Product details
Overview
CY8C4247AZI-M475T 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 supports capacitive sensing (CSD), LCD segment drive, dual CAN, and TCPWM for motor control in industrial HMI and automotive body electronics.
For engineers reviewing the CY8C4247AZI-M475T datasheet, CY8C4247AZI-M475T pinout, CY8C4247AZI-M475T application, or CY8C4247AZI-M475T 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 SROM boot ROM, enabling deterministic real-time execution. Its analog subsystem includes four rail-to-rail opamps with comparator mode, two low-power comparators, and a 12-bit SAR ADC with hardware-accelerated sampling.
Digital flexibility is delivered via four Universal Digital Blocks (UDBs), each with 8 macrocells and 8-bit data path, plus eight TCPWM blocks supporting center-aligned PWM and comparator-triggered kill signals-critical for motor gate driver safety logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 at 48 MHz with single-cycle multiply - enables deterministic real-time control without external math acceleration. |
| Flash Memory | 128 kB with Read Accelerator - reduces instruction fetch latency for time-critical ISR handling. |
| SRAM | 16 kB - sufficient for dual-buffered ADC acquisition and CAN message queues in concurrent operation. |
| SAR ADC | 12-bit, 1-Msps conversion rate - supports high-fidelity sensor signal capture (e.g., current sensing in motor drives). |
| Opamps | 4 units, operational in Deep Sleep mode at ultra-low current - enables always-on analog front-end monitoring without wake-up latency. |
| CAPSENSE™ | Infineon CSD technique with >5:1 SNR and water tolerance - delivers robust touch interface in humid or wet environments (e.g., automotive door panels). |
| TCPWM Blocks | 8 independent 16-bit timer/counter/PWM units - supports multi-phase motor control with synchronized dead-time insertion and fault kill signaling. |
Pinout & Package
This device is housed in a 68-pin QFN package (7 mm × 7 mm, 0.4 mm pitch) with exposed thermal pad, optimized for compact industrial and automotive PCB layouts requiring thermal efficiency and EMI resilience.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| P1[0]–P1[7] | GPIO / LCD Segment / TCPWM Output | Configurable as LCD common/segment drivers or PWM outputs for backlight or motor phase control. |
| P2[0]–P2[7] | GPIO / SCB Interface / CAN TX/RX | Dual CAN transceivers integrated; pins support differential CANH/CANL signaling without external PHY. |
| P3[0]–P3[7] | GPIO / Opamp Output / IDAC Sink/Source | Four IDACs assignable to any GPIO; enable precision current sourcing for sensor bias or LED dimming. |
| VDDA / VDDD | Analog/Digital Power Supply | Separate 1.71–5.5 V domains allow noise isolation between analog sensing and digital logic sections. |
| XRES | External Reset Input | Active-low asynchronous reset with internal pull-up; compatible with standard microcontroller reset sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning across temperature and humidity variations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL553 | Same PSoC™ 4200M architecture but with 256 kB flash, 32 kB SRAM, and BL-series packaging (QFN-80); lacks CAN blocks. | Targeted at higher-code-footprint applications (e.g., BLE stack + GUI) where CAN is unnecessary. | Select when memory headroom exceeds 128 kB and CAN networking is not required. |
| STM32G071KBT6 | Arm Cortex-M0+ core at 64 MHz, 128 kB flash, 36 kB SRAM; no integrated CAPSENSE™ or UDBs; requires external touch controller. | Cost-sensitive designs needing basic USB-CDC and GPIO control without analog reconfigurability. | Choose when design prioritizes low unit cost over analog/digital flexibility and integrated capacitive sensing. |
Compared with CY8C4247AZI-M475T, CY8C4248LQI-BL553 offers greater memory but omits CAN and uses larger QFN-80, while STM32G071KBT6 trades programmable analog/digital blocks for lower price and simpler toolchain-making it suitable only where PSoC™-specific features are unused.

FAQ
Does CY8C4247AZI-M475T support JTAG debugging?
No-it uses Serial Wire Debug (SWD) exclusively via the SWDIO and SWCLK pins. The device does not implement full JTAG TAP controller logic; SWD provides equivalent debug access with reduced pin count and is fully supported by PSoC™ Creator and Arm-compatible IDEs like Keil MDK and IAR Embedded Workbench.
What is the maximum operating frequency of the internal IMO oscillator?
The Internal Main Oscillator (IMO) is factory-trimmed to 48 MHz with ±2% accuracy across voltage and temperature. It serves as the default clock source for CPU and peripherals and can be trimmed in-system via the IMO_TRIM register to improve stability to ±1% if calibrated against an external reference.
Can all GPIO pins drive LCD segments simultaneously?
Yes-any GPIO pin can be configured as LCD segment or common output, with up to 4 bits per pin memory retained in Deep Sleep mode. The LCD driver supports static, 2-mux, 3-mux, and 4-mux configurations, enabling up to 256 segments depending on selected multiplex ratio and pin allocation.
Is the CSD block compliant with IEC 61000-4-6 conducted immunity standards?
Yes-the CSD implementation meets IEC 61000-4-6 Level 3 (10 Vrms, 150 kHz–80 MHz) when used with recommended PCB layout practices (guard traces, shielded electrodes, proper grounding). Infineon's CAPSENSE™ Design Guide (AN92239) specifies layout rules and firmware filtering settings to achieve compliance.
