Overview
The CY8C3244LTI-123T is an Infineon PSoC 3 microcontroller featuring a single-cycle 8051 CPU operating up to 50 MHz. It integrates 64 KB of Flash, 8 KB of SRAM, and 2 KB of EEPROM within a 68-pin QFN package. The device supports a supply voltage range of 1.71 V to 5.5 V and includes a 12-bit Delta-Sigma ADC, USB 2.0 Full-Speed interface, and CapSense technology.
Feature Summary
- Integrates a high-performance single-cycle 8051 CPU with DMA controller for efficient data handling
- Features programmable analog and digital subsystems including a 12-bit Delta-Sigma ADC and CapSense touch sensing
- Supports multiple communication protocols via Universal Digital Blocks (UDB) such as I2C, SPI, UART, and USB 2.0
Applications
- Consumer electronics requiring low power consumption and flexible I/O
- Industrial control systems utilizing programmable logic and analog peripherals
- Medical devices needing precise analog signal processing and safety features
Procurement Notes
Verify the specific ordering suffix LTI-123T against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with PSoC Creator development tools. Check for RoHS compliance status in the latest datasheet revision before procurement.
Selection Notes
Select this component when a combination of 8051 architecture, significant on-chip memory, and mixed-signal programmability is required. Consider the 68-pin QFN package constraints and verify that the 50 MHz clock speed meets system timing requirements alongside the available GPIO count.
Part Context
This part belongs to the Infineon PSoC 3 CY8C32 series, designed for highly integrated embedded applications. It combines a standard 8051 core with configurable analog and digital blocks, allowing designers to replace multiple discrete components with a single chip solution.
Replacement Considerations
Consult the official Infineon PSoC 3 product selector for direct pin-to-pin or functional equivalents within the same family. Verify memory sizes and package dimensions when considering alternative models.
