Product details
Overview
CY8C4148LDAS593XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), and multi-sense capacitive sensing (MSC) with >5:1 SNR. It supports CAPSENSE™, LCD segment drive, five reconfigurable SCBs (I²C/SPI/UART/LIN), and hardware crypto accelerators (AES, SHA, TRNG).
For engineers reviewing the CY8C4148LDAS593XQLA1 datasheet, CY8C4148LDAS593XQLA1 pinout, CY8C4148LDAS593XQLA1 application, or CY8C4148LDAS593XQLA1 equivalent, this device is selected for automotive body control modules, infotainment touch interfaces, motor control safety monitoring, and secure gateway subsystems requiring mixed-signal programmability, functional safety readiness, and CAN FD connectivity.
Technical Context
The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 8x TCPWM blocks with comparator-triggered kill signals, and dual CTBm opamps operable in Deep Sleep mode. Its analog subsystem includes a 12-bit 1-Msps SAR ADC with temperature sensor, two low-power comparators, and MSC block supporting SmartSense auto-tuning.
Digital flexibility is enabled by five Serial Communication Blocks (SCBs) supporting runtime reconfiguration between I²C, SPI, UART, or LIN Slave modes, plus a dedicated CAN FD controller compliant with ISO 11898-1:2015 and capable of 5 Mbps data rate with FD frame support. Clocking includes ECO+PLL (48 MHz), WCO, IMO (±2%), and ILO (40 kHz).

FAQ
Is CY8C4148LDAS593XQLA1 pin-compatible with other PSoC™ 4100S Max variants?
Yes - it shares identical 100-pin TQFP mechanical and electrical pinout with CY8C4148LQAS593XQLA1 and CY8C4148LQAS592XQLA1. Differences are limited to flash size (384 KB vs. 256 KB), SRAM (32 KB vs. 16 KB), and temperature grade (Grade-S vs. Grade-A), all supported by the same pin mapping and peripheral routing.
Does this device support AUTOSAR Basic Software Modules?
Yes - Infineon provides AUTOSAR 4.3-compliant MCAL drivers for CAN FD, ADC, PWM, and GPIO through the PSoC™ 4100S Max MCAL package. These integrate with Vector DaVinci Developer and ETAS ISOLAR-AE, enabling ASW development on top of standardized BSW layers.
What debug interfaces are supported, and is JTAG available?
CY8C4148LDAS593XQLA1 supports ARM Serial Wire Debug (SWD) only - SWDCLK and SWDIO pins provide full programming, real-time tracing, and non-intrusive breakpoints. JTAG is not implemented; SWD delivers equivalent functionality with reduced pin count and better noise immunity in automotive environments.
Can the MSC block support mutual-capacitance touchscreens?
No - the MSC block is optimized for self-capacitance sensing (buttons, sliders, proximity) and supports up to 64 self-capacitive sensors. Mutual-capacitance (matrix touchscreen) requires external controllers or higher-tier PSoC™ devices like the PSoC™ 6 series with dedicated CapSense CSD hardware.
