Product details
Overview
CY8C4148LDSS593XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on Arm® Cortex®-M0+ CPU, featuring 48 MHz operation, 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.
For engineers reviewing the CY8C4148LDSS593XQLA1 datasheet, CY8C4148LDSS593XQLA1 pinout, CY8C4148LDSS593XQLA1 application, or CY8C4148LDSS593XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), CAPSENSE™ water tolerance, and reconfigurable SCB blocks supporting I²C/SPI/UART/LIN in automotive body control modules.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5x Serial Communication Blocks (SCBs), and CAN FD controller with dedicated DMA channels. Its analog subsystem includes two opamps with Deep Sleep support, a 12-bit 1-Msps SAR ADC with temperature sensor, and dual low-power comparators - all accessible via any GPIO.
Digital flexibility is enabled by 8x TCPWM blocks (supporting quadrature decode, center-aligned PWM, and comparator-triggered kill signals), programmable Smart I/O logic, and hardware crypto accelerators (AES, SHA, TRNG, CRC) for secure boot and firmware authentication in safety-critical ECUs.
