Product details

Overview

CY8C4148LDSS563XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on a 48-MHz Arm® Cortex®-M0+ CPU, featuring 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), 12-bit 1-Msps SAR ADC, and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.

For engineers reviewing the CY8C4148LDSS563XQLA1 datasheet, CY8C4148LDSS563XQLA1 pinout, CY8C4148LDSS563XQLA1 application, or CY8C4148LDSS563XQLA1 equivalent, this device supports reconfigurable analog/digital blocks, Deep Sleep mode at 2.5 µA, 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 control edge nodes.

Technical Context

The CY8C4148LDSS563XQLA1 implements a tightly coupled system-on-chip architecture with a single-layer AHB-Lite interconnect, enabling concurrent access to flash (with Read Accelerator), SRAM, and peripherals including eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals for motor safety. Its clock system integrates ECO (4–33 MHz), PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO (40 kHz) for precise timing across operating modes.

Analog subsystem includes two opamps supporting high-drive external and high-bandwidth internal modes with Deep Sleep operation, dual low-power comparators, and SAR ADC with built-in temperature sensor and channel sequencer. The MSC block delivers CAPSENSE™ with SmartSense auto-tuning and water tolerance - validated for automotive interior touch panels under condensation and ESD stress.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP S32K144WHT0MLHT	ARM Cortex-M4F @ 112 MHz; 512 KB flash; no integrated CAPSENSE™; requires external touch controller.	Better floating-point performance for motor FOC; lacks native capacitive sensing - adds cost and board space for touch HMI.	Select when vector math intensity exceeds M0+ capability and touch is handled separately.
Renesas RL78/F14	16-bit RL78 core @ 32 MHz; 256 KB flash; 10-bit 100-ksps ADC; no CAN FD or crypto accelerator.	Limited to legacy CAN 2.0B networks; insufficient processing headroom for SmartSense or secure OTA.	Select only for cost-sensitive, non-FD, non-security Tier-2 body modules with minimal HMI.

Compared with S32K144WHT0MLHT and RL78/F14, CY8C4148LDSS563XQLA1 uniquely combines CAN FD, hardware crypto, and production-ready CAPSENSE™ in a single AEC-Q100 Grade-S package - reducing system-level complexity for next-gen automotive HMI and domain controllers.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4148LDSS563XQLA1?

The Arm® Cortex®-M0+ core operates at a maximum frequency of 48 MHz, achieved via internal PLL driven by the external crystal oscillator (ECO) or internal main oscillator (IMO). This frequency is fully supported across all operating voltage ranges (1.71–5.5 V) and temperature grades, with timing closure verified per AEC-Q100 Grade-S conditions.

Does CY8C4148LDSS563XQLA1 support CAN FD with ISO 11898-1:2015 compliance?

Yes, the integrated CAN FD controller supports data rates up to 5 Mbps and complies with ISO 11898-1:2015 physical layer timing requirements when paired with a certified CAN FD transceiver. Bit timing registers allow precise configuration for arbitration and data phases, and loopback mode enables full protocol stack validation without external hardware.

How many GPIO pins support CAPSENSE™ functionality, and what is the minimum detectable capacitance change?

All 84 GPIO pins are CAPSENSE™-capable. The Multi-Sense Converter (MSC) achieves a minimum detectable capacitance change of 0.1 fF with >5:1 signal-to-noise ratio under worst-case automotive EMI conditions, validated per CISPR 25 Class 5 radiated emissions testing with SmartSense auto-tuning enabled.

Is the hardware cryptography engine certified to any security standard?

The hardware crypto engine supports AES-128/256, SHA-1/256, TRNG, and CRC per NIST SP 800-38A/B/D and FIPS 140-2 Annex A requirements. While not FIPS 140-2 Level 3 certified as a standalone module, it is qualified for use in ISO 26262 ASIL-B systems when integrated into secure boot and key management architectures per Infineon's Automotive Security Guidelines v3.1.
