Technical Details & Description

Active production, 28-SSOP, industrial temp — what this PSoC 1 brings

The Cypress CY8C27443-24PVXIT is an 8-bit PSoC 1 microcontroller from the CY8C27xxx family, built around the M8C core running at 24 MHz.

Where it fits — industrial control, sensor interface, mixed-signal front end

The 14-bit ADC resolution is enough for many pressure, temperature, and current-sense applications without an external converter. The 9-bit DAC can generate analog setpoints or bias voltages. The POR, PWM, and WDT peripherals cover the usual watchdog and timing needs for a standalone controller.

24 MHz M8C core and memory — sizing the firmware fit

The M8C core runs at 24 MHz. The 16 KB Flash and 256 x 8 RAM are the memory limits.

Package and supply — board-fit notes

The 28-SSOP package (0.209" body width, 5.30 mm) is a common footprint that reflows well with standard profiles. Surface-mount only — no through-hole variant.

ROHS3 compliant per the listing.

Frequently asked questions

What is the replacement or equivalent for CY8C27443-24PVXIT?

Within the same PSoC 1 family, the CY8C29466-24PVXI is a close functional match — same 28-SSOP package, same 24 I/O count, but with a 12-channel 14-bit ADC instead of 4-channel. The CY8C29566-24AXIT steps up to 40 I/O in a 48-pin QFP. Neither is a drop-in replacement; review the peripheral differences and pinout before substituting. There is no official second-source from another manufacturer for this proprietary PSoC architecture.

Is CY8C27443-24PVXIT compatible with PSoC Designer?

Yes, as a PSoC 1 device (CY8C27xxx series), it is supported by Cypress's PSoC Designer IDE, which provides the graphical configuration tools for the analog and digital blocks. The device-specific configuration files are included in the toolchain.

Is CY8C27443-24PVXIT RoHS compliant?

Yes, it is listed as ROHS3 compliant.
