dynamic pin assignment.
• Supports low-power operation modes with watchdog timer and power-on reset.

Applications

• Industrial control systems requiring mixed-signal processing
• Medical instrumentation devices
• Smart metering applications
• Sensor interface modules

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm stepping or revision differences. Confirm package marking and RoHS compliance status through official documentation before procurement. Ensure design-in compatibility with existing toolchains and development environments.

Selection Notes

Select this part when a balance of moderate Flash capacity and rich analog peripherals is required. Compare against C8051F3xx series for similar performance with different peripheral sets. Consider pin count and package availability relative to board layout constraints. Verify operating temperature range requirements against industrial specifications.

Part Context

This component belongs to the C8051F family of fully integrated mixed-signal microcontrollers. These devices are known for combining a fast 8051 CPU with extensive on-chip resources, reducing external component count. The series targets applications needing precise analog control alongside digital processing capabilities.

Replacement Considerations

Check for direct substitutes within the C8051F96x variant group. Evaluate C8051F3xx series parts for functional equivalence if pinout compatibility allows. Consult official obsolescence notices for potential end-of-life status.
