C8051T627-B-GM

Overview

The C8051T627-B-GM is a high-performance 8-bit microcontroller from Silicon Labs, featuring a CIP-51 core with up to 48 MIPS throughput at a 48 MHz clock speed. It integrates 64 kB of byte-programmable EPROM and up to 3328 bytes of internal data RAM. The device includes a Full Speed USB 2.0 function controller with an integrated transceiver and 1 kB buffer memory. Analog peripherals consist of a 10-bit ADC supporting up to 500 ksps conversion rates and two comparators. Supply voltage ranges from 1.8 V to 5.25 V, and the operating temperature spans -40 °C to +85 °C.

Feature Summary

• Integrates a Full Speed USB 2.0 function controller with an on-chip transceiver and clock recovery, eliminating the need for external components.
• Features a high-speed pipelined CIP-51 core capable of executing 70% of instructions in one or two system clocks for efficient processing.
• Includes a 10-bit analog-to-digital converter (ADC) with up to 21 external inputs and a built-in temperature sensor.
• Supports in-application programming of EPROM memory via firmware, allowing for field updates without external programmers.

Applications

• USB-enabled peripheral devices
• Data acquisition systems requiring analog input
• Industrial control interfaces
• Battery-powered applications utilizing low-power modes

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the QFN variant requires specific handling procedures. Ensure compatibility with existing design specifications regarding supply voltage and thermal management before integration into final assemblies.

Selection Notes

Select this model when USB connectivity and analog signal processing are required within a single chip. Consider the 64 kB EPROM capacity for code storage needs and verify that the 10-bit ADC resolution meets application accuracy requirements. Evaluate power consumption profiles against available internal oscillators for battery-operated designs.

Part Context

This component belongs to the C8051T62x/32x family of mixed-signal microcontrollers. It shares architectural similarities with other members like the C8051T620 and C8051T626, differing primarily in memory size and peripheral availability. The family utilizes the CIP-51 architecture, offering enhanced performance over traditional 8051 cores while maintaining software compatibility.

Replacement Considerations

Consult official documentation for end-of-life notices. Verify pinout and register compatibility if substituting with other C8051T6xx series variants. Ensure any replacement supports the required USB functionality and EPROM programming capabilities.
