Product details
Overview
CY8C4245PVA-482T 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 delivers capacitive sensing via CSD engine with SmartSense auto-tuning and operates from 1.71 V to 5.5 V in automotive body control modules.
For engineers reviewing the CY8C4245PVA-482T datasheet, CY8C4245PVA-482T pinout, CY8C4245PVA-482T application, or CY8C4245PVA-482T equivalent, this device is selected for automotive-grade embedded control requiring mixed-signal integration, low-power Deep Sleep operation with comparator wake-up, and field-programmable analog/digital resources.
Technical Context
The CY8C4245PVA-482T implements a tightly coupled mixed-signal architecture where the Arm Cortex-M0 core interfaces directly with programmable analog blocks (opamp, SAR ADC, comparators) and digital UDBs. Its clock system integrates IMO (48 MHz) and ILO (32.768 kHz) oscillators, enabling precise timing control across sleep/wake transitions.
Capacitive sensing is handled by the dedicated CSD block with hardware-accelerated sigma-delta conversion, differential noise rejection, and automatic calibration-supporting up to 24 GPIOs as capacitive sense inputs without external components. The two SCBs operate independently and can be dynamically reconfigured at runtime for protocol switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0 @ 48 MHz with single-cycle multiply - enables real-time motor control and sensor fusion within tight interrupt latency budgets. |
| Memory | 32 kB flash (with Read Accelerator) + 4 kB SRAM - supports firmware updates in-field and retains critical state during low-power modes. |
| ADC | 12-bit SAR, 1 Msps, with channel sequencer & signal averaging - captures fast transients in battery monitoring or position sensing. |
| Capacitive Sensing | CSD engine with >5:1 SNR and water-tolerant operation - enables reliable touch buttons and sliders in humid automotive interiors. |
| Serial Interfaces | 2 × SCBs, each configurable as I²C/SPI/UART/LIN Slave 1.3/2.1/2.2 - eliminates need for external protocol translators in multi-bus vehicle networks. |
| Power Range | 1.71 V to 5.5 V supply - allows direct connection to 3.3 V or 5 V rails and compatibility with automotive battery voltage fluctuations. |
| Temperature Grade | AEC-Q100 Grade 2 (−40 °C to +105 °C) - certified for under-hood and cabin-mounted ECUs without derating. |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), thermally enhanced with exposed pad for automotive thermal reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main power supply input | Accepts 1.71–5.5 V; powers digital core, analog blocks, and I/O banks - requires local 100 nF decoupling per VDD pin. |
| VSS | Digital ground reference | Common return path for all digital logic and internal regulators - must be connected to low-impedance PCB ground plane. |
| XRES | External reset input | Active-low asynchronous reset; internal pull-up ensures valid startup without external resistor in most designs. |
| SWDCLK / SWDIO | Debug interface signals | Two-pin Serial Wire Debug port - enables full programming, breakpoint debugging, and real-time trace without dedicated JTAG pins. |
| P0[0]–P0[7] | Programmable GPIO bank | Supports analog input (ADC/CSD), digital I/O, and SCB functions - configured per-pin in PSoC Creator or ModusToolbox. |
| P1[0]–P1[7] | Programmable GPIO bank | Includes dedicated CSD shield and analog routing paths - used for high-SNR capacitive sensing electrode drive and receive. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CSD calibration adjusts baseline, sensitivity, and debounce in <10 ms - eliminates manual tuning across temperature and humidity gradients. |
| Deep Sleep with Comparator Wake | Consumes 1.3 µA typical while monitoring analog thresholds with two independent low-power comparators - extends battery life in always-on sensors. |
| Reconfigurable SCBs | Each SCB supports I²C master/slave, SPI master/slave, UART TX/RX, or LIN Slave 2.2 - reduces BOM count by consolidating communication peripherals. |
| UDB Programmable Logic | Four universal digital blocks (8 macrocells each) implement custom counters, state machines, or glue logic - avoids FPGA co-processor in cost-sensitive ECUs. |
| Integrated Opamp with ADC Buffer | Single opamp supports rail-to-rail output, comparator mode, and programmable gain - conditions sensor signals before SAR ADC sampling without external amplifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-BL483 | Same PSoC 4200 family, but with Bluetooth LE radio subsystem and 64 kB flash - adds RF stack overhead and higher active power. | Targets wireless diagnostics or OTA update capability - unnecessary if wired LIN/CAN is primary interface. | Select only when BLE connectivity is required; otherwise, CY8C4245PVA-482T offers lower cost and simpler certification path. |
| SPC560B50L3 | Power Architecture-based 32-bit MCU with 512 kB flash, but no integrated CSD or programmable analog - requires external touch controller and opamps. | Used in higher-tier powertrain applications - lacks hardware-accelerated capacitive sensing and consumes more board space. | Choose for ASIL-B functional safety compliance; avoid when capacitive HMI or analog integration is central to design. |
Compared with CY8C4247LQI-BL483 and SPC560B50L3, the CY8C4245PVA-482T uniquely balances automotive qualification, integrated CSD, and minimal BOM count - making it optimal for cost-constrained, sensor-rich body electronics where RF or ASIL-B are not required.

FAQ
Does CY8C4245PVA-482T support hardware-based AES encryption?
No. The CY8C4245PVA-482T does not include a cryptographic accelerator or hardware AES engine. Security relies on software-implemented algorithms or external secure elements. Its TRNG and flash protection features support basic secure boot, but full AES-128/256 acceleration requires higher-tier PSoC 4 devices like CY8C4248LQI-BL583.
What is the maximum operating frequency of the SAR ADC when oversampling is enabled?
When oversampling is enabled with 4× averaging, the effective sampling rate drops to 250 ksps while maintaining 12-bit resolution. The ADC's base conversion time remains fixed at 1 µs per sample; oversampling trades speed for improved SNR and reduced quantization noise - confirmed in Section 8.3.4 of the 001-93573 Rev. *H datasheet.
Can the opamp be used in unity-gain buffer mode with the SAR ADC input?
Yes. The integrated opamp supports unity-gain buffer configuration with rail-to-rail input/output and drives the SAR ADC input directly. This mode provides high-impedance signal conditioning and reduces sampling errors caused by source impedance - documented in Section 4.3.2 and validated in Figure 8-12 of the datasheet.
Is the SWD interface compatible with standard ARM CoreSight debug tools?
Yes. The SWDCLK and SWDIO pins implement ARM CoreSight Serial Wire Debug protocol compliant with ARM Debug Interface v5. It works with standard tools including Segger J-Link, ST-LINK/V2, and Infineon's KitProg3 - no proprietary firmware or adapter required for programming or real-time variable inspection.
