CY8C4246AZI-L433T

Overview

The CY8C4246AZI-L433T is a PSoC 4200L microcontroller from Infineon Technologies, based on the Arm Cortex-M0 core. It features 64 kB of Flash memory and 8 kB of SRAM. The device operates within a voltage range of 1.71 V to 5.5 V and supports a maximum clock frequency of 48 MHz. It includes a 12-bit SAR ADC, four opamps, two low-power comparators, and eight TCPWM blocks. The component is housed in a TQFP-48 package with 38 I/O pins.

Feature Summary

• Integrates programmable analog and digital subsystems for flexible system design
• Supports capacitive sensing with automatic hardware tuning capabilities
• Includes USB Full-Speed device interface with Battery Charger Detect
• Features multiple serial communication blocks supporting I2C, SPI, and UART

Applications

• Industrial control systems requiring programmable logic
• Battery-powered devices utilizing low-power modes
• Consumer electronics with capacitive touch interfaces
• Automotive networking applications using CAN blocks

Procurement Notes

Verify the specific ordering suffix L433T corresponds to the TQFP-48 package and reel packaging configuration. Confirm that the device meets RoHS compliance requirements for your region. Ensure compatibility with the PSoC Creator IDE or Arm-based development tools during the sourcing phase.

Selection Notes

Select this model when a balance of moderate Flash capacity and low power consumption is required. The TQFP-48 package offers a suitable pin count for general-purpose applications. Consider the 48 MHz performance limit and 12-bit ADC resolution against higher-end PSoC 4 variants if greater precision or speed is needed.

Part Context

This part belongs to the PSoC 4200L family, which is optimized for low-power applications. It shares architectural similarities with the broader PSoC 4 platform but focuses on energy efficiency. The device is compatible with other members of the PSoC 4 family for upward migration or design flexibility.

Replacement Considerations

Check for CY8C4246AZI-L433 without the 'T' suffix if tray packaging is preferred instead of reel. Verify CY8C4246AZI-S433 only if a different package type like WLCSP is acceptable, noting potential pinout differences.
