Product details
Overview
CY8C4245PVA-472Z from Infineon is an AEC-Q100 qualified 32-bit Arm® Cortex®-M0 microcontroller with integrated programmable analog (12-bit SAR ADC, opamp, dual comparators) and digital (UDBs, TCPWM, SCBs), operating from 1.71 V to 5.5 V and supporting up to 24 GPIOs. It delivers automotive-grade reliability in a 48-pin QFN package for body control, sensor fusion, and capacitive touch HMI applications.
For engineers reviewing the CY8C4245PVA-472Z datasheet, CY8C4245PVA-472Z pinout, CY8C4245PVA-472Z application, or CY8C4245PVA-472Z equivalent, this part supports hardware-accelerated CAPSENSE™, Deep Sleep–capable analog peripherals, reconfigurable serial interfaces (I²C/SPI/UART), and deterministic 48 MHz real-time control - critical for automotive interior electronics and industrial human-machine interfaces.
Technical Context
The device integrates a single-cycle multiply Arm Cortex-M0 CPU with 32 kB flash and 4 kB SRAM, coupled with a flexible routing matrix that enables dynamic interconnection of analog and digital resources. Its system-level timing includes IMO (48 MHz ±2%) and ILO (32.768 kHz) oscillators, Power-on-Reset with Brown-Out detection, and SWD debug interface.
Analog subsystem features include a rail-to-rail opamp configurable as buffer, comparator, or ADC input driver; two low-power comparators active in Deep Sleep; and a 12-bit SAR ADC with 1 Msps sampling, differential mode, and channel sequencer. Digital programmability is realized via four Universal Digital Blocks (UDBs), each with 8 macrocells and data path logic, enabling custom state machines or peripheral extensions.

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-483 | Same PSoC™ 4200 platform, 64-pin QFN, 64 kB flash, 8 kB SRAM, additional SCB and TCPWM resources. | Higher pin count and memory support more complex HMI + communication stacks (e.g., BLE + CAN + touch). | Select when scaling beyond 24 GPIOs or requiring dual concurrent protocols (e.g., I²C sensor hub + UART OTA update). |
| STM32G071KBT6 | Arm Cortex-M0+, 64 kB flash, 20 kB SRAM, no integrated CAPSENSE™ or programmable analog; requires external opamps/ADCs for similar analog functionality. | Suitable for cost-sensitive non-touch applications where analog integration is handled externally. | Select only if CAPSENSE™, hardware-accelerated analog, or AEC-Q100 qualification are not required. |
Compared with CY8C4245PVA-472Z, CY8C4247LQI-483 offers scalable resources for feature-rich automotive modules, while STM32G071KBT6 trades integrated analog flexibility for lower unit cost and simpler toolchain - but demands external components to match CY8C4245PVA-472Z's self-contained mixed-signal capability.

FAQ
What is the maximum operating temperature for CY8C4245PVA-472Z?
The device is qualified to AEC-Q100 Grade 2, with guaranteed operation from −40 °C to +105 °C ambient temperature. This rating applies to the full electrical specification including flash programming, analog performance, and GPIO drive strength - verified across temperature cycling and long-term reliability stress tests per JEDEC standards.
Does CY8C4245PVA-472Z support hardware-based capacitive touch without external components?
Yes. It integrates Infineon's CAPSENSE™ CSD engine with dedicated sigma-delta modulator, IDAC current sources, and SmartSense auto-tuning firmware - enabling fully self-contained touch button, slider, and proximity sensing on any GPIO without external RC networks or calibration firmware.
Can the opamp be used simultaneously with the SAR ADC?
Yes. The opamp can be configured as an ADC input buffer with programmable gain (1×, 2×, 4×, 8×), and its output connects directly to the ADC's analog mux. Both operate concurrently in active and Deep Sleep modes, with typical settling time <500 ns for 12-bit accuracy at 1 Msps sampling rate.
Is SWD debug supported in all power modes?
SWD debug is fully operational in Active and Sleep modes. In Deep Sleep, SWDCLK/SWDIO pins retain their debug function but require wake-up via XRES or GPIO interrupt before host communication resumes - consistent with ARM CoreSight requirements and Infineon's debug architecture documentation.
