Product details
Overview
CY8C4245PVA-482ZT 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 programmable analog/digital blocks for capacitive sensing (CSD), PWM, and dual reconfigurable SCB peripherals supporting I²C/SPI/UART/LIN. It targets automotive body electronics requiring robust operation from −40 °C to +105 °C.
For engineers reviewing the CY8C4245PVA-482ZT datasheet, CY8C4245PVA-482ZT pinout, CY8C4245PVA-482ZT application, or CY8C4245PVA-482ZT equivalent, key selection criteria include AEC-Q100 qualification, on-chip CSD with SmartSense auto-tuning, deep-sleep comparator operation, TCPWM kill signal support, and dual SCB flexibility for mixed-protocol communication in space-constrained automotive modules.
Technical Context
The device 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 input buffering), two low-power comparators active in Deep Sleep, and two IDACs assignable to any GPIO for capacitive sensing or biasing.
Digital resources include four Universal Digital Blocks (UDBs) - each with 8 macrocells and data path - enabling custom logic or state machines, plus four 16-bit TCPWM blocks supporting center-aligned, edge-aligned, and pseudo-random PWM with hardware-triggered kill signals for motor control safety.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive-grade mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-BL483 | Same PSoC™ 4200 family, but with Bluetooth LE radio and 64 kB flash - adds wireless connectivity at higher cost and power. | Targets wireless diagnostics or OTA update-capable modules - not suitable where RF certification or antenna layout is prohibited. | Select only if BLE functionality is required; otherwise, CY8C4245PVA-482ZT offers lower BOM cost and simpler EMC validation. |
| SPC560B50L5 | Power Architecture-based MCU with e200z0 core, 1.5 MB flash, CAN FD, but no integrated capacitive sensing or programmable analog. | Designed for powertrain gateways - lacks CSD and UDBs, requiring external touch controller and analog ICs for body electronics. | Choose when CAN FD and ASIL-B safety certification are mandatory; avoid for cost-sensitive touch-centric designs. |
Compared with CY8C4247LQI-BL483, CY8C4245PVA-482ZT provides identical analog/digital flexibility without RF overhead, while versus SPC560B50L5 it delivers integrated capacitive sensing and reconfigurable logic - reducing component count and layout complexity in non-powertrain automotive modules.

FAQ
Is CY8C4245PVA-482ZT pin-compatible with other PSoC™ 4200 devices?
Yes - it shares the same 48-pin QFN package and pin mapping with CY8C4245AZI-483 and CY8C4247LQI-BL483, enabling hardware reuse across variants. However, firmware must be validated for peripheral register differences, especially SCB configuration and UDB resource allocation.
Does CY8C4245PVA-482ZT support CAN communication?
No - it does not integrate a CAN controller or transceiver. Communication is limited to I²C, SPI, UART, and LIN via its two SCB peripherals. For CAN-based automotive networks, external CAN transceivers with software-implemented protocol stacks or companion CAN MCUs are required.
What development tools are officially supported for this device?
Infineon's PSoC™ Creator IDE (legacy) and ModusToolbox™ 3.x+ fully support CY8C4245PVA-482ZT, including CAPSENSE™ Tuner, TCPWM configurator, and SCB component libraries. Hardware debugging requires KitProg3 or MiniProg4 programmers compatible with SWD interface.
How is AEC-Q100 qualification verified for this part number?
CY8C4245PVA-482ZT is certified to AEC-Q100 Grade 2 (−40 °C to +105 °C), with test reports covering HTOL, TC, ESD, and AC/DC parametric stability. Certification applies to the full device - not just the die - including package assembly and final test at Infineon's qualified automotive wafer and assembly sites.
