C8051T603-GM

Overview

The C8051T603-GM is a mixed-signal microcontroller featuring an 8051 core with up to 25 MHz clock speed and 25 MIPS throughput. It includes 1.5 kB byte-programmable EPROM code memory and 256 Bytes internal data RAM. The device operates on a supply voltage of 1.8 to 3.6 V and supports a temperature range of –40 to +85 °C. Digital peripherals include three general purpose 16-bit counter/timers, a 16-bit programmable counter array (PCA) with three capture/compare modules, hardware-enhanced UART, and SMBus serial ports. Analog features consist of a comparator with programmable hysteresis and response time.

Feature Summary

• Features a high-speed pipelined 8051 core executing 70% of instructions in one or two system clocks.
• Includes on-chip debug circuitry for full-speed, non-intrusive in-system debugging with breakpoints and single stepping.
• Integrates a programmable internal high-frequency oscillator with ±2% accuracy supporting crystal-less UART operation.
• Provides a priority crossbar decoder allowing flexible assignment of port I/O pins to analog and digital functions.

Applications

• Battery chargers
• Electronic toys and games
• Motor control systems
• Optical communications

Procurement Notes

Verify the component status before procurement as the datasheet explicitly states this series is Not Recommended for New Designs. Confirm that the specific ordering suffix matches the required package type, such as QFN11 or SOIC14, as availability varies by variant. Ensure design constraints accommodate the specified operating voltage and temperature ranges.

Selection Notes

Select this MCU for applications requiring byte-programmable EPROM and integrated analog peripherals in a compact form factor. The C8051T603-GM lacks the 10-bit ADC found in other variants like the T600 or T602, relying instead on the onboard comparator. Consider the available communication interfaces and timer configurations against project requirements.

Part Context

This component belongs to the C8051T60x family of mixed-signal microcontrollers from Silicon Labs. The family shares a common architecture but differs in memory size and peripheral inclusion. The C8051T603-GM specifically utilizes the QFN11 or SOIC14 package options within this lineup.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material.

FAQ
