CY8C21634-24LTXIT

Overview

The CY8C21634-24LTXIT is a PSoC Low Power Programmable System-on-Chip from Infineon Technologies, featuring an 8-bit CPU core integrated with analog and digital peripheral blocks. It operates at a maximum frequency of 24 MHz and includes 32 KB of Flash memory, 1 KB of SRAM, and 512 bytes of EEPROM. The device supports multiple low-power modes including Active, Idle, Sleep, and Deep Sleep to optimize energy consumption for battery-powered applications.

Feature Summary

• Integrates programmable analog and digital blocks on a single chip for flexible system design
• Supports multiple low-power operating modes to extend battery life in portable devices
• Includes built-in non-volatile memory for data retention without external components

Applications

• Battery-powered consumer electronics
• Industrial control systems requiring low power consumption
• Smart home automation devices

Procurement Notes

Verify the exact suffix LTXIT corresponds to the specific package type and temperature range required for your application. Confirm RoHS compliance status through official Infineon documentation or authorized distributors before procurement. Ensure ESD handling procedures are followed during assembly.

Selection Notes

Select this component when a mixed-signal microcontroller with programmable analog capabilities is needed. Consider the 24 MHz speed limit and memory sizes against application requirements. Evaluate power consumption across different modes if battery efficiency is critical.

Part Context

This part belongs to the PSoC 1 family, which combines a standard 8051-compatible CPU with configurable analog and digital peripherals. It allows designers to replace multiple discrete components with a single chip, reducing board space and complexity compared to traditional MCU solutions.

Replacement Considerations

Check Infineon's official obsolescence notices. Potential substitutes may include other PSoC 1 variants with similar pinouts or upgraded families like PSoC 3/4/5LP, though architectural differences require redesign.
