Product details
Overview
CY8C4246AZI-L433T from Infineon is a PSoC™ 4200L programmable system-on-chip featuring a 48 MHz Arm® Cortex®-M0 CPU, 256 kB flash, 32 kB SRAM, four opamps with comparator mode, and dual CAN controllers. It integrates reconfigurable analog/digital blocks, capacitive sensing (CSD), and USB Full-Speed for embedded control in industrial HMI and motor drive interfaces.
For engineers reviewing the CY8C4246AZI-L433T datasheet, CY8C4246AZI-L433T pinout, CY8C4246AZI-L433T application, or CY8C4246AZI-L433T equivalent, key selection criteria include Deep Sleep current (20 nA), 94 GPIOs with CAPSENSE™ support, 8 TCPWM blocks, dual CAN 2.0B compliance, and VFBGA-124 package compatibility.
Technical Context
The device implements a tightly coupled MCU subsystem with DMA-driven peripheral arbitration and configurable clock tree (IMO/ILO/PLL). Its analog subsystem includes four CTBm opamp blocks supporting simultaneous ADC buffering, comparator latching, and low-power Deep Sleep operation at 20 nA.
Digital resources comprise eight UDBs for custom logic synthesis, four SCBs supporting runtime-reconfigurable I²C/SPI/UART, two fixed-function CAN controllers compliant with ISO 11898-1, and eight TCPWM blocks with kill-input triggering for motor control safety.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-BL483 | Same PSoC™ 4200L architecture but 68-pin QFN package; lacks VFBGA thermal pad | Better suited for prototyping and manual soldering; lower I/O count (62 vs. 94) | Select when thermal management is less critical and board assembly favors QFN reflow |
| STM32G474RET6 | Arm Cortex-M4F core, no integrated CAPSENSE™ or UDBs; requires external touch controller | Higher floating-point throughput for motor FOC, but adds BOM cost and layout complexity for touch | Select when advanced math-intensive algorithms dominate over capacitive UI requirements |
Compared with CY8C4246AZI-L433T, CY8C4247LQI-BL483 trades package thermal performance for assembly flexibility, while STM32G474RET6 offers higher CPU performance at the expense of integrated analog/digital reconfigurability and touch capability.

FAQ
What debug interface does CY8C4246AZI-L433T support?
CY8C4246AZI-L433T uses ARM Serial Wire Debug (SWD) with SWDCK and SWDIO pins. It supports full programming, real-time debugging, and trace via MiniProg4 or compatible CMSIS-DAP adapters. No JTAG header is required, reducing PCB footprint and enabling in-system firmware updates without physical access to debug headers.
Does this device support USB and CAN simultaneously?
Yes. CY8C4246AZI-L433T integrates one USB Full-Speed (12 Mbps) controller and two independent CAN 2.0B controllers. All three interfaces operate concurrently with dedicated DMA channels and non-overlapping memory-mapped registers, enabling simultaneous USB diagnostics and dual-CAN fieldbus communication in automotive gateways.
What is the maximum operating temperature for this VFBGA package?
The CY8C4246AZI-L433T in 124-ball VFBGA is rated for industrial temperature range: –40 °C to +85 °C ambient. The exposed thermal pad enhances heat dissipation, allowing sustained operation at full 48 MHz CPU speed and 94 GPIOs active under worst-case airflow conditions.
How many capacitive sensing buttons can be implemented?
Up to 94 GPIO pins support CAPSENSE™, with hardware-accelerated scanning across both CSD blocks. Each CSD block handles up to 32 electrodes, enabling 64-button touch panels or 32-channel proximity sensing. SmartSense™ auto-tuning eliminates manual calibration, delivering production-ready performance across voltage, temperature, and humidity variations.
