CG8634AM

Overview

The CG8634AM is a 32-bit microcontroller unit (MCU) belonging to the Infineon PSOC™ 4 CY8C4100 family. It integrates an ARM® Cortex®-M0 processor core operating at a maximum frequency of 24 MHz. The device features 32 KB of in-system programmable flash memory and includes a Programmable System-on-Chip architecture that allows for customizable analog and digital peripheral blocks. It is housed in a 44-TQFP package with dimensions of 10x10 mm, designed for embedded control applications requiring mixed-signal processing capabilities.

Feature Summary

• Integrates an ARM Cortex-M0 processor core for efficient code execution
• Features Programmable System-on-Chip (PSoC) architecture for customizable analog and digital peripherals
• Includes in-system programmable flash memory for flexible firmware updates

Applications

• Embedded control systems
• Mixed-signal signal processing applications
• General-purpose microcontroller tasks in consumer electronics

Procurement Notes

Verify the exact ordering suffix and package variant when sourcing, as manufacturers often use suffixes to denote temperature ranges or tape-and-reel specifications. Confirm the component status, as some listings may indicate obsolete stock. Ensure compatibility with your PCB footprint for the 44-TQFP package. Request official datasheets to validate pin configurations and electrical characteristics against your design requirements before finalizing procurement.

Selection Notes

Select this component when a low-power 32-bit MCU with customizable analog capabilities is required. The PSOC 4 architecture offers flexibility in routing internal signals, reducing external component count. Consider the 24 MHz clock speed and 32 KB memory size for application complexity. Evaluate the 44-pin TQFP package constraints against board space limitations. Compare power consumption metrics in active and sleep modes against alternative MCUs in the same performance class.

Part Context

The CG8634AM is part of the Infineon PSoC 4 CY8C4100 series, which targets cost-sensitive embedded applications. This family combines a standard ARM Cortex-M0 core with unique programmable analog blocks. It serves as a bridge between simple 8/16-bit controllers and more complex high-performance MCUs, offering significant integration benefits for mixed-signal designs without the need for separate analog ICs.

Replacement Considerations

Check for direct cross-reference part numbers within the PSoC 4 family, such as other CY8C41xx variants with similar memory and pin counts. Verify if newer generation PSoC 4000S or PSoC 4200 devices offer compatible pinouts and enhanced features. Ensure any substitute maintains the same ARM Cortex-M0 core instruction set compatibility.
