CY8C3244PVI-133T

Overview

The Infineon CY8C3244PVI-133T is an 8-bit microcontroller from the PSoC 3 family, featuring a single-cycle 8051 CPU with a maximum clock frequency of 50 MHz. It integrates 16 kB of Flash program memory and 2 kB of SRAM within a 48-pin SSOP package. The device supports a supply voltage range of 1.71 V to 5.5 V and includes a 12-bit Delta-Sigma ADC. Key digital peripherals include I2C, SPI, UART, and USB interfaces, alongside four TCPWM modules.

Feature Summary

• Integrates a high-performance single-cycle 8051 CPU with DMA controller for efficient data handling
• Features programmable analog and digital subsystems allowing flexible peripheral configuration
• Supports low-power operation with multiple sleep and deep sleep modes
• Includes certified Full-Speed USB 2.0 interface for communication

Applications

• Embedded control systems requiring mixed-signal processing
• USB-enabled consumer electronics devices
• Industrial monitoring applications with sensor inputs
• Battery-powered portable equipment

Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the SSOP-48 package variant matches your board layout requirements. Ensure compatibility with the PSoC Creator development environment for firmware implementation. Check RoHS compliance status for environmental regulations.

Selection Notes

Select this model if a 48-pin form factor with integrated USB connectivity is required. Consider the 16 kB Flash capacity against application code size needs. Evaluate the 29 available I/O pins for system interface requirements. Compare power consumption profiles in active versus sleep modes for battery life optimization.

Part Context

This component belongs to the Infineon PSoC 3 CY8C32 series, designed for highly configurable embedded applications. It combines an 8051 core with programmable analog and digital blocks on a single chip. The series targets cost-sensitive designs needing flexibility in hardware configuration without external discrete components.

Replacement Considerations

Check official Infineon documentation for direct pin-to-pin compatible replacements within the CY8C32 series. Verify memory sizes and package dimensions before substituting. Cross-reference feature sets to ensure peripheral availability matches design requirements.
