Product details
Overview
CY8C4146LQE-S263T 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 touch-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 infotainment HMI interfaces.
For engineers reviewing the CY8C4146LQE-S263T datasheet, CY8C4146LQE-S263T pinout, CY8C4146LQE-S263T application, or CY8C4146LQE-S263T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-die CAPSENSE™ with SmartSense auto-tuning, CAN 2.0B + TTCAN timing compliance, Deep Sleep current of 2.5 µA, and 54 GPIOs 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 blocks (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 across multiple nodes-critical for distributed automotive control.
