Product details
Overview
CY8C4147AZE-S295T 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 a CAN 2.0B block with TTCAN support, five reconfigurable SCBs (I²C/SPI/UART/LIN), and eight TCPWM blocks - deployed in automotive body control modules, smart sensors, and touch-enabled cockpit interfaces.
For engineers reviewing the CY8C4147AZE-S295T datasheet, CY8C4147AZE-S295T pinout, CY8C4147AZE-S295T application, or CY8C4147AZE-S295T 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, programmable analog (opamps, 12-bit 1-Msps SAR ADC, IDACs), and CAPSENSE™ hardware acceleration with SmartSense auto-tuning.
Technical Context
The device integrates a hardened automotive timing architecture with dual clock domains: a 48-MHz system clock derived from PLL+ECO or IMO, and independent low-power clocks (WCO, ILO) enabling concurrent operation of CAPSENSE™ and real-time peripherals in Deep Sleep. Its CAN block implements full CAN 2.0B with TTCAN-compliant synchronization and error confinement for safety-critical messaging.
Programmable analog resources include two continuous-time opamps supporting ADC input buffering and comparator modes, plus a dedicated capacitance-sensing sigma-delta (CSD) block delivering >5:1 SNR and water-tolerant touch performance. Digital logic is implemented via Smart I/O blocks and eight TCPWM units with quadrature decode and comparator-triggered kill signals for motor control.

FAQ
Does CY8C4147AZE-S295T support CAN FD?
No. CY8C4147AZE-S295T implements CAN 2.0B with optional time-triggered CAN (TTCAN) support, but does not include CAN FD protocol features such as flexible data rate or extended payload length. It complies with ISO 11898-1:2015 for classical CAN only.
What is the maximum operating frequency of the internal main oscillator (IMO)?
The internal main oscillator (IMO) is factory-trimmed to ±2% accuracy at 48 MHz and can be used directly as the system clock source. It supports run-time frequency tuning between 1–48 MHz in 1 MHz steps, with automatic calibration against the ECO or WCO reference.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. The CAPSENSE™ CSD block remains fully functional in Deep Sleep mode with 2.5 µA total system current. It supports low-power scan modes, automatic wake-up on touch event, and hardware-accelerated baseline tracking - all without CPU intervention.
Is external flash memory required for firmware updates?
No. The device includes 128 KB of on-chip flash with Read Accelerator and supports in-application programming (IAP). Secure bootloader implementations using the TRNG and hardware AES engine enable authenticated OTA updates without external memory.
