• Integrates a high-speed 8051 CPU core with pipelined architecture for efficient instruction processing.
• Includes a 10-bit analog-to-digital converter with programmable window detection capabilities.
• Features byte-programmable EPROM for flexible in-system reprogramming and non-volatile storage.
• Provides integrated communication ports including UART and SMBus with hardware support.

Applications

• Battery-powered sensor nodes requiring low power consumption
• Industrial control systems utilizing SMBus or UART connectivity
• Data acquisition applications involving analog signal monitoring

Procurement Notes

Verify that the specific part number matches the required package variant, as the C8051T60x series offers multiple options such as QFN-11 and SOIC-14. Confirm that the design accommodates the Not Recommended for New Designs status by Silicon Laboratories. Ensure compatibility with existing development tools and debug interfaces before finalizing procurement decisions.

Selection Notes

Select this component when a compact mixed-signal solution with EPROM flexibility is required. The C8051T604-GM is suitable for designs needing a 10-bit ADC and standard serial interfaces without USB integration. Consider the limited pin count and memory size against application requirements. Evaluate the transition strategy given the manufacturer's recommendation against new designs.

Part Context

This device belongs to the C8051T60x series of mixed-signal microcontrollers manufactured by Silicon Laboratories. The series is characterized by its byte-programmable EPROM technology and high-speed 8051 cores. It serves as a standalone system-on-a-chip solution integrating analog and digital peripherals into small form factor packages.

Replacement Considerations

Silicon Laboratories explicitly marks the C8051T60x series as Not Recommended for New Designs. No direct public substitute part numbers are listed in the documentation; engineers should evaluate newer families such as the C8051F or EFM8 series for future projects.
