CY8C27443-24PVXI

Overview

The CY8C27443-24PVXI is an 8-bit microcontroller from the Infineon 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 at a maximum clock frequency of 24 MHz within a supply voltage range of 3 V to 5.25 V. It includes a 14-bit ADC with 12 channels, four 9-bit DACs, and two timers/counters. Connectivity is provided via GPIO, I2C, SPI, and UART interfaces. The component is housed in a 28-pin SSOP package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates configurable analog and digital peripherals within a mixed-signal system-on-chip architecture.
• Provides programmable interconnects allowing flexible routing of internal signals to external pins.
• Supports CapSense touch sensing capabilities for user interface applications.

Applications

• Consumer electronics requiring low power consumption and small form factors
• Industrial control systems needing mixed-signal processing
• Automotive instrumentation and monitoring devices

Procurement Notes

Verify the specific suffix 'X' indicates the industrial temperature grade and RoHS compliance status against the manufacturer's current datasheet. Confirm the package type matches the required PCB footprint, as variations exist within the series. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this model when 16 kB of Flash and 256 bytes of RAM are sufficient for the application logic. The 24 MHz speed and 14-bit ADC resolution suit moderate-performance mixed-signal tasks. Consider alternative pin counts if more than 16 I/O lines are required, or different memory sizes if larger code storage is needed.

Part Context

This component belongs to the PSoC 1 CY8C27xxx series, designed for cost-sensitive embedded applications. It combines an 8-bit CPU with programmable analog blocks, distinguishing it from standard microcontrollers by offering hardware-configurable signal chains without external components.

Replacement Considerations

Check for CY8C27443 variants with different suffixes indicating package changes or temperature ranges. Verify compatibility with CY8C27x43 family members sharing identical memory maps and peripheral configurations.
