C8051T602-GMR

Overview

The C8051T602-GMR is a mixed-signal microcontroller from Silicon Labs, featuring an 8-bit CIP-51 core with pipelined architecture. It includes 4 kB of byte-programmable EPROM and 256 bytes of internal data RAM. The device integrates a 10-bit ADC supporting up to 500 ksps conversion rates and up to 8 external inputs. Operating voltage ranges from 1.8 V to 3.6 V, with an operating temperature range of -40 °C to +85 °C. It utilizes a 3 x 3 mm QFN11 package.

Feature Summary

• Features a high-speed 8051 core executing 70% of instructions in one or two system clocks for efficient processing.
• Includes on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging with breakpoints and memory inspection.
• Integrates analog peripherals such as a 10-bit ADC with programmable window detector and a low-current comparator.
• Supports hardware-enhanced UART and SMBus serial ports alongside three general-purpose 16-bit counter/timers.

Applications

• Embedded systems requiring byte-programmable EPROM for field upgrades
• Applications needing onboard analog-to-digital conversion with temperature sensing
• Industrial control environments utilizing SMBus or UART communication
• Battery-powered devices benefiting from low-voltage operation and power management modes

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package type and temperature rating. Check for current lifecycle status, as this model may be marked Not Recommended for New Designs. Ensure ESD handling protocols are followed during storage and assembly to prevent damage to the sensitive CMOS components.

Selection Notes

Select this component when byte-programmable EPROM is required instead of Flash memory. Consider the integrated 10-bit ADC and comparator if analog signal conditioning is needed without external chips. Evaluate the 1.8 V to 3.6 V supply range against system power constraints. Review pinout compatibility if replacing existing designs using the QFN11 package.
