Product details
Overview
CY8C4247LTI-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), segment LCD drive, dual CAN, and TCPWM for motor control in industrial HMI and automotive body electronics.
For engineers reviewing the CY8C4247LTI-M475 datasheet, CY8C4247LTI-M475 pinout, CY8C4247LTI-M475 application, or CY8C4247LTI-M475 equivalent, key selection criteria include Deep Sleep current (20 nA), SAR ADC performance (12-bit, 1-Msps), opamp count (4), UDB programmability, and CAN block integration for deterministic networking.
Technical Context
The device implements a tightly coupled MCU subsystem with DMA-accelerated data movement between peripherals and memory. Its analog subsystem includes four opamps supporting comparator mode and ADC input buffering, plus two low-power comparators that remain active in Deep Sleep - enabling wake-on-analog-event functionality without CPU intervention.
Digital flexibility stems from four Universal Digital Blocks (UDBs), each with 8 macrocells and an 8-bit datapath, allowing user-defined state machines or Verilog-based logic. Four reconfigurable Serial Communication Blocks (SCBs) support runtime switching among I²C, SPI, and UART protocols, while two dedicated CAN 2.0B controllers provide hardware message filtering and FIFO buffering for real-time industrial communication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz with single-cycle multiply - enables real-time control loops and firmware cryptography acceleration. |
| Flash Memory | 128 kB with Read Accelerator - reduces instruction fetch latency for deterministic ISR response in time-critical applications. |
| SRAM | 16 kB - sufficient for dual-buffered ADC acquisition, CAN message queues, and RTOS kernel stacks. |
| SAR ADC | 12-bit, 1-Msps - supports high-resolution sensor signal acquisition (e.g., thermistor, pressure transducer) with minimal external conditioning. |
| Opamps | 4 units, operational in Deep Sleep at ultra-low current - allows always-on analog front-end monitoring (e.g., battery voltage supervisor). |
| CAN Interfaces | 2 independent CAN 2.0B blocks - enables redundant bus architecture or multi-network topology (e.g., chassis + infotainment domains). |
| GPIO Count | Up to 55 programmable pins - supports mixed-signal routing for CAPSENSE™, LCD segments, analog inputs, and digital I/O simultaneously. |
Pinout & Package

| P2[5] | CAN1_TX | Dedicated transmit output for second CAN controller - supports slew-rate control to meet EMC emission limits in automotive environments. |
| P3[7] | VCSS (Voltage Reference) | Analog reference input for SAR ADC and opamp biasing - internally buffered and decoupled for stable conversion accuracy. |
| XRES | Active-Low Reset Input | Asynchronous reset pin with internal pull-up; accepts 1.71–5.5 V logic levels - enables external watchdog or power-monitor reset assertion. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LTI-BL553 | Same core architecture but with Bluetooth LE radio integrated; larger 128-pin QFN package and higher active power. | Requires wireless connectivity; unsuitable for EMI-sensitive motor control zones due to RF coexistence constraints. | Select when BLE telemetry or OTA firmware update capability is mandatory and RF isolation can be engineered. |
| STM32G474RET6 | Arm Cortex-M4F core, no programmable analog/digital fabric; fixed-function peripherals only; 512 kB flash, 128 kB SRAM. | Better floating-point math throughput but lacks CAPSENSE™, LCD drive, and UDB-level customization for mixed-signal adaptation. | Select for computationally intensive control algorithms where analog reconfiguration is unnecessary and memory headroom is critical. |
Compared with CY8C4247LTI-M475, CY8C4248LTI-BL553 adds wireless stack overhead and package complexity, while STM32G474RET6 trades hardware flexibility for raw processing power - making the M475 optimal for cost-constrained, mixed-signal embedded designs requiring field-adaptable analog/digital logic.

FAQ
Does CY8C4247LTI-M475 support USB device functionality?
No. This device does not include a USB PHY or USB controller. It features four SCBs configurable as I²C, SPI, or UART only. For USB connectivity, external bridge ICs (e.g., CP2102N) or migration to PSoC™ 4100S Plus with integrated USBFS are required.
What is the maximum operating frequency of the SAR ADC?
The SAR ADC achieves a maximum conversion rate of 1 Msps at 12-bit resolution. At lower resolutions (e.g., 8-bit), throughput increases to 2 Msps. Performance is guaranteed across the full –40°C to +105°C temperature range per datasheet Section 6.3.4.
Can the opamps be used as transimpedance amplifiers for photodiode signals?
Yes. Each opamp supports programmable gain and can be configured with external feedback components for transimpedance operation. Input bias current is 1 pA typical, and input common-mode range extends to VSS, enabling direct connection to photodiodes in zero-bias mode.
Is SmartSense tuning compatible with custom PCB layouts?
Yes. SmartSense auto-tuning adapts to parasitic capacitance variations caused by trace length, overlay thickness, and ground plane geometry. It operates using on-chip calibration registers and requires no layout-specific firmware changes - validated across >200 customer designs per Infineon application note AN92239.
