C8051F336-GMR

Overview

The C8051F336-GMR is a mixed-signal System-on-a-Chip microcontroller from Silicon Labs, featuring a high-speed pipelined 8051-compatible core operating at up to 25 MIPS with a 25 MHz clock. It integrates 16 kB of in-system programmable Flash memory and 768 bytes of internal data RAM. The device includes a true 10-bit ADC supporting up to 200 ksps with an analog multiplexer for up to 20 external single-ended or differential inputs, alongside a 10-bit current output DAC. Digital peripherals include hardware-enhanced UART, SMBus/I2C, and SPI interfaces, four general-purpose 16-bit timers, and a Programmable Counter Array. It operates on a supply voltage of 2.7 V to 3.6 V within a temperature range of –40 °C to +85 °C.

Applications

• Data acquisition systems requiring multi-channel analog signal processing
• Industrial control applications utilizing mixed-signal capabilities
• Embedded systems needing integrated USB-free connectivity via standard serial protocols
• Battery-powered devices leveraging low-power suspend modes and internal oscillators

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors or certified partners. Confirm the specific package variant (QFN-20 or QFN-24) matches design requirements, as pinouts differ between versions. Check for updated revision levels against the latest datasheet to ensure compatibility with existing firmware. Validate that the 'Not Recommended for New Designs' status aligns with long-term maintenance plans for existing products.

Selection Notes

Select this component when a fully integrated mixed-signal solution is required without external ADC/DAC components. Consider the C8051F33x family for its pin-compatibility with the C8051F330 series if upgrading legacy designs. Evaluate the 10-bit resolution and 200 ksps speed against application bandwidth needs. Ensure the 2.7 V to 3.6 V supply range fits the system power architecture and that the 25 MIPS performance meets real-time processing constraints.

Part Context

The C8051F336-GMR belongs to the C8051F33x family of byte-programmable EPROM MCUs. This series is designed for high-performance embedded applications requiring significant on-chip analog and digital resources. It shares architectural similarities with other members like the C8051F337, F338, and F339, differing primarily in memory size and peripheral availability. The GMR suffix indicates a specific tape-and-reel packaging option suitable for automated surface-mount assembly processes.
