Product details
Overview
CY8C4246LTI-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, four opamps with Deep Sleep operation, and capacitive sensing (CSD) with >5:1 SNR. It serves as a reconfigurable embedded controller in industrial HMI, motor control interfaces, and low-power sensor nodes.
For engineers reviewing the CY8C4246LTI-M475 datasheet, CY8C4246LTI-M475 pinout, CY8C4246LTI-M475 application, or CY8C4246LTI-M475 equivalent, key selection criteria include its dual CAN support, programmable UDB logic, SmartSense auto-tuning for CAPSENSE™, and 20-nA Stop Mode power consumption.
Technical Context
The device implements a tightly coupled architecture where the Arm® Cortex®-M0 core executes firmware while programmable analog blocks (opamps, comparators, 12-bit SAR ADC @ 1 Msps) and digital resources (four UDBs, eight TCPWM blocks) operate independently under hardware routing control. All analog peripherals retain functionality in Deep Sleep mode.
Its four Serial Communication Blocks (SCBs) support runtime reconfiguration between I²C, SPI, and UART protocols; two dedicated CAN 2.0B controllers enable industrial networking without external transceivers. The CSD engine uses sigma-delta modulation with hardware-accelerated baseline tracking and noise rejection.
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 loops and efficient firmware execution. |
| Memory | 128 kB flash (with Read Accelerator) + 16 kB SRAM - supports complex firmware with retained state during low-power modes. |
| Analog Peripherals | Four rail-to-rail opamps (Deep Sleep active), two low-power comparators, 12-bit SAR ADC @ 1 Msps - allows simultaneous signal conditioning, threshold detection, and high-speed sampling. |
| Digital Programmability | Four Universal Digital Blocks (UDBs), each with 8 macrocells and 8-bit datapath - provides hardware-level customization of logic, state machines, or protocol engines. |
| Low-Power Modes | 20-nA Stop Mode with GPIO wakeup, Deep Sleep with analog/digital retention - extends battery life in intermittent-sensing applications. |

| GPIO & Drive | Up to 55 programmable pins with configurable drive strength, slew rate, and CAPSENSE™/LCD/analog/digital roles - simplifies PCB layout and multi-function pin sharing. |
Pinout & Package
Package: 68-pin QFN (9 mm × 9 mm, 0.4 mm pitch), RoHS-compliant, thermally enhanced with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main supply input (1.71–5.5 V) | Power domain for digital core, SRAM, flash, and most peripherals; requires local decoupling. |

| XRES | External reset input | Active-low asynchronous reset with internal pull-up; debounced and synchronized to system clock. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning for electrode drift, temperature, and humidity. |
| Deep Sleep analog retention | Opamps, comparators, and ADC remain operational at sub-μA currents - enables continuous sensor monitoring without CPU wakeups. |
| UDB-based peripheral offload | Custom logic (e.g., encoder counting, PWM synchronization, protocol parsing) runs in hardware, freeing CPU cycles for application tasks. |
| Segment LCD direct drive | All GPIOs support LCD common/segment output with 4-bit memory per pin - eliminates external display driver IC in HMI designs. |
| Kill signal integration | TCPWM blocks trigger hardware-level kill signals via comparator outputs - ensures <100 ns fault response in motor control safety paths. |
Applications
| Industrial HMI Panels | Motor Control Interface Units |
|---|---|
|
Use Scenario: Touch-enabled operator panels in PLC cabinets with ambient moisture and EMI. IC Role / Device Role / Timing Role: Primary controller handling CAPSENSE™ buttons, segment LCD display, CAN bus communication with drive units, and real-time status reporting.

IC Role / Device Role / Timing Role: Safety-certifiable controller driving segmented LCD, validating CAPSENSE™ inputs against medical IEC 62366 usability requirements. Use Value: Hardware-based CAPSENSE™ baseline tracking meets IEC 60601 immunity thresholds; SRAM retention in Deep Sleep preserves session state during brief power loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LTI-M485 | Same package and core, but with 256 kB flash and 32 kB SRAM - no change in analog/digital peripheral count or CSD capability. | Better suited for firmware-over-the-air (FOTA) updates and larger RTOS deployments requiring code partitioning. | Select when future firmware growth or dual-bank flash update capability is required; pin-compatible drop-in upgrade. |
| STM32G474RET6 | Arm Cortex-M4F @ 170 MHz, 512 kB flash, 128 kB SRAM, but lacks integrated CAPSENSE™ and programmable analog/digital logic blocks. | Requires external components for capacitive sensing and custom logic, increasing BOM cost and board area. | Choose when floating-point math or higher CPU throughput dominates design priorities over hardware configurability and ultra-low-power analog retention. |
Compared with CY8C4246LTI-M475, the M485 offers scalable memory for evolving firmware while retaining identical peripheral functionality; the STM32G474 trades programmable analog/digital flexibility for raw CPU performance and larger memory, demanding external circuitry for equivalent sensing and logic capabilities.

FAQ
Does CY8C4246LTI-M475 support CAN FD?
No. CY8C4246LTI-M475 integrates two CAN 2.0B controllers compliant with ISO 11898-1:2003, supporting data rates up to 1 Mbps and standard/extended frame formats. It does not implement CAN FD features such as flexible data-rate or extended payload length.
What development tools are required to configure its programmable analog blocks?
Infineon's PSoC™ Creator IDE is required to graphically configure opamp routing, comparator thresholds, ADC sampling sequences, and CSD electrode parameters. The IDE generates API-ready code and validates hardware resource allocation before compilation.
Is the 68-pin QFN package lead-free and RoHS-compliant?
Yes. The CY8C4246LTI-M475 in 68-pin QFN packaging meets RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3), with lead-free matte tin terminations and halogen-free molding compound.
Can the internal opamps drive capacitive touch electrodes directly without external components?
Yes. The four opamps support dedicated CAPSENSE™ IDAC and CSD routing modes, enabling direct electrode drive and receive paths. No external opamp buffers or RC networks are needed for baseline CSD implementation per Infineon's AN92239 design guidelines.
