Product details
Overview
CY8C4146AZE-S245 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 control modules, smart door handles, and HVAC touch interfaces.
For engineers reviewing the CY8C4146AZE-S245 datasheet, CY8C4146AZE-S245 pinout, CY8C4146AZE-S245 application, or CY8C4146AZE-S245 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ with SmartSense auto-tuning, CAN 2.0B + TTCAN timing compliance, Deep Sleep current of 2.5 µA, and GPIO flexibility across 54 pins with programmable drive strength and slew rate.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (two opamps, 12-bit SAR ADC, two IDACs, two low-power comparators) and digital resources (Smart I/O, TCPWM, SCBs) operate concurrently under hardware routing control. All analog peripherals remain functional in Deep Sleep mode at 2.5 µA system current.
Its clock system integrates a 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO - with a PLL generating the precise 48-MHz CPU clock. The CAN block supports time-triggered operation with deterministic latency and synchronized sampling for safety-critical actuator control loops.

FAQ
What is the maximum operating temperature grade for CY8C4146AZE-S245?
CY8C4146AZE-S245 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C. This rating is validated across all silicon, package, and integrated peripherals including CAPSENSE™, CAN, and TCPWM blocks - confirmed in Infineon's official qualification report 002-20072 Rev. *S.
Does CY8C4146AZE-S245 support CAN FD or only classical CAN?
CY8C4146AZE-S245 implements a CAN 2.0B controller with Time-Triggered CAN (TTCAN) support but does not support CAN FD. Its bit rate is configurable up to 1 Mbps, and TTCAN features include time-synchronized message transmission, guaranteed latency, and deterministic scheduling - as defined in ISO 11898-4.
Can the on-chip CAPSENSE™ subsystem operate during Deep Sleep mode?
Yes - CAPSENSE™ CSD sensing remains fully operational in Deep Sleep mode with 2.5 µA total system current. The hardware sequencer autonomously scans electrodes, applies SmartSense tuning, and triggers wake-up interrupts without CPU involvement, enabling always-on touch detection in vehicle off-state.
Is ModusToolbox™ required to develop firmware for this device?
No - both ModusToolbox™ and the legacy PSoC™ Creator IDE support CY8C4146AZE-S245. PSoC™ Creator (Windows-only) offers schematic-based design and automatic analog/digital routing; ModusToolbox™ (cross-platform) provides CLI tools, Eclipse IDE, and GitHub-hosted PDL libraries - choice depends on workflow preference and OS environment.
