Product details
Overview
CY8C4245PVA-482Z from Infineon is an AEC-Q100 qualified 32-bit Arm® Cortex®-M0 microcontroller with 48 MHz CPU, 32 kB flash, 4 kB SRAM, integrated 12-bit SAR ADC (1 Msps), and dual reconfigurable SCB peripherals supporting I²C/SPI/UART/LIN. It serves as a mixed-signal system-on-chip for automotive body electronics requiring capacitive touch sensing, PWM motor control, and low-power sensor interfacing.
For engineers reviewing the CY8C4245PVA-482Z datasheet, CY8C4245PVA-482Z pinout, CY8C4245PVA-482Z application, or CY8C4245PVA-482Z equivalent, this device delivers verified automotive-grade timing, analog signal acquisition, programmable digital logic (UDBs), CAPSENSE™-enabled HMI, and Deep Sleep–capable comparators - all in a 48-pin QFN package with 24 GPIOs.
Technical Context
The CY8C4245PVA-482Z implements a tightly coupled MCU subsystem with single-cycle multiply and Read Accelerator for deterministic flash execution. Its analog subsystem integrates one opamp (with comparator mode and ADC buffering), two low-power comparators active in Deep Sleep, and a CSD block enabling robust water-tolerant capacitive sensing.
Digital flexibility stems from four Universal Digital Blocks (UDBs), each containing eight macrocells and a data path, plus four TCPWM blocks supporting center-aligned PWM, kill-signal triggering, and hardware-based sequencing - all configurable via PSoC Creator without gate-level HDL.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz max - enables real-time control with <20 ns instruction cycle time at full speed. |
| Memory | 32 kB flash + 4 kB SRAM - supports firmware updates and runtime data logging without external memory. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended - captures fast transients (e.g., motor current, battery voltage) with hardware averaging. |
| CAPSENSE™ | CSD-based, >5:1 SNR, SmartSense auto-tuning - eliminates manual calibration for touch buttons/sliders in humid environments. |
| SCBs | 2 reconfigurable serial blocks - each can independently operate as I²C master/slave, SPI master/slave, UART, or LIN Slave 2.1/2.2. |
| TCPWM | 4 × 16-bit timer/counter/PWM blocks - support center-aligned PWM for motor drive and comparator-triggered fault shutdown. |
| GPIO | 24 programmable pins with analog/digital routing - enables flexible PCB layout and dynamic peripheral remapping in firmware. |
| Qualification | AEC-Q100 Grade 2 (−40°C to +105°C) - validated for under-hood and cabin automotive applications without derating. |
Pinout & Package
This device is housed in a 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are fully configurable via PSoC Creator's hardware abstraction layer, enabling dynamic routing of analog inputs, digital peripherals, and communication interfaces to any GPIO.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core power supply | 1.71–5.5 V input; powers digital logic, CPU, and SRAM - supports direct connection to 3.3 V or 5 V rails. |
| VSS | Ground reference | Primary digital/analog return path; must be connected to low-impedance ground plane for ADC/CAPSENSE™ integrity. |
| XRES | External reset input | Active-low asynchronous reset; internal pull-up ensures reliable startup without external components. |
| SWDCK / SWDIO | Debug interface | Two-pin Serial Wire Debug - enables programming, real-time tracing, and breakpoints without dedicated JTAG pins. |
| P0[0]–P0[7] | Programmable GPIO bank | Support analog input (ADC/CSD), digital I/O, SCB signals, or TCPWM outputs - routed automatically by design tool. |
| P1[0]–P1[7] | Programmable GPIO bank | Includes dedicated LCD segment/common drivers and high-current sink capability for LED indicators. |
Key Features
| Feature | Design Value |
|---|---|
| Reconfigurable UDBs | Four universal digital blocks enable custom state machines, counters, or glue logic - eliminating need for external CPLDs. |
| Deep Sleep comparators | Two ultra-low-power comparators remain active during Deep Sleep (≤1 µA total) - enabling wake-on-threshold events without CPU intervention. |
| CSD-based CAPSENSE™ | Hardware-accelerated sigma-delta sensing with >5:1 SNR and automatic SmartSense tuning - reduces firmware development time by >70% vs. raw ADC touch. |
| Flexible SCBs | Each serial block dynamically switches between I²C, SPI, UART, or LIN protocols at runtime - simplifies multi-interface designs with single hardware footprint. |
| Read Accelerator | Flash prefetch buffer with branch prediction - sustains 48 MHz CPU performance with zero wait states on sequential code execution. |
Applications
| Automotive Door Module | Smart HVAC Control Panel |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247AZI-M485 | Same PSoC 4200 family, but 68-pin TQFP, 64 kB flash, 8 kB SRAM, additional SCB and TCPWM resources. | Targeted at more complex automotive modules requiring multiple concurrent communication channels and larger firmware. | Select when scaling firmware size or adding LIN/I²C/SPI simultaneously without external bus arbitration. |
| SPC560B50L5 | Power Architecture-based, 64 MHz, 512 kB flash, ASIL-B certified, no integrated CAPSENSE™ or UDBs. | Used in safety-critical powertrain applications where ISO 26262 compliance is mandatory. | Choose only if functional safety certification (ASIL-B) is required - not a drop-in replacement due to architecture and peripheral mismatch. |
Compared with CY8C4245PVA-482Z, the CY8C4247AZI-M485 offers higher memory and I/O scalability for feature-rich modules, while the SPC560B50L5 addresses certified safety domains but lacks programmable analog/digital fabric - making the CY8C4245PVA-482Z optimal for cost-sensitive, non-safety automotive HMI and actuator control.

FAQ
Does CY8C4245PVA-482Z support CAN communication?
No. This device does not include a CAN controller or physical transceiver. It supports I²C, SPI, UART, and LIN via its two reconfigurable SCB peripherals. For CAN-based automotive networks, pairing with an external CAN transceiver (e.g., TJA1042) and software-implemented protocol stack is possible but not hardware-accelerated.
What development tools are required to program CY8C4245PVA-482Z?
Programming requires Infineon's PSoC Creator IDE (legacy) or ModusToolbox™ (current), a KitProg3 or MiniProg4 debugger, and a compatible development kit such as CY8CKIT-042-BLE or CY8CKIT-044. No external programmer is needed - SWD interface supports in-system programming and debug over two pins.
Is the internal opamp capable of driving external loads directly?
Yes - the integrated opamp supports high-drive external mode with up to ±25 mA output current and rail-to-rail operation. It can directly drive small solenoids, LEDs, or MOSFET gates without external buffers, though gain stability requires proper compensation per layout per the datasheet Figure 4-12.
How is AEC-Q100 qualification validated for this part?
CY8C4245PVA-482Z is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient), including stress tests for HTOL, TC, UHAST, ESD-HBM/MM, and latch-up. Full qualification reports are available under NDA from Infineon; the device carries the "AEC-Q100 Qualified" marking in its top-side laser print.
