Product details
Overview
CY8C4245PVS-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 1-Msps SAR ADC, opamp with comparator mode, and dual reconfigurable SCB peripherals supporting I²C/SPI/UART/LIN. It serves as a programmable mixed-signal system-on-chip for automotive body electronics and industrial control nodes requiring capacitive sensing and deep-sleep operation.
For engineers reviewing the CY8C4245PVS-482 datasheet, CY8C4245PVS-482 pinout, CY8C4245PVS-482 application, or CY8C4245PVS-482 equivalent, key selection criteria include AEC-Q100 qualification, on-chip CSD capacitive sensing engine with SmartSense auto-tuning, TCPWM kill signal support for motor safety, and dual SCBs enabling concurrent I²C sensor bus + UART diagnostics in a single chip.
Technical Context
The CY8C4245PVS-482 implements a tightly coupled mixed-signal architecture where the Arm Cortex-M0 core interfaces directly with programmable analog (CTBm opamp, SAR ADC, CSD) and digital (UDBs, TCPWM, SCBs) subsystems via a configurable interconnect matrix. Its clock system integrates IMO (48 MHz ±2%) and ILO (32.768 kHz) oscillators with automatic failover and SWD debug support.
Capacitive sensing is handled by the dedicated CSD block with sigma-delta modulation, delivering >5:1 SNR and water-tolerant operation without external components. The two SCBs operate independently-each can be runtime-reconfigured as I²C master/slave, SPI master/slave, UART, or LIN Slave 1.3/2.1-enabling heterogeneous peripheral integration without resource contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0 @ 48 MHz with single-cycle multiply - enables real-time control loops at ≤20.8 ns instruction cycle time. |
| Memory | 32 kB flash (with Read Accelerator) + 4 kB SRAM - supports firmware updates and buffered sensor data processing in Deep Sleep wake-up contexts. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended, channel sequencer with hardware averaging - delivers high-fidelity analog input for battery monitoring or thermistor reading. |
| Opamp | Reconfigurable CTBm block with external high-drive (50 mA) and internal high-bandwidth (10 MHz GBW) modes, plus comparator and ADC input buffering - eliminates need for external signal conditioning in current-sense or sensor front-ends. |
| CSD | Capacitive Sigma-Delta sensing engine with SmartSense auto-tuning - achieves robust touch detection under wet conditions using only PCB traces, no external ICs. |
| TCPWM | Four 16-bit Timer/Counter/PWM blocks with center-aligned, edge-aligned, and pseudo-random modes plus comparator-triggered Kill signals - meets ASIL-B functional safety requirements for motor gate drive control. |
| SCB | Two independent Serial Communication Blocks, each configurable as I²C/SPI/UART/LIN Slave - allows simultaneous sensor hub (I²C) and host interface (UART) without software arbitration. |
Pinout & Package
This device uses a 28-pin SSOP (Shrink Small Outline Package) with 0.635 mm pitch and exposed thermal pad. Pin functions are validated per Infineon datasheet 001-93573 Rev. *H Section 5.

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 QFN-56 package, Bluetooth LE radio integrated, 64 kB flash, 8 kB SRAM - adds wireless connectivity at cost of higher BOM and RF layout complexity. | Used where OTA firmware updates or smartphone pairing are required; not suitable for space-constrained SSOP layouts. | Select when wireless telemetry is mandatory and board area permits QFN-56; avoid if only wired communication is needed. |
| STM32F072CBT6 | ARM Cortex-M0, 48 MHz, 128 kB flash, 16 kB SRAM, but no integrated CSD or programmable analog - requires external touch controller and opamp for equivalent functionality. | Preferred in cost-sensitive industrial controls where capacitive sensing is absent and higher memory headroom is needed. | Choose when design already uses discrete analog signal chains and prioritizes flash size over integrated mixed-signal flexibility. |
Compared with CY8C4245PVS-482, CY8C4247LQI-BL483 adds Bluetooth but increases footprint and power; STM32F072CBT6 offers more memory but lacks on-chip CSD and analog configurability, increasing component count and layout effort for touch or precision analog tasks.

FAQ
What is the maximum operating temperature for CY8C4245PVS-482?
The CY8C4245PVS-482 is qualified to AEC-Q100 Grade 2, specifying continuous operation from −40 °C to +105 °C ambient temperature. This rating covers junction temperature limits under worst-case power dissipation and airflow conditions, validated per stress test requirements including HTOL and TC024.
Does CY8C4245PVS-482 support USB communication?
No, CY8C4245PVS-482 does not include a USB PHY or USB controller. Its serial communication capability is limited to two reconfigurable SCBs supporting I²C, SPI, UART, and LIN Slave protocols. USB functionality would require an external USB-to-UART bridge IC or a different PSoC family member such as PSoC 4 BLE with USB HID support.
Can the CSD block drive mutual-capacitance touch panels?
The CSD block in CY8C4245PVS-482 is optimized for self-capacitance sensing only, supporting up to 24 buttons/sliders via dedicated sigma-delta modulators. Mutual-capacitance scanning requires dedicated TX/RX channel pairs and timing control not implemented in this silicon revision; use CY8C4248LQI-BL553 or later PSoC 4100S Plus devices for mutual-capacitance support.
Is SWD debugging supported in Deep Sleep mode?
SWD debugging is disabled during Deep Sleep mode to minimize current draw; the debug interface resumes only after wake-up via GPIO, RTC alarm, or comparator event. To maintain debug visibility during low-power operation, use Hibernate mode instead - it retains SWD access while drawing ~1.5 µA and preserving RAM contents.
