Product details
Overview
CY8C4245PVS-472Z from Infineon is an AEC-Q100 qualified 32-bit Arm® Cortex®-M0 microcontroller with 32 kB flash, 4 kB SRAM, and integrated programmable analog/digital blocks for automotive-grade embedded control. It delivers 48 MHz CPU performance, 12-bit 1-Msps SAR ADC, two low-power comparators, and CapSense™ capacitive sensing-enabling robust touch interfaces in engine control units and body electronics.
For engineers reviewing the CY8C4245PVS-472Z datasheet, CY8C4245PVS-472Z pinout, CY8C4245PVS-472Z application, or CY8C4245PVS-472Z equivalent, key selection criteria include AEC-Q100 qualification, reconfigurable UDB-based digital logic, CSD-based water-tolerant touch sensing, and dual SCB peripherals supporting I²C/SPI/UART/LIN in automotive subsystems.
Technical Context
The device integrates a 48 MHz Arm Cortex-M0 CPU with single-cycle multiply, supported by up to 32 kB flash (with Read Accelerator) and 4 kB SRAM. Its system-level timing relies on dual oscillators: a 48 MHz IMO and a 32.768 kHz ILO enabling Deep Sleep operation with wake-on-comparator events.
Analog functionality centers on a reconfigurable opamp (CTBm block) supporting comparator mode and ADC input buffering, plus two IDACs for CapSense™ current sourcing. Digital flexibility comes from four Universal Digital Blocks (UDBs), each with 8 macrocells and data path, enabling custom state machines or peripheral logic without FPGA-level complexity.

Key Features
| Feature | Design Value |
|---|---|
| Reconfigurable UDBs | Four universal digital blocks enable hardware-accelerated logic (e.g., custom CRC, pulse counting, or protocol parsing) without CPU overhead. |
| CapSense™ CSD | Hardware sigma-delta modulator with >5:1 SNR and automatic SmartSense tuning - eliminates manual electrode calibration across production batches. |
| Deep Sleep with Analog Wake | Two low-power comparators remain active in Deep Sleep, triggering wake on threshold crossing - extends battery life in always-on vehicle entry systems. |
| Flexible SCB Peripherals | Each SCB dynamically reconfigures between I²C master/slave, SPI master/slave, UART, or LIN Slave - reduces BOM count in multi-interface ECUs. |
| Opamp with ADC Buffering | Single opamp supports comparator mode, high-drive external output, and internal buffering of ADC inputs - enables precision sensor signal conditioning in one block. |
Applications
| Automotive Door Module | Engine Control Unit (ECU) Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-483 | Same PSoC 4200 family, but 48-pin QFN package with higher GPIO count (34 vs. 24) and additional SCB (3 vs. 2). | Preferred for designs needing more I/O for multi-sensor fusion or expanded CAN/I²C bus bridging. | Select when board layout allows QFN and application requires ≥30 GPIOs or triple-protocol SCB redundancy. |
| SPC560B50L5 | Power Architecture-based 32-bit MCU, AEC-Q100 Grade 1 (–40 °C to +125 °C), no programmable analog/digital blocks. | Targeted at higher-temperature engine control where reconfigurability is secondary to extreme thermal resilience. | Choose only if operating ambient exceeds +105 °C or ASIL-B certification requires Power Architecture toolchain validation. |
Compared with CY8C4245PVS-472Z, CY8C4247LQI-483 offers greater I/O scalability while retaining identical CapSense™ and UDB capabilities, whereas SPC560B50L5 trades programmable analog/digital flexibility for higher-temperature operation and legacy Power Architecture ecosystem alignment.

FAQ
Does CY8C4245PVS-472Z support CAN communication?
No. The CY8C4245PVS-472Z does not integrate a CAN controller or physical layer. It features two Serial Communication Blocks (SCBs) configurable only for I²C, SPI, UART, or LIN Slave protocols. For CAN-based automotive networks, external CAN transceivers paired with UART-based software stacks or migration to Infineon's AURIX™ family is required.
What debug interface does CY8C4245PVS-472Z use?
CY8C4245PVS-472Z uses a two-pin Serial Wire Debug (SWD) interface via dedicated SWDCLK and SWDIO pins. This supports full JTAG-equivalent debugging, flash programming, and real-time variable monitoring using Infineon's ModusToolbox™ IDE and compatible CMSIS-DAP debug probes.
Is the CapSense™ implementation hardware-accelerated?
Yes. CapSense™ uses a dedicated hardware sigma-delta modulator (CSD block) with built-in IDACs, integrators, and digital filtering. Signal processing-including baseline tracking, noise rejection, and finger detection-is performed in hardware, offloading the CPU and ensuring consistent 10-ms scan times across all electrodes.
Can the opamp operate in Deep Sleep mode?
No. The opamp (CTBm block) is disabled in Deep Sleep mode. However, the two low-power comparators remain active and can be configured to monitor external analog signals, generating interrupts or wake events without CPU intervention-enabling ultra-low-power wake-on-event functionality.
