Product details
Overview
CY8C4246AZI-L423T 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 automotive body electronics.
For engineers reviewing the CY8C4246AZI-L423T datasheet, CY8C4246AZI-L423T pinout, CY8C4246AZI-L423T application, or CY8C4246AZI-L423T equivalent, key selection criteria include Deep Sleep current (20 nA), 94 GPIOs with CAPSENSE™ support, 8 TCPWM blocks, dual CAN 2.0B interfaces, and VFBGA-124 package compatibility.
Technical Context
The device implements an Arm® Cortex®-M0 core with single-cycle multiply and a dedicated DMA engine supporting 32 channels. Its analog subsystem includes four CTBm opamps-each configurable as amplifier, comparator, or ADC buffer-with operation down to 20 nA in Deep Sleep mode.
Digital flexibility derives from eight Universal Digital Blocks (UDBs), each with 8 macrocells and an 8-bit datapath, plus four reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART and two fixed-function CAN 2.0B controllers compliant with ISO 11898-1.

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 family; 256 kB flash, but QFN-68 package and no USB interface | Lacks USB PHY and battery charger detect; suited for space-constrained CAN-only nodes | Select when USB is unnecessary and board area is critical; pinout incompatible with VFBGA-124 |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz, 512 kB flash, no integrated CAPSENSE™ or UDBs | Requires external touch controller and FPGA/CPLD for custom logic; higher compute throughput | Choose for floating-point math-intensive tasks where analog/digital reconfigurability is secondary |
Compared with CY8C4246AZI-L423T, CY8C4247LQI-BL483 trades USB and package size for footprint reduction, while STM32G474RET6 offers higher CPU performance but lacks hardware-accelerated capacitive sensing and programmable logic blocks-requiring additional components for equivalent system functionality.

FAQ
What debug interface does CY8C4246AZI-L423T support?
CY8C4246AZI-L423T uses a two-pin Serial Wire Debug (SWD) interface via SWDCK and SWDIO pins. It is fully compatible with Infineon's MiniProg4 programmer/debugger and standard Arm® CoreSight-compliant tools such as Segger J-Link and ST-Link v2. No JTAG header is required.
Does this device support hardware-based capacitive sensing without external components?
Yes. The device integrates two dedicated Capacitive Sigma-Delta (CSD) sensing blocks with SmartSense™ auto-tuning. These blocks perform raw capacitance measurement, baseline tracking, and noise rejection entirely in hardware-requiring only PCB traces as sensors and no external RC networks or dedicated touch ICs.
Can both CAN controllers operate simultaneously at different bit rates?
Yes. The two CAN 2.0B controllers are electrically and logically independent. Each has its own clock domain, message RAM, and filter configuration, allowing concurrent operation at distinct bit rates (e.g., 500 kbps on CAN0 and 125 kbps on CAN1) without resource contention or software scheduling.
Is the 256 kB flash memory subject to wear-out during firmware updates?
The flash supports ≥100,000 erase/write cycles per sector as specified in the datasheet. Wear leveling must be implemented in firmware or bootloader logic. Infineon provides PSoC™ Creator APIs and example projects demonstrating safe over-the-air update routines using dual-bank flash partitioning.
