Product details

What this PSoC 1 brings to the board

The Infineon CY8C24423A-24LTXIT is an 8-bit PSoC 1 microcontroller built around the M8C core clocked at 24 MHz. It packs 4 KB of Flash and 256 x 8 bytes of RAM, plus a 10-channel 14-bit ADC and a 2-channel 9-bit DAC on-chip — mixed-signal integration that saves board space and BOM cost in sensor-front-end or control-loop designs where you'd otherwise need a separate ADC and op-amp stage. Supply range from 2.4 V to 5.25 V.

Active, ROHS3, and available

No last-time-buy notice, no end-of-life pressure — it's a current-production line that Infineon continues to support.

Frequently asked questions

What is the closest functional second-source for CY8C24423A-24LTXIT?

Within the same PSoC 1 family, the CY8C29566-24AXIT offers a 40-I/O variant with 12x14b ADC and 4x9b DAC but a different package (TQFP). For a pin-compatible drop-in with more I/O, the CY8C29466-24PVXI shares the 24-I/O count and same 24 MHz M8C core but comes in a DIP package. Neither is a direct second-source; verify footprint and firmware porting before substituting.
