Product details
Overview
CY8C4247AZI-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 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-M475 datasheet, CY8C4247AZI-M475 pinout, CY8C4247AZI-M475 application, or CY8C4247AZI-M475 equivalent, key selection criteria include Deep Sleep current (20 nA), SAR ADC performance (12-bit, 1-Msps), opamp count (4), UDB count (4), and CAN block availability (2) - all confirmed in the 001-93963 Rev. *M datasheet.
Technical Context
The device implements a tightly coupled architecture where the Cortex-M0 core interfaces with programmable analog blocks (opamps, comparators, IDACs, 12-bit SAR ADC) and digital logic (UDBs, TCPWM, SCBs). All analog peripherals operate in Deep Sleep mode, enabling ultra-low-power wake-up sensing.
Dual CAN controllers support ISO 11898-1 compliance with configurable bit timing and error handling; four SCBs provide runtime-reconfigurable I²C/SPI/UART; eight TCPWM blocks support center-aligned PWM with comparator-triggered kill signals for motor safety.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz with single-cycle multiply - enables real-time control loop execution in <21 ns per instruction. |
| Flash Memory | 128 kB with Read Accelerator - supports fast code execution and firmware updates without performance penalty. |
| SRAM | 16 kB - sufficient for RTOS stacks, sensor buffers, and CAN message queues in embedded applications. |
| SAR ADC | 12-bit, 1-Msps - delivers 60-dB SNR for precision analog signal acquisition in motor current sensing or battery monitoring. |
| Opamps | 4 units, Deep Sleep capable - enable always-on analog front-end conditioning with sub-µA quiescent current. |
| CAN Interfaces | 2 independent blocks - allow redundant communication or multi-bus topology (e.g., powertrain + body networks). |
| GPIO Count | Up to 55 programmable pins - supports mixed-signal routing for CAPSENSE™, LCD, analog, and digital functions on shared pins. |
Pinout & Package
This device is offered in a 68-pin QFN package (7 mm × 7 mm, 0.4 mm pitch) with exposed thermal pad. Pin assignments are validated per Infineon's official pinout diagram (Section 4, Datasheet 001-93963 Rev. *M).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O Power Supply | Independent 1.71–5.5 V domains per port group - enable mixed-voltage interface (e.g., 3.3 V MCU core + 1.8 V sensor I/O). |
| P0[0]–P0[7] | Programmable GPIO | Support CAPSENSE™, LCD segment/common, analog input, or digital logic - routed via internal interconnect matrix. |
| CAN0_TX / CAN0_RX | CAN Physical Interface | Differential signaling pair compliant with ISO 11898-2 - requires external transceiver for bus termination and level shifting. |
| SWDCLK / SWDIO | Debug Interface | 2-pin Serial Wire Debug - enables non-intrusive programming and real-time trace without dedicated JTAG pins. |
| XRES | External Reset Input | Active-low asynchronous reset with internal pull-up - ensures deterministic startup after power-on or brown-out events. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CAPSENSE™ calibration - eliminates manual threshold tuning across temperature/humidity variations. |
| Deep Sleep Opamp Operation | Sub-1 µA quiescent current per opamp - enables continuous analog signal monitoring during 20-nA Stop Mode. |
| Universal Digital Blocks (UDBs) | 4 blocks × 8 macrocells - implement custom state machines or glue logic without consuming CPU cycles. |
| LCD Direct Drive | Segment/common drive on all GPIOs - supports up to 240-segment displays with 4-bit memory per pin in Deep Sleep. |
| Comparator-Triggered Kill Signal | Hardware-level TCPWM shutdown in <100 ns - meets functional safety requirements for motor overcurrent protection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL553 | Same PSoC™ 4200M family but with Bluetooth LE radio and 256 kB flash - no CAN blocks. | Targets wireless sensor nodes; lacks dual CAN required for automotive body networks. | Select only when BLE connectivity outweighs CAN requirement and flash headroom is critical. |
| STM32F303VCT6 | Arm Cortex-M4F @ 72 MHz, 256 kB flash, 48 kB RAM, but fixed-function peripherals - no programmable analog/digital blocks. | Requires external opamps, DACs, and logic for CAPSENSE™ or custom timing - increases design complexity. | Choose when deterministic FPU performance is prioritized over hardware configurability and ultra-low-power analog operation. |
Compared with CY8C4247AZI-M475, CY8C4248LQI-BL553 trades CAN for BLE and higher flash, while STM32F303VCT6 offers stronger compute but no reconfigurable analog/digital fabric - making the M475 optimal for mixed-signal, low-power, CAN-connected systems requiring field-tunable logic.

FAQ
Does CY8C4247AZI-M475 support hardware-based cryptographic acceleration?
No. This part does not include dedicated cryptographic engines (AES, SHA, TRNG) or secure boot features. It relies on software libraries for basic encryption tasks. For secure key storage or tamper-resistant operations, Infineon recommends the PSoC™ 6 series with ARM TrustZone and dedicated security subsystems.
What development tools are required to configure its programmable analog blocks?
The Infineon PSoC™ Creator IDE (v4.4 or later) is mandatory for schematic-based configuration of opamps, comparators, IDACs, and CSD blocks. It auto-generates initialization code and validates analog routing constraints - third-party tools like Keil or IAR support only post-configuration firmware development.
Can the 68-pin QFN package be hand-soldered reliably?
Yes, but with strict process control: use stencil-applied solder paste (type 4 or 5), preheat to 120°C, peak reflow at 245°C for ≤45 seconds, and verify thermal pad voiding <20% via X-ray. Hand-soldering is not recommended due to fine pitch (0.4 mm) and thermal pad requirements.
Is the 12-bit SAR ADC calibrated across temperature in production?
Yes. Each unit undergoes full-range gain/offset calibration at 25°C and –40°C during final test. The calibration coefficients are stored in flash and automatically applied by the PSoC™ Creator-generated ADC API - ensuring ±1 LSB INL over the full –40°C to +105°C range.
