CY8C21634-24LTXIKA

Overview

The CY8C21634-24LTXIKA is an 8-bit microcontroller unit (MCU) belonging to the PSoC 1 family, manufactured by Cypress Semiconductor. It integrates an M8C core operating at a maximum frequency of 24 MHz with 8 KB of in-system programmable flash memory and 512 bytes of RAM. The device features a 32-pin QFN package measuring 5x5 mm. It supports a supply voltage range of 2.4 V to 5.25 V and operates within a temperature range of -40°C to +85°C.

Feature Summary

Integrates configurable analog and digital peripherals within a single chip architecture.
Supports CapSense touch sensing capabilities for user interface applications.
Includes built-in USB connectivity for communication interfaces.

Applications

Capacitive touch sensing controllers
USB-enabled embedded devices
Industrial control systems
Consumer electronics

Procurement Notes

Verify the specific suffix 'IKA' against official Cypress/Infineon documentation to confirm pinout compatibility and electrical characteristics. Ensure the component matches the standard CY8C21634B series specifications if cross-referencing with generic datasheets. Confirm RoHS compliance status directly from the manufacturer's declaration.

Selection Notes

Select this component when an 8-bit MCU with integrated USB and analog configurability is required. The 24 MHz speed and 8 KB flash are suitable for moderate complexity firmware. Consider the 32-pin QFN package constraints for PCB layout. Verify that the 2.4V to 5.25V supply range aligns with the system power design.

Part Context

This part belongs to the PSoC 1 CY8C21xxx series, which combines a fast 8-bit processor with programmable analog blocks. The series is designed to reduce external component count by integrating mixed-signal functions. Cypress Semiconductor was acquired by Infineon Technologies, affecting long-term support channels.

Replacement Considerations

Check for CY8C21634B-24LTXI as a potential equivalent. Verify package dimensions and pin assignments before substitution. Confirm software compatibility with the M8C core architecture.
