CY8C3244PVA-133

Overview

The CY8C3244PVA-133 is an 8-bit microcontroller from the Infineon PSoC 3 family, featuring a single-cycle 8051 CPU core. It integrates 16 kB of Flash program memory and 2 kB of SRAM data memory. The device supports a maximum clock frequency of 50 MHz and operates within a supply voltage range of 1.71 V to 5.5 V. It includes a 12-bit ADC, four 16-bit timers/PWMs, and multiple communication interfaces including USB, I2C, SPI, and UART. The component is housed in an SSOP-48 package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-performance single-cycle 8051 processor with extensive analog and digital programmability subsystems.
• Supports CapSense touch sensing capabilities for intuitive human-machine interface applications.
• Provides full-speed USB 2.0 connectivity alongside standard serial communication protocols.

Applications

• Consumer electronics requiring low power consumption and integrated control
• Industrial control systems needing reliable 8-bit processing
• Medical devices utilizing precise analog signal acquisition

Procurement Notes

Verify the specific suffix 'PVA' against official Infineon documentation to confirm pinout and package variations compared to similar models like PVI. Ensure compatibility with PSoC Creator development tools. Check for moisture sensitivity levels and reflow soldering profile requirements during assembly planning.

Selection Notes

Select this model when a balance of 8051 compatibility and PSoC programmability is required. Consider the 16 kB Flash limit for code size and verify that the SSOP-48 package fits the PCB layout constraints. Evaluate if the 50 MHz speed meets real-time processing needs for the target application.

Part Context

This component belongs to the PSoC 3 series, designed for highly integrated solutions combining analog and digital blocks. It targets applications demanding flexibility and low power, serving as a bridge between traditional 8-bit MCUs and more complex 32-bit architectures.

Replacement Considerations

Check for direct substitutes within the CY8C3244 family or upgraded CY8C32x6A series. Verify pin-to-pin compatibility and software register mapping before swapping components in existing designs.
