Product details
Overview
CY8C4148LDS-S553 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 running at 48 MHz, featuring 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, and integrated CAPSENSE™ with SmartSense auto-tuning for capacitive touch in harsh environments.
For engineers reviewing the CY8C4148LDS-S553 datasheet, CY8C4148LDS-S553 pinout, CY8C4148LDS-S553 application, or CY8C4148LDS-S553 equivalent, this part supports reconfigurable analog/digital blocks, Deep Sleep mode with 2.5 µA system current, hardware crypto acceleration (AES/SHA/TRNG), and five runtime-reconfigurable SCBs for I²C/SPI/UART/LIN - critical for automotive body control, infotainment HMI, and motor drive safety monitoring.
Technical Context
The device integrates a dual-domain clock system with ECO (4–33 MHz), PLL (generating 48 MHz), WCO (32 kHz), IMO (±2%), and ILO (40 kHz), enabling precise timing across sleep/wake transitions and real-time control loops. Its programmable analog subsystem includes two opamps supporting high-drive external and high-bandwidth internal modes, plus a 12-bit 1-Msps SAR ADC with built-in temperature sensor and channel sequencer.
Digital flexibility is delivered via eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals, five SCBs supporting concurrent protocols, and a dedicated CAN FD controller compliant with ISO 11898-1:2015 up to 5 Mbps - all routed through a high-speed I/O matrix supporting any GPIO as analog/digital/CAPSENSE™ input.
