CY8C27443-24PVXI

Overview

The CY8C27443-24PVXI is an 8-bit microcontroller within the PSoC 1 family, utilizing the M8C core. It features 16 kB of Flash program memory and 256 bytes of SRAM data RAM. The device operates with a maximum clock frequency of 24 MHz and supports a supply voltage range of 3 V to 5.25 V. It includes a 14-bit ADC with 12 channels, two timers/counters, and interfaces such as I2C, SPI, and UART. The component is housed in a 28-pin SSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates configurable analog and digital peripherals for system-level flexibility
• Combines an 8-bit microcontroller with embedded Flash and SRAM memory
• Supports mixed-signal applications through high-resolution ADC capabilities

Applications

• Consumer electronics devices
• Industrial equipment control systems
• Communication interface modules

Procurement Notes

Verify the manufacturer designation, as Infineon Technologies acquired Cypress Semiconductor. Confirm the specific suffix PVXI corresponds to the 28-SSOP package and commercial temperature grade. Ensure compatibility with existing design files when sourcing from current Infineon distribution channels rather than legacy Cypress stock.

Selection Notes

Select this component for designs requiring mixed-signal processing with a compact 28-pin footprint. It is suitable for applications needing multiple analog inputs and standard serial communication interfaces. Consider the 16 kB memory limit for complex firmware requirements and verify power supply constraints against the 3 V to 5.25 V operating range.

Part Context

This part belongs to the PSoC 1 CY8C27xxx series, which provides a complete system-on-chip solution. The series is designed to reduce board space and component count by integrating programmable analog blocks with digital logic and an 8-bit CPU. It targets markets requiring flexible, low-power mixed-signal control.

Replacement Considerations

Check for CY8C27443 variants with different speed grades or packages. Verify if CY8C27643 offers sufficient pinout compatibility despite having more I/O lines. Ensure any substitute maintains the same SSOP-28 form factor and memory configuration.
