Product details
Overview
CY8C4147LQE-S293T 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 (SCB), eight 16-bit TCPWM units, a CAN 2.0B controller with TTCAN support, and programmable analog resources including two opamps and a 12-bit 1-Msps SAR ADC - deployed in body control modules and touch-enabled automotive HMI systems.
For engineers reviewing the CY8C4147LQE-S293T datasheet, CY8C4147LQE-S293T pinout, CY8C4147LQE-S293T application, or CY8C4147LQE-S293T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR >5:1 with water tolerance, CAN 2.0B + TTCAN timing compliance, Deep Sleep current of 2.5 µA, and GPIO flexibility across 54 pins with configurable drive strength and slew rate.
Technical Context
The device implements a tightly integrated mixed-signal SoC architecture where the Arm® Cortex®-M0+ core coordinates programmable digital logic (Smart I/O, TCPWM), reconfigurable analog blocks (CTB opamps, SAR ADC, IDACs), and fixed-function peripherals (CAN, SCB, WCO/ECO oscillators). Its clock system combines a ±2% IMO, 32-kHz ILO, 32-kHz WCO, and 4–33 MHz ECO with PLL-based 48-MHz system clock generation.
Capacitive sensing is implemented via a dedicated CSD block supporting sigma-delta modulation, hardware-accelerated SmartSense tuning, and differential noise rejection - enabling robust touch detection under wet conditions. The CAN block supports time-triggered operation with programmable bit timing, error counters, and message buffers compliant with ISO 11898-1.

FAQ
Does CY8C4147LQE-S293T support secure boot and cryptographic operations?
Yes. It integrates a true random number generator (TRNG) for secure key derivation and supports AES-128 encryption via software libraries in ModusToolbox™. While it lacks a dedicated hardware crypto accelerator, the TRNG and flash protection mechanisms enable secure bootloader implementation meeting ISO/SAE 21434 threat mitigation requirements for entry-level automotive ECUs.
What development tools are officially supported for this device?
Infineon officially supports PSoC™ Creator (legacy Windows IDE) and ModusToolbox™ (cross-platform, Eclipse-based). Both provide full peripheral configuration, CAPSENSE™ tuning GUI, CAN bit-timing calculators, and debug via KitProg3 or MiniProg4. Third-party tools like Keil MDK and IAR Embedded Workbench are compatible via Arm® CMSIS-Pack support.
Can the on-chip opamps be used for sensor signal conditioning in automotive environments?
Yes. The two continuous-time opamps operate down to 1.71 V, support rail-to-rail output, and remain functional in Deep Sleep mode. They are characterized across –40°C to +105°C with input offset drift <2 µV/°C - validated for use with thermistors, RTDs, and bridge sensors in cabin temperature or seat occupancy detection systems.
Is external flash memory required for firmware updates in the field?
No. With 128 KB on-chip flash and Read Accelerator, the device supports dual-bank firmware update schemes. The PDL includes verified bootloader examples that validate new images before switching banks - enabling safe over-the-air (OTA) updates without external memory or risk of bricking.
