C8051F396-A-GM

Overview

The C8051F396-A-GMR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F39x family, featuring a pipelined 8051 core with up to 50 MIPS throughput at a 50 MHz clock. It integrates 16 kB of in-system programmable Flash memory and 1 kB of internal data RAM. The device includes analog peripherals such as a 10-bit ADC with up to 500 ksps throughput, two 10-bit current output DACs, and a precision temperature sensor accurate to ±2 °C. Digital interfaces include UART, SMBus (I²C compatible), SPI, six timers, and a Programmable Counter Array. It operates on a 1.8 V to 3.6 V supply and supports an extended temperature range of –40 °C to +105 °C in a 20-pin QFN package.

Feature Summary

• Integrated high-speed 8051 core with pipelined architecture for efficient instruction execution
• On-chip mixed-signal capabilities including 10-bit ADC, dual 10-bit DACs, and calibrated temperature sensor
• Comprehensive digital peripheral set with multiple serial communication ports and timer modules
• Supports low-power operation with Stop mode current consumption and flexible clock source switching

Applications

• Industrial control systems requiring precise analog signal acquisition
• Battery-powered devices utilizing low-power modes and internal oscillators
• Embedded applications needing in-circuit reprogrammable firmware storage
• Sensor interface circuits leveraging integrated comparators and temperature sensing

Procurement Notes

Verify the specific suffix 'GMR' indicates tape-and-reel packaging when ordering. Confirm that the component is marked as Not Recommended for New Designs in official documentation to assess long-term availability risks. Ensure compatibility with existing design infrastructure before procurement due to potential obsolescence status.

Selection Notes

Select this component for designs requiring footprint compatibility with the legacy C8051F33x series while needing higher performance. Consider the extended temperature range if operating in harsh environments. Evaluate the available GPIO count against interface requirements, noting that this variant provides 17 I/O pins compared to other family members.

Part Context

This part belongs to the C8051F39x family, which serves as a next-generation upgrade to the C8051F33x series. It maintains hardware and code compatibility while offering increased speed, additional RAM, and expanded feature sets. The family is characterized by its system-on-a-chip integration, reducing external component counts for mixed-signal applications.

Replacement Considerations

Direct substitutes within the same family include C8051F392, C8051F394, C8051F397, C8051F398, and C8051F399, which share identical pinouts and core functionality but differ in Flash memory size or EEPROM presence.
