Product details
Overview
CY8C4246AZI-L423 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-L423 datasheet, CY8C4246AZI-L423 pinout, CY8C4246AZI-L423 application, or CY8C4246AZI-L423 equivalent, key selection criteria include Deep Sleep current (20 nA), 94 GPIOs with CAPSENSE™ support, dual CAN 2.0B compliance, CSD SNR >5:1, and USB Battery Charger Detect capability.
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 operable in Deep Sleep mode and two low-power comparators, all configurable via hardware routing to any GPIO.
Digital flexibility is delivered through 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 SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LTI-L485 | Same PSoC™ 4200L family; adds 16 kB additional SRAM and 128 kB extra flash. | Better suited for firmware-over-the-air (FOTA) implementations requiring dual-bank flash and larger RAM buffers. | Select when firmware update resilience and real-time data buffering outweigh cost sensitivity. |
| STM32G474RE | Arm® Cortex®-M4F core, no integrated capacitive sensing or UDBs; requires external touch controller. | Lacks native CSD and programmable logic - demands additional components for touch HMI or custom digital logic. | Prefer when floating-point math, DSP acceleration, or higher clock stability are primary requirements over analog/digital configurability. |
Compared with CY8C4246AZI-L423, CY8C4247LTI-L485 offers expanded memory for secure firmware updates, while STM32G474RE trades PSoC's analog/digital reconfigurability for higher CPU performance and FPU - making the former optimal for mixed-signal customization and the latter for compute-intensive control loops.

FAQ
Does CY8C4246AZI-L423 support USB device enumeration without external PHY?
Yes. The part integrates a full-speed USB 2.0 transceiver with on-die termination resistors and Battery Charger Detect (BCD) logic. It enumerates as a USB device using only the internal PHY and standard USB_DP/USB_DM pins - no external components required for basic HID or CDC-class devices.
What is the maximum operating temperature range for this device?
CY8C4246AZI-L423 is rated for industrial temperature operation from –40 °C to +85 °C. This range is validated per JEDEC JESD22-A104 and applies to all specified electrical parameters, including CAN bus timing, ADC accuracy, and Deep Sleep current.
Can the opamps be used in rail-to-rail input/output configuration?
Yes. All four CTBm opamps support rail-to-rail input and output operation when powered from VDDA = VDDD. Input common-mode range extends from VSSA to VDDA, and output swing reaches within 20 mV of either rail under 1 mA load - verified in the Electrical Specifications section of the datasheet (Rev. *L, Table 5.3.1).
Is there hardware support for AES encryption in this variant?
No. CY8C4246AZI-L423 does not include a dedicated hardware AES accelerator. Cryptographic operations must be implemented in firmware using the Cortex®-M0 core. For hardware-accelerated security, consider the PSoC™ 4100S or PSoC™ 6 families, which integrate TRNG and cryptographic engines.
