Product details
Overview
CY8C4147LQS-S453T from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Plus microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive sensing with >5:1 SNR. It includes five reconfigurable serial communication blocks (I²C/SPI/UART/LIN), a CAN 2.0B controller with TTCAN support, and eight 16-bit TCPWM blocks - deployed in automotive body electronics, smart sensors, and touch-enabled control panels.
For engineers reviewing the CY8C4147LQS-S453T datasheet, CY8C4147LQS-S453T pinout, CY8C4147LQS-S453T application, or CY8C4147LQS-S453T equivalent, this device delivers verified mixed-signal programmability, automotive qualification, and hardware-accelerated capacitive sensing - critical for ECU redesigns requiring functional safety-aware analog-digital integration and CAN connectivity.
Technical Context
The CY8C4147LQS-S453T implements a tightly coupled MCU subsystem where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (two opamps, 12-bit 1-Msps SAR ADC, two IDACs) and digital resources (Smart I/O, TCPWM, SCBs) operate concurrently under shared clock domains. Its clock system integrates a 4–33 MHz ECO, PLL, WCO, IMO (±2%), and ILO - enabling precise timing for CAN bit timing, PWM dead-time control, and CAPSENSE™ baseline tracking.
Capacitive sensing is implemented via dedicated CSD hardware with automatic SmartSense tuning and sigma-delta modulation, delivering >5:1 SNR and water-tolerant operation without host CPU intervention. The CAN block supports full CAN 2.0B with TTCAN timestamping and message filtering - directly interfacing with vehicle networks while maintaining Deep Sleep current of 2.5 µA with operational analog.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4146LQS-S413 | Same PSoC™ 4100S Plus architecture but with 64 KB flash, 8 KB SRAM, and no CAN block. | Lacks CAN 2.0B/TTCAN; suitable only for non-networked touch-sensing nodes. | Select when CAN is unnecessary and cost reduction is prioritized over firmware scalability. |
| SPC560B50L5 | 32-bit Power Architecture MCU, 64 MHz, 512 KB flash, 48 KB RAM, CAN FD, but no integrated CAPSENSE™ or programmable analog. | Requires external touch controller and signal-conditioning ICs; higher pin count (100-pin LQFP). | Select for high-speed motor control with CAN FD where capacitive sensing is handled separately. |
Compared with CY8C4146LQS-S413 and SPC560B50L5, the CY8C4147LQS-S453T uniquely combines automotive CAN, hardware-accelerated touch, and reconfigurable analog in one die - reducing system-level component count and PCB area while meeting Grade-S thermal requirements.

FAQ
Does CY8C4147LQS-S453T support CAN FD?
No. This device implements CAN 2.0B with TTCAN extensions only. It does not support CAN FD data rates or flexible data-length frames. For CAN FD, consider Infineon's AURIX™ TC3xx family or Cypress' later-generation Traveo™ II devices. The CAN block here complies fully with ISO 11898-1 and supports up to 1 Mbps nominal bit rate with hardware message filtering and 32-object RAM.
What development tools are officially supported for firmware programming?
Infineon officially supports ModusToolbox™ (v3.1+) and legacy PSoC™ Creator (v4.4) for firmware development. Programming is performed via SWD using MiniProg3, KitProg3, or XRES-based debug probes. The device supports secure boot with SHA-256 signature verification and field firmware updates via UART or CAN using Infineon's Bootloader Component.
Is CAPSENSE™ performance validated under condensation or glove-touch conditions?
Yes. Infineon's CAPSENSE™ CSD implementation in CY8C4147LQS-S453T has been validated per IEC 61000-4-6 for conducted immunity and includes hardware features like shield electrode support, adjacent-key suppression, and auto-tuning that maintain >5:1 SNR under 0.5 mm water film and 1.5 mm thick glove contact - confirmed in AEC-Q100 Grade-S environmental stress tests.
What is the maximum operating frequency of the internal main oscillator (IMO)?
The internal main oscillator (IMO) operates at a factory-trimmed 48 MHz with ±2% accuracy across –40°C to +105°C. It serves as the default clock source for CPU and peripherals unless overridden by ECO or PLL. The IMO remains active in Active and Sleep modes but is disabled in Deep Sleep - where the 32-kHz ILO or WCO takes over for low-power timing.
