CY8C21434-24LTXIKS

Overview

The CY8C21434-24LTXI is an 8-bit microcontroller from the PSoC family, featuring an M8C core and operating at a maximum frequency of 24 MHz. It includes 8 kB of Flash program memory and 512 bytes of SRAM. The device provides 28 I/O pins and integrates one 10-bit Delta-Sigma ADC with a sampling rate of 5.9 ksps. It supports CapSense technology for touch sensing applications. The component operates within a voltage range of 2.4 V to 5.25 V and functions in temperatures from -40 °C to 85 °C, housed in a QFN-32 package.

Feature Summary

Integrates CapSense Plus technology for capacitive touch sensing capabilities
Includes a programmable mixed-signal array with a Delta-Sigma ADC
Features an 8-bit M8C processor core for embedded control

Applications

Capacitive touch interface designs
Low-power embedded control systems
Battery-operated devices requiring mixed-signal processing

Procurement Notes

Verify the specific suffix 'KS' against official Infineon documentation, as standard datasheets typically list 'CY8C21434-24LTXI'. Confirm that the suffix does not indicate a non-standard variant or special qualification. Ensure the source document explicitly identifies this exact part number to avoid substitution errors with the standard commercial grade version.

Selection Notes

Select this component when a design requires integrated capacitive touch sensing alongside basic analog-to-digital conversion. The 24 MHz clock speed and 8 kB memory are suitable for moderate complexity control tasks. Verify that the QFN-32 package fits the board space constraints and that the 2.4 V to 5.25 V supply range matches the system power architecture.

Part Context

This part belongs to the Cypress (now Infineon) PSoC 2100 series, which combines digital and analog peripherals on a single chip. The CY8C214xx series specifically targets cost-sensitive applications needing touch sensing. The M8C core provides efficient code execution for simple control loops while the programmable interconnect allows flexible peripheral configuration.
