Product details
Overview
CY8C4245AZI-M433 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 configurable analog/digital peripherals including four opamps, two comparators, a 12-bit SAR ADC (1 Msps), four IDACs, and eight TCPWM blocks - deployed in industrial HMI, capacitive touch interfaces, and low-power sensor nodes.
For engineers reviewing the CY8C4245AZI-M433 datasheet, CY8C4245AZI-M433 pinout, CY8C4245AZI-M433 application, or CY8C4245AZI-M433 equivalent, key selection criteria include Deep Sleep current (20 nA), CAPSENSE™ SNR (>5:1), reconfigurable SCBs (I²C/SPI/UART), CAN support, and 68-pin QFN package compatibility with GPIO-driven LCD and analog sensing.
Technical Context
The device implements a dual-domain architecture: a fixed-function Arm® Cortex®-M0 subsystem handles deterministic control tasks, while programmable analog (opamps, comparators, CSD engine) and digital (UDBs, TCPWM, SCBs) resources enable hardware-level customization without gate-level design. All analog blocks operate in Deep Sleep mode at sub-μA currents.
Its clock system integrates IMO (4–48 MHz), ILO (32.768 kHz), and external crystal sources; power management supports five low-power modes (Stop, Hibernate, Deep Sleep, Active, Sleep) with pin- or timer-triggered wake-up. The CSD engine uses sigma-delta modulation with SmartSense auto-tuning for robust water-tolerant touch sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz - enables real-time control with single-cycle multiply for motor timing and sensor fusion. |
| Memory | 128 kB flash + 16 kB SRAM - sufficient for bootloader, CapSense firmware, and multi-peripheral RTOS deployment. |
| ADC | 12-bit SAR, 1 Msps - supports high-speed analog monitoring (e.g., battery voltage, temperature, current sense). |
| Low-Power Modes | 20 nA Stop Mode with GPIO wakeup - extends battery life in portable HMI and wireless sensor endpoints. |
| CAPSENSE™ | Sigma-delta CSD with >5:1 SNR and water tolerance - delivers reliable touch detection on wet or gloved surfaces. |
| Communication | 4 × SCBs (reconfigurable I²C/SPI/UART) + 2 × CAN - enables mixed-protocol industrial networking and diagnostics. |
| Timing | 8 × 16-bit TCPWM blocks with center-aligned/PWM kill signals - suitable for BLDC motor control and LED dimming. |
Pinout & Package
Package: 68-pin QFN (10 mm × 10 mm, 0.5 mm pitch), RoHS-compliant, thermally enhanced with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core & I/O supply | 1.71–5.5 V input; powers all digital logic, analog blocks, and GPIO drivers. |
| VSS | Digital ground | Reference return path for core logic and digital peripherals. |
| VREF | Analog reference | Configurable internal/external reference for ADC, DAC, and comparator accuracy. |
| XRES | Active-low reset | Asynchronous hardware reset with internal pull-up; debounced externally for ESD immunity. |

| P0[0]–P0[7] | Programmable GPIO | Support CAPSENSE™, LCD segment/common, analog input/output, or digital logic with configurable drive strength. |
Key Features
| Feature | Design Value |
|---|---|
| Reconfigurable UDBs | Four universal digital blocks (8 macrocells each) allow custom state machines or glue logic without FPGA toolchain. |
| Deep Sleep Analog | Opamps and comparators remain active at ≤1 μA - enables always-on touch wake-up without MCU intervention. |
| SmartSense Auto-Tuning | Hardware-accelerated CSD calibration adjusts baseline and sensitivity dynamically - eliminates manual tuning across temperature/humidity. |
| LCD Direct Drive | All GPIO pins support segment/common LCD driving in Deep Sleep - reduces BOM by eliminating external display controllers. |
| Flexible SCBs | Each serial block can be runtime-reconfigured as I²C master/slave, SPI master/slave, or UART - simplifies protocol migration and reuse. |
Applications
| Industrial HMI Panel | Capacitive Touch Remote |
|---|---|
Use Scenario: Wall-mounted control panel in factory automation with touch buttons, status LEDs, and CAN bus integration. IC Role / Device Role / Timing Role: Central controller managing CAPSENSE™ inputs, LED PWM dimming, CAN diagnostics, and real-time alarm logging.

IC Role / Device Role / Timing Role: Timing controller generating center-aligned PWM with comparator-triggered kill signals to halt output on fault. Use Value: Hardware-based fault response (<100 ns latency) ensures IGBT safety compliance without software interrupt overhead. |
Use Scenario: Wireless environmental sensor node measuring temperature, humidity, and ambient light with local processing. IC Role / Device Role / Timing Role: Signal conditioner (opamp buffering), ADC digitizer, and data preprocessor before RF transmission. Use Value: On-chip opamps and SAR ADC eliminate external signal chain components, improving measurement repeatability and reducing layout sensitivity. |
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 |
|---|---|---|---|
| CY8C4247AZI-M485 | Higher flash (256 kB) and SRAM (32 kB); same package and peripheral set. | Better suited for complex CapSense+BLE stacks or larger RTOS deployments. | Select when firmware size exceeds 128 kB or multi-threaded operation requires >16 kB RAM. |
| STM32L433RCT6 | No integrated CapSense or programmable analog; includes AES crypto and USB FS. | Lacks hardware touch engine and configurable opamp routing - requires external components for robust touch. | Prefer when security features dominate over analog flexibility, and touch is implemented via external IC or simplified overlay. |
Compared with CY8C4245AZI-M433, the CY8C4247AZI-M485 offers headroom for future firmware expansion without changing layout, while the STM32L433RCT6 trades analog configurability for cryptographic acceleration and USB connectivity - making it less optimal for cost-sensitive, analog-rich HMI designs.

FAQ
Does CY8C4245AZI-M433 support CAN FD?
No. This device integrates two classical CAN 2.0B controllers operating up to 1 Mbps, but lacks CAN FD frame format support, arbitration bit rate extension, or flexible data field length. For CAN FD, consider Infineon's TRAVEO™ T2G or newer PSoC™ 6 families with dedicated FD-capable peripherals.
What development tools are required for PSoC™ Creator projects?
PSoC™ Creator IDE (v4.4 or later) is mandatory for schematic-based design, automatic analog/digital routing, and component-based API generation. It requires Windows OS and supports programming via KitProg2/MiniProg4 debug probes. Arm GCC toolchain is embedded; no third-party IDE license is needed for basic firmware builds.
Can all GPIO pins drive LCD segments in Deep Sleep mode?
Yes. All 55 GPIOs support LCD segment/common drive with 4-bit memory retention in Deep Sleep mode, enabling static display updates without waking the CPU. Segment mapping is fully configurable in PSoC™ Creator, and contrast is adjustable via internal bias voltage generators.
Is the 12-bit SAR ADC capable of simultaneous sampling across multiple channels?
No. The SAR ADC has a single conversion core with multiplexed inputs; it performs sequential sampling at up to 1 Msps per channel. Simultaneous sampling requires external synchronized ADCs or devices with multiple independent SAR cores, such as PSoC™ 6's dual ADC configuration.
