Product details
Overview
CY8C4147LQE-S253 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Plus microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (SCBs), eight TCPWM modules, a CAN 2.0B controller with TTCAN support, and programmable analog blocks including two opamps and a 12-bit 1-Msps SAR ADC. Used in automotive body control modules requiring robust touch HMI and real-time motor timing.
For engineers reviewing the CY8C4147LQE-S253 datasheet, CY8C4147LQE-S253 pinout, CY8C4147LQE-S253 application, or CY8C4147LQE-S253 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAN 2.0B with time-triggered capability, Deep Sleep current of 2.5 µA, CAPSENSE™ SNR >5:1, and 54 GPIO with configurable drive strength and slew rate.
Technical Context
The device integrates a 48-MHz Arm® Cortex®-M0+ core with tightly coupled flash (Read Accelerator enabled) and SRAM, supporting deterministic real-time execution for automotive control loops. Its clock system combines a 4–33 MHz ECO, PLL, 32-kHz WCO, and ±2% IMO to enable precise timing across operating modes.
Programmable analog resources include two continuous-time opamps operable in Deep Sleep, a 12-bit SAR ADC with channel sequencer and signal averaging, and dual IDACs usable for CAPSENSE™ or general-purpose current sourcing. Digital flexibility is delivered via Smart I/O logic blocks and eight TCPWM units supporting center-aligned PWM, quadrature decoding, and comparator-triggered kill signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables deterministic real-time control with Thumb-2 instruction set and NVIC for automotive interrupt handling. |
| Memory | 128 KB flash (with Read Accelerator), 16 KB SRAM - supports secure bootloader storage, firmware updates, and runtime variable allocation without external memory. |
| Analog ADC | 12-bit SAR, 1 Msps, differential/single-ended, channel sequencer with signal averaging - delivers high-resolution sensor acquisition with noise suppression for automotive pressure/temperature sensing. |
| CAPSENSE™ | Capacitive sigma-delta (CSD) with SNR >5:1 and water tolerance - enables reliable touch buttons/sliders in humid cabin environments without mechanical wear. |
| CAN Interface | CAN 2.0B with time-triggered CAN (TTCAN) support - provides deterministic message scheduling and synchronization for distributed vehicle control networks. |
| Power Range | 1.71 V to 5.5 V operation, 2.5 µA Deep Sleep current - allows direct battery connection and ultra-low-power wake-on-touch or wake-on-CAN functionality. |

Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply domains | Independent 1.71–5.5 V supplies per port group - enables mixed-voltage interfacing (e.g., 3.3 V MCU logic with 5 V sensors). |
| P0[0]–P0[7], P1[0]–P1[7], etc. | Programmable GPIO | Each pin supports CAPSENSE™, analog input/output, digital logic, or SCB/CAN/TCPWM functions - no fixed peripheral pinout required. |
| XTAL_IN / XTAL_OUT | External crystal oscillator interface | Supports 4–33 MHz crystal for precise clock source - used for ECO-based system timing and CAN bit-rate accuracy. |
| CAN_TX / CAN_RX | Dedicated CAN transceiver interface | Direct connection to external CAN PHY (e.g., TJA1042) - implements ISO 11898-2 compliant physical layer signaling. |
| WCO_IN / WCO_OUT | 32-kHz watch crystal oscillator | Enables RTC operation and low-power wake-up timing independent of main clock - critical for sleep-mode event scheduling. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual tuning effort and maintains stable touch performance across temperature/humidity drift. |
| Deep Sleep with active analog | Opamps, comparators, and IDACs remain operational at 2.5 µA system current - enables always-on capacitive wake detection without MCU core wake-up. |
| Reconfigurable SCBs | Five serial blocks dynamically switch between I²C/SPI/UART/LIN slave modes at runtime - reduces BOM count and simplifies firmware-driven protocol adaptation. |
| TTCAN support | Time-triggered communication scheduling with guaranteed latency and jitter control - meets ASAM MCD-2 MC and AUTOSAR COM stack timing requirements. |
| Programmable Smart I/O | Boolean logic applied directly to GPIO inputs/outputs without CPU intervention - offloads simple state-machine tasks (e.g., LED blink patterns, fault latching) from firmware. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4146LQE-S243 | Same PSoC™ 4100S Plus family, but with 64 KB flash, 8 KB SRAM, and no CAN block. | Lacks CAN 2.0B/TTCAN; suitable only for non-networked automotive HMI or sensor nodes. | Select when CAN is unnecessary and cost reduction is prioritized over firmware scalability. |
| SPC560B50L5 | 32-bit Power Architecture e200z0 core, 512 KB flash, 48 KB RAM, dual CAN FD, but no integrated CAPSENSE™. | Requires external touch controller and higher BOM cost; better suited for engine control than touch-centric modules. | Choose for high-speed CAN FD networking where capacitive sensing is handled separately. |
Compared with CY8C4146LQE-S243 and SPC560B50L5, CY8C4147LQE-S253 uniquely combines AEC-Q100 Grade-S qualification, on-die CAPSENSE™ with SmartSense, and TTCAN in a single 48-pin QFN-enabling compact, certified automotive HMI designs without external timing or touch components.

FAQ
Does CY8C4147LQE-S253 support secure boot and cryptographic operations?
Yes. The device includes a True Random Number Generator (TRNG) for secure key derivation and supports hardware-accelerated AES-128 encryption via the PDL library. Secure boot is implemented through flash protection bits and checksum verification during reset, enabling trusted firmware loading per ISO/SAE 21434 cybersecurity requirements.
What development tools are officially supported for CY8C4147LQE-S253?
Infineon officially supports ModusToolbox™ (v3.1+) and PSoC™ Creator (v4.4). ModusToolbox™ provides Eclipse-based IDE, Peripheral Driver Library, CAPSENSE™ Tuner, and CAN configuration tools. PSoC™ Creator offers schematic-based hardware design with automatic analog/digital routing and component APIs for rapid prototyping.
Is CY8C4147LQE-S253 pin-compatible with other PSoC™ 4100S Plus devices?
No. While sharing the same 48-pin QFN footprint, pin functions differ across variants due to varying peripheral configurations (e.g., CAN_TX/RX presence, SCB count, analog block mapping). Pin mapping must be verified against the specific device's datasheet Table 2 "Pinouts" and "Alternate Pin Functions" section before layout.
How does the CAPSENSE™ implementation handle wet-finger operation?
The CSD sensing method achieves >5:1 signal-to-noise ratio and built-in water tolerance via shield electrode support, frequency hopping, and SmartSense auto-calibration. Wet-finger rejection is achieved through dynamic baseline tracking and adaptive threshold adjustment-validated per IEC 61000-4-6 immunity testing at 10 V/m conducted RF disturbance.
