CY8C3244AXI-153T

Overview

The CY8C3244AXI-153T 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 within a 100-pin TQFP package. The device supports a maximum operating frequency of 50 MHz and operates across a supply voltage range of 1.71 V to 5.5 V. Key peripherals include a 12-bit Delta-Sigma ADC, four TCPWM modules, hardware I2C, and Full-Speed USB 2.0 interfaces.

Feature Summary

• Integrates a high-performance single-cycle 8051 CPU with DMA controller for efficient data handling
• Features highly configurable analog and digital subsystems via Universal Digital Blocks (UDB)
• Supports CapSense touch sensing technology for intuitive user interface applications
• Includes integrated boost converter allowing operation from low input voltages

Applications

• Consumer electronics requiring programmable mixed-signal control
• Industrial systems utilizing sensor interfacing and communication protocols
• Medical devices needing precise analog signal acquisition and processing
• Embedded controllers implementing USB connectivity and touch sensing

Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging configuration when sourcing components. Confirm that the 100-TQFP package variant matches your board layout requirements. Ensure compatibility with the PSoC Creator development environment for firmware implementation. Check for moisture sensitivity level compliance during storage and assembly processes.

Selection Notes

Select this component for designs requiring flexible analog-digital integration on a single chip. The 8051 architecture suits developers familiar with standard instruction sets while needing peripheral configurability. Consider the 100-pin form factor if extensive GPIO routing or multiple communication interfaces are necessary. Evaluate power consumption profiles against the available sleep and deep sleep modes for battery-operated constraints.

Part Context

This part belongs to the PSoC 3 CY8C32 series, which combines a microcontroller with programmable analog and digital blocks. The series targets applications demanding system-level integration, reducing component count and board space. It utilizes the PSoC Creator IDE for hardware and firmware co-design, enabling rapid prototyping through drag-and-drop component placement.

Replacement Considerations

Consult official Infineon documentation for verified cross-references. Substitution requires matching the 8051 core, memory sizes, and pinout compatibility. Verify that alternative packages maintain identical electrical specifications and thermal characteristics.
