Product details
Overview
CY8C4147LQA-S253T 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 touch-sensing with SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (SCB), CAN 2.0B with TTCAN support, and eight 16-bit TCPWM modules-used in automotive body control modules requiring robust touch HMI and motor timing.
For engineers reviewing the CY8C4147LQA-S253T datasheet, CY8C4147LQA-S253T pinout, CY8C4147LQA-S253T application, or CY8C4147LQA-S253T equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-die CAPSENSE™ SNR >5:1, CAN 2.0B + TTCAN compliance, Deep Sleep current of 2.5 µA, and programmable analog/digital routing for mixed-signal integration without external components.
Technical Context
The device implements a tightly coupled MCU subsystem with 48-MHz Arm® Cortex®-M0+ core, 128 KB flash with Read Accelerator, and 16 KB SRAM. Its analog subsystem integrates two opamps (supporting ADC input buffering and Deep Sleep operation), a 12-bit 1-Msps SAR ADC with channel sequencer, and a dedicated capacitance-sensing block enabling sigma-delta CSD with >5:1 SNR.
Digital resources include five SCBs supporting I²C/SPI/UART/LIN, one CAN 2.0B block with time-triggered capability, eight TCPWM blocks with quadrature decode and comparator-triggered kill signals, and Smart I/O logic for Boolean port-level operations-all routed via automatic digital interconnect fabric.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - enables real-time deterministic control with Thumb-2 instruction set and NVIC-based interrupt handling. |
| Flash / SRAM | 128 KB flash with Read Accelerator; 16 KB SRAM - supports firmware updates over CAN/LIN and retains critical variables during low-power modes. |
| Operating Temp | Grade-S: –40°C to +105°C - qualified per AEC-Q100 Rev G for under-hood automotive applications including junction box controllers. |
| CAPSENSE™ | Capacitive sigma-delta (CSD) with SmartSense auto-tuning and >5:1 SNR - delivers water-tolerant touch buttons/sliders without manual calibration. |
| CAN Interface | CAN 2.0B with Time-Triggered CAN (TTCAN) - supports synchronized message scheduling for safety-critical actuator control loops. |
| Low-Power Modes | Deep Sleep mode draws 2.5 µA system current with opamps and comparators active - enables always-on touch wake-up with sub-3 ms latency. |
| GPIO Count | Up to 54 programmable pins across QFN/TQFP packages - any pin supports CAPSENSE™, analog, or digital functions with configurable drive strength/slew rate. |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, wettable flank option available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply domains | Independent 1.71–5.5 V domains enable mixed-voltage interface (e.g., 3.3 V MCU core + 5 V sensor bus). |
| P0[0]–P0[7], P1[0]–P1[7], etc. | Programmable GPIO banks | Each pin supports CAPSENSE™, analog input/output, digital logic, or SCB/CAN function - assigned dynamically in PSoC™ Creator. |
| CAN_TX / CAN_RX | Dedicated CAN physical layer interface | Internal termination and slew-rate control meet ISO 11898-2 requirements; no external transceiver needed for basic node testing. |
| XTAL_IN / XTAL_OUT | External crystal oscillator inputs | Supports 4–33 MHz ECO for precise clocking; PLL derives 48 MHz system clock with ±0.25% jitter at 100 kHz offset. |
| WCO_IN / WCO_OUT | 32.768 kHz watch crystal interface | Enables RTC operation and Deep Sleep wake-up timing independent of main clock domain. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated CAPSENSE™ with SmartSense | Hardware-accelerated auto-tuning eliminates manual calibration effort and maintains stable touch performance across temperature/humidity drift. |
| Five reconfigurable SCBs | Single hardware block can be runtime-switched between I²C master/slave, SPI master/slave, UART, or LIN slave - reduces BOM count and PCB footprint. |
| TTCAN support | Time-triggered scheduling allows deterministic message transmission windows essential for ASIL-B functional safety architectures. |
| Programmable analog routing | Opamp outputs and ADC inputs connect directly to GPIOs or internal digital logic without external traces - minimizes noise coupling in mixed-signal designs. |
| True Random Number Generator (TRNG) | Meets NIST SP 800-90B entropy requirements for secure key generation in automotive OTA update authentication. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144HAT0MLHT | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC and FlexRay; larger flash (1 MB); no integrated CAPSENSE™ | Targeted at gateway ECUs requiring high-speed networking; lacks on-die touch sensing - requires external touch controller | Select when Ethernet/FlexRay or higher compute throughput is required; avoid if touch HMI integration is primary goal |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; 512 KB flash; built-in touch voltage detection (not sigma-delta); no CAN FD or TTCAN | Cost-sensitive entry-level body electronics; limited SNR (<3:1) and no water-tolerance certification | Choose for non-safety-critical interior switches where BOM cost dominates; not suitable for ASIL-B or wet-environment use |
Compared with S32K144HAT0MLHT and RL78/F14, CY8C4147LQA-S253T uniquely combines AEC-Q100 Grade-S qualification, hardware-accelerated CAPSENSE™ with SmartSense, TTCAN, and sub-3 ms touch latency - making it optimal for compact, safety-aware touch HMI nodes where analog/digital integration reduces system complexity.

FAQ
Does CY8C4147LQA-S253T require an external CAN transceiver?
Yes - while the device contains a CAN 2.0B controller with TTCAN support, it lacks a physical layer (PHY). An external ISO 11898-2 compliant transceiver (e.g., Infineon TLE6250 or TI SN65HVD230) is required for bus connection. The CAN_TX/CAN_RX pins provide differential logic-level signals compatible with standard transceivers.
What development tools support CAPSENSE™ tuning for this part?
PSoC™ Creator v4.4+ and ModusToolbox™ v3.1+ provide full CAPSENSE™ configuration, real-time tuning via CapSense Tuner utility, and SmartSense auto-calibration export. Hardware debugging requires MiniProg3 or KitProg3 programmer/debugger connected to SWD interface pins.
Is the 12-bit SAR ADC usable during Deep Sleep mode?
No - the 12-bit SAR ADC is disabled in Deep Sleep. However, the dedicated capacitance-sensing block (CSD) remains fully operational, enabling continuous touch scanning at 2.5 µA system current. For analog sensor monitoring in low-power states, the low-power comparators or IDAC-based sigma-delta measurement must be used instead.
How many simultaneous SCB instances can operate concurrently?
All five SCB blocks can operate simultaneously - each independently configured as I²C, SPI, UART, or LIN slave. No resource contention occurs because each SCB has dedicated FIFOs, clock dividers, and interrupt vectors. Concurrent operation is validated in PSoC™ Creator's resource meter and confirmed in the Architecture TRM Section 1.5.2.
