Product details
Overview
CY8C4148LDAS563XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on the 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. It targets body control modules, smart sensors, and infotainment interface controllers requiring robust capacitive touch in harsh environments.
For engineers reviewing the CY8C4148LDAS563XQLA1 datasheet, CY8C4148LDAS563XQLA1 pinout, CY8C4148LDAS563XQLA1 application, or CY8C4148LDAS563XQLA1 equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for automotive embedded design.
Technical Context
The device integrates a dual-domain clock system with ECO (4–33 MHz), PLL (generating 48 MHz), WCO (32 kHz), and low-power ILO (40 kHz), enabling precise timing across sleep/wake transitions. Its programmable analog subsystem includes two CTBm opamps supporting high-drive external mode and ADC input buffering, plus a 12-bit 1-Msps SAR ADC with built-in temperature sensor and channel sequencer.
Digital flexibility is delivered via five reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART/LIN Slave, eight TCPWM blocks with quadrature decode and comparator-triggered kill signals, and a dedicated CAN FD controller compliant with ISO 11898-1:2015 supporting data rates up to 5 Mbps.
