Product details
Overview
CY8C4148AZSS575XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Max microcontroller based on Arm® Cortex®-M0+ CPU, featuring 48 MHz operation, 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, and integrated CAPSENSE™ with SmartSense auto-tuning for capacitive touch interfaces in harsh environments.
For engineers reviewing the CY8C4148AZSS575XQLA1 datasheet, CY8C4148AZSS575XQLA1 pinout, CY8C4148AZSS575XQLA1 application, or CY8C4148AZSS575XQLA1 equivalent, this device supports reconfigurable analog/digital blocks, five SCBs (I²C/SPI/UART/LIN), eight TCPWMs, hardware crypto (AES/SHA/TRNG), and LCD segment drive - critical for functional-safety-aware body control, infotainment HMI, and motor control edge nodes.
Technical Context
The CY8C4148AZSS575XQLA1 implements a single-layer AHB-Lite interconnect between its Cortex-M0+ core and peripherals including SAR ADC, CTBm opamps, LP comparators, MSC block, and CAN FD controller. Its clock system integrates ECO (4–33 MHz) with PLL for 48 MHz core clock, WCO (32 kHz), IMO (±2%), and ILO (40 kHz), enabling precise timing across sleep/wake transitions.
Digital reconfigurability is realized via Smart I/O blocks and programmable logic units that perform Boolean operations on GPIO signals without CPU intervention, while analog flexibility includes dual opamps supporting ADC input buffering and Deep Sleep operation, plus a 12-bit 1-Msps SAR ADC with temperature sensor and channel sequencer.
