Product details
Overview
CY8C4246AZI-M475 from Infineon is a PSoC™ 4200M programmable system-on-chip integrating an Arm® Cortex®-M0 CPU (48 MHz), 128 kB flash, 16 kB SRAM, and reconfigurable analog/digital blocks. It delivers capacitive sensing (CSD), LCD segment drive, dual CAN interfaces, and TCPWM for motor control in industrial HMI and embedded sensor nodes.
For engineers reviewing the CY8C4246AZI-M475 datasheet, CY8C4246AZI-M475 pinout, CY8C4246AZI-M475 application, or CY8C4246AZI-M475 equivalent, key selection criteria include Deep Sleep current (20 nA), SAR ADC performance (12-bit, 1 Msps), opamp operation in low-power modes, and UDB-based digital logic reconfiguration capability.
Technical Context
The device implements a tightly coupled MCU subsystem with DMA engine and Read Accelerator for deterministic flash access. Its analog subsystem includes four rail-to-rail opamps with comparator/ADC buffer modes and two low-power comparators-all functional in Deep Sleep mode at sub-μA currents.
Digital flexibility stems from four Universal Digital Blocks (UDBs), each with 8 macrocells and 8-bit datapath, enabling custom state machines or peripheral logic. Two independent CAN 2.0B controllers support industrial networking, while eight TCPWM blocks provide center-aligned PWM with comparator-triggered kill signals for motor safety.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-M485 | Same core, but 64-pin QFN package with 48 GPIOs (vs. 55) and no CAN blocks - lacks dual-CAN capability. | Suitable for cost-sensitive HMI-only designs without fieldbus requirements. | Select when CAN is unnecessary and smaller footprint is prioritized over I/O count. |
| STM32L476RG | Arm Cortex-M4F @ 80 MHz, 1 MB flash, no programmable analog/digital logic - relies on fixed peripherals and external components. | Better for compute-intensive tasks but requires external opamps, touch controllers, and CAN transceivers. | Choose when floating-point math or higher clock speed outweighs analog/digital reconfigurability and integration benefits. |
Compared with CY8C4246AZI-M475, CY8C4247LQI-M485 trades CAN and I/O for compactness, while STM32L476RG offers higher CPU performance at the cost of increased BOM complexity and loss of hardware-level analog/digital customization.

FAQ
Does CY8C4246AZI-M475 support USB connectivity?
No. The device does not include a USB PHY or controller. It supports I²C, SPI, UART, and CAN interfaces only. For USB host or device functionality, an external USB bridge IC (e.g., CP2102N or FT232H) must be used with SCB-based UART or SPI communication.
What debugging interfaces are supported?
CY8C4246AZI-M475 supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins. It is fully compatible with Infineon's KitProg3 and third-party ARM-compliant debug probes (e.g., Segger J-Link). No JTAG support is provided.
Can the opamps operate independently of the CPU clock?
Yes. All four opamps remain fully functional in Deep Sleep and Hibernate modes with independent bias control. Their operation is sustained by the internal low-speed oscillator (ILO) or external clock sources, enabling continuous analog signal conditioning without CPU wake-up.
Is the CSD engine compliant with IEC 61000-4-6 conducted immunity standards?
Yes. The CSD implementation meets IEC 61000-4-6 Level 3 (10 Vrms) when implemented per Infineon's layout and shielding guidelines in AN92239 and the PSoC™ 4200M hardware design checklist. System-level compliance requires proper PCB grounding and shielded sensor traces.
