Product details
Overview
CY8C4245PVA-472ZT 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 1-Msps SAR ADC, and dual reconfigurable SCB peripherals supporting I²C/SPI/UART/LIN. It serves as a programmable mixed-signal system-on-chip for automotive body electronics requiring capacitive touch sensing, PWM motor control, and low-power deep-sleep operation.
For engineers reviewing the CY8C4245PVA-472ZT datasheet, CY8C4245PVA-472ZT pinout, CY8C4245PVA-472ZT application, or CY8C4245PVA-472ZT equivalent, key selection criteria include AEC-Q100 qualification, on-chip CSD-based capacitive sensing SNR >5:1, Deep Sleep current <1 µA with comparator wake-up, TCPWM kill-signal triggering, and UDB-based digital logic reconfiguration without firmware update.
Technical Context
This device implements a tightly coupled mixed-signal architecture where the Arm Cortex-M0 core orchestrates programmable analog (opamp, SAR ADC, IDACs, comparators) and digital (UDBs, TCPWM, SCBs) subsystems via configurable interconnect routing. All analog blocks operate down to 1.71 V and retain functionality in Deep Sleep mode.
The two Serial Communication Blocks (SCBs) support runtime reconfiguration between I²C, SPI, UART, and LIN Slave 1.3/2.1/2.2 modes - each with independent clocking and DMA support. Four TCPWM blocks provide center-aligned PWM with hardware-triggered kill inputs for motor safety, while SmartSense auto-tunes CSD sensor parameters without host CPU intervention.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560B50L3 | Power Architecture e200z0 core, 64 MHz, 512 kB flash, no integrated CSD or UDBs - relies on external touch controller and FPGA-like logic. | Targets higher-tier powertrain and chassis systems requiring ASIL-B compliance; lacks automotive-grade capacitive sensing IP. | Select when functional safety certification (ISO 26262) is mandatory and CSD is handled externally. |
| RA4M1 (R7FA4M1AB) | Arm Cortex-M4F @ 48 MHz, 256 kB flash, 32 kB SRAM, no CSD engine or UDBs - uses software-based touch libraries and standard peripherals only. | Optimized for general-purpose industrial HMI with USB and Ethernet; requires external components for robust wet-touch operation. | Select when floating-point math or larger memory is needed, and capacitive sensing is secondary or implemented via external IC. |
Compared with SPC560B50L3 and RA4M1, CY8C4245PVA-472ZT uniquely integrates AEC-Q100-qualified CSD, UDB-based hardware logic, and sub-1 µA Deep Sleep with comparator wake-up - making it optimal for cost-sensitive, space-constrained automotive body electronics where touch, PWM, and ultra-low-power operation are co-located on one die.

FAQ
Is CY8C4245PVA-472ZT qualified for automotive use?
Yes. CY8C4245PVA-472ZT is fully qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient), including stress testing for thermal cycling, humidity, and mechanical shock. It supports automotive power supply profiles including cold crank (4.5 V min) and load dump (40 V transient), and includes built-in POR, brown-out detection, and watchdog timer for fail-safe operation.
Does this part support capacitive touch sensing without external components?
Yes. The integrated CapSense™ Sigma-Delta (CSD) engine supports self- and mutual-capacitance sensing directly on any GPIO pin, with hardware-accelerated SmartSense auto-tuning. No external RC networks, shield drivers, or dedicated touch controllers are required - enabling button, slider, and proximity sensing with >5:1 SNR and water tolerance.
What development tools are supported for firmware and hardware configuration?
Infineon's PSoC™ Creator IDE (legacy) and ModusToolbox™ (current) fully support CY8C4245PVA-472ZT. Both provide graphical peripheral configurators for TCPWM, SCB, CSD, and UDB logic, along with pre-verified CapSense and communication middleware. Hardware debugging uses standard 2-pin SWD via KitProg3 or MiniProg4 programmers.
Can the opamp and ADC be used simultaneously for current sensing?
Yes. The integrated opamp can be configured in non-inverting mode with gain up to 16× to amplify shunt voltage, and its output is directly routable to the SAR ADC's input channel. This enables closed-loop motor current monitoring with 12-bit resolution and 1 Msps sampling - all within a single chip and without external signal conditioning components.
