Product details
Overview
CY8C4245PVS-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 CapSense™ capacitive sensing engine - deployed in automotive body control modules for touch-sensitive door handles and climate panel interfaces.
For engineers reviewing the CY8C4245PVS-472ZT datasheet, CY8C4245PVS-472ZT pinout, CY8C4245PVS-472ZT application, or CY8C4245PVS-472ZT equivalent, this page delivers verified electrical specs, validated automotive-grade timing behavior, GPIO reconfiguration capability, and CapSense™ SNR performance metrics critical for EMI-resilient touch system design.
Technical Context
The device integrates a fixed-function Arm® Cortex®-M0 core with four programmable Universal Digital Blocks (UDBs), enabling custom state machines and peripheral logic without FPGA-level complexity. Its clock system includes a 48 MHz IMO and low-power 32.768 kHz ILO, supporting Deep Sleep wake-up via comparator or CapSense™ interrupt.
Analog subsystem features one opamp configurable as buffer, comparator, or ADC input driver; two low-power comparators active in Deep Sleep; and a 12-bit SAR ADC with hardware channel sequencer and signal averaging - all routed through a flexible interconnect matrix to any of 24 GPIOs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz max - enables real-time sensor fusion and deterministic PWM control in automotive sub-systems. |
| Memory | 32 kB flash + 4 kB SRAM - sufficient for OTA-capable firmware with CapSense™ tuning tables and LIN protocol stack. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended - supports high-resolution battery voltage monitoring and thermistor-based cabin temperature sensing. |
| CapSense™ Engine | CSD block with >5:1 SNR and SmartSense auto-tuning - delivers water-tolerant touch detection on plastic-over-metal surfaces in humid environments. |
| GPIO | 24 programmable pins with analog/digital/mixed-signal routing - allows shared pins for CapSense™ electrodes, PWM-driven LED indicators, and LIN bus communication. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-BL473 | Same PSoC™ 4200 platform, but with Bluetooth LE radio and 64 kB flash; higher package pin count (68-pin QFN). | Requires RF layout expertise and antenna integration; not suitable for cost-sensitive non-connectivity applications. | Select only when wireless telemetry or OTA updates are mandatory; adds $1.20 BOM cost and 3 mm² PCB area. |
| SPC560B50L5 | Power Architecture-based MCU; no CapSense™; 32-bit e200z0 core at 64 MHz; AEC-Q100 Grade 1 (−40 °C to +125 °C). | Lacks integrated capacitive sensing; requires external touch controller and signal chain components. | Prefer for high-temperature engine bay applications where CapSense™ is unnecessary and CAN FD is required. |
Compared with CY8C4245PVS-472ZT, CY8C4247LQI-BL473 adds wireless capability at cost and complexity premium, while SPC560B50L5 trades CapSense™ integration for higher thermal grade and CAN FD - making CY8C4245PVS-472ZT optimal for cost-constrained, touch-centric automotive interior modules.
