Product details
Overview
CY8C4245PVA-482 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), opamp with comparator mode, and dual reconfigurable SCB peripherals supporting I²C/SPI/UART/LIN. It enables capacitive touch sensing via CSD engine in automotive body control modules.
For engineers reviewing the CY8C4245PVA-482 datasheet, CY8C4245PVA-482 pinout, CY8C4245PVA-482 application, or CY8C4245PVA-482 equivalent, this device supports automotive-grade mixed-signal system-on-chip design with programmable analog/digital blocks, Deep Sleep operation, SmartSense auto-tuning, and TCPWM-based motor control timing.
Technical Context
The CY8C4245PVA-482 implements a tightly coupled MCU subsystem with single-cycle multiply Cortex-M0 core, IMO/ILO clock sources, and Power-on-Reset with Brown-Out detection. Its analog subsystem includes one opamp configurable for external drive or internal high-bandwidth buffering, two low-power comparators active in Deep Sleep, and a 12-bit SAR ADC with differential input and channel sequencer.
Digital resources include four Universal Digital Blocks (UDBs) for custom logic synthesis, two reconfigurable Serial Communication Blocks (SCBs) supporting concurrent I²C master/slave and SPI peripheral roles, and four 16-bit TCPWM blocks with center-aligned PWM, kill signal triggering, and pseudo-random modulation modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431KB | ARM Cortex-M4F core, 170 MHz, no integrated CSD engine; requires external touch controller IC. | Lacks hardware-accelerated capacitive sensing - unsuitable for cost-sensitive automotive touch interfaces requiring minimal BOM. | Select when floating-point math or higher CPU throughput is prioritized over integrated touch sensing. |
| RA4M2 (R7FA4M2AD) | ARM Cortex-M33 core, 100 MHz, includes capacitive touch IP but no LIN peripheral; AEC-Q100 Grade 2 only. | Missing LIN Slave 2.1/2.2 compliance - cannot replace CY8C4245PVA-482 in door module gateways requiring LIN physical layer integration. | Select for CAN-based body networks where LIN is not required and security features (TrustZone) are critical. |
Compared with STM32G431KB and RA4M2, CY8C4245PVA-482 uniquely integrates AEC-Q100-compliant CSD, LIN Slave, and TCPWM kill signaling in a single die - reducing system-level component count and qualification effort for automotive interior electronics.
