CY8C4247AZI-L433

Overview

The CY8C4247AZI-L433 is a PSoC 4200L microcontroller based on the Arm Cortex-M0 core, operating at up to 48 MHz. It features 128 kB of Flash memory and 16 kB of SRAM within a 64-pin TQFP package. The device includes one 12-bit SAR ADC with 32 analog input channels, two low-power comparators, and four opamps. Connectivity is provided by three Serial Communication Blocks (SCBs) supporting I2C, SPI, and UART, alongside a USB Full-Speed client controller. It supports CAPSENSE technology and segment LCD drive, functioning within a voltage range of 1.71 V to 5.5 V.

Feature Summary

• Integrates programmable analog blocks including opamps and comparators that operate in Deep Sleep mode for low-power sensing applications.
• Provides flexible digital logic through Universal Digital Blocks (UDBs) allowing custom peripheral creation and reconfigurable serial communication interfaces.
• Supports capacitive sensing via dedicated Sigma-Delta blocks with automatic hardware tuning capabilities.

Applications

• Industrial control systems requiring mixed-signal processing
• Battery-powered devices utilizing low-power sleep modes
• Human-machine interfaces incorporating capacitive touch or LCD displays

Procurement Notes

Verify the specific suffix L433 against the official Infineon datasheet to confirm pinout compatibility and package type. Ensure design requirements align with the 64-pin TQFP configuration and the specified voltage range. Confirm that the available GPIO count meets the interface needs before finalizing procurement.

Selection Notes

Select this component when a balance of programmable analog flexibility and standard MCU functionality is required. It is suitable for designs needing multiple serial interfaces and analog signal conditioning without external components. Consider the 48 MHz performance limit and memory size relative to application complexity.

Part Context

This part belongs to the PSoC 4200L family, which emphasizes low power consumption and mixed-signal programmability. Unlike fixed-function MCUs, it allows hardware reconfiguration via PSoC Creator. The L-series designation typically indicates specific package and temperature grade variations within the broader PSoC 4 portfolio.

Replacement Considerations

Check for CY8C4247AZI-L433T if tape-and-reel packaging is preferred over trays. Verify CY8C4247AZI-M485 only if the pinout and peripheral configuration match exactly, as suffix changes may alter package or speed grades.
