Product details

Overview

CY8C4148LDAS553XQLA1 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 for robust capacitive touch in harsh environments.

For engineers reviewing the CY8C4148LDAS553XQLA1 datasheet, CY8C4148LDAS553XQLA1 pinout, CY8C4148LDAS553XQLA1 application, or CY8C4148LDAS553XQLA1 equivalent, this device supports reconfigurable analog/digital blocks, deep-sleep operation at 2.5 µA, hardware cryptography (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 CY8C4148LDAS553XQLA1 implements a dual-domain clock architecture with independent IMO (±2%), ILO (40 kHz), WCO (32.768 kHz), and ECO (4–33 MHz) sources, plus PLL for deterministic 48-MHz core timing. Its programmable analog subsystem includes two CTBm opamps supporting ADC input buffering and comparator modes, each operational in Deep Sleep.

Digital flexibility is delivered via eight TCPWM blocks with quadrature decode and kill-input triggering, five SCBs supporting concurrent protocols, and a dedicated CAN FD controller compliant with ISO 11898-1:2015, enabling real-time vehicle network communication with data rates up to 5 Mbps and payload lengths up to 64 bytes.

Key Specifications

Key Features

Feature	Design Value
Reconfigurable Analog Blocks	Two CTBm opamps configurable as buffers, comparators, or transimpedance amps - eliminates external signal-conditioning components in sensor front-ends.
SmartSense Auto-Tuning	Hardware-accelerated CAPSENSE™ calibration adjusts baseline and sensitivity in real time - removes manual tuning effort across temperature/humidity variations.
Runtime-Reconfigurable SCBs	Five Serial Communication Blocks dynamically switch between I²C/SPI/UART/LIN - reduces BOM count and simplifies protocol migration during development.
Deep Sleep with Analog Active	2.5 µA system current while SAR ADC, comparators, and MSC remain functional - enables always-on touch wake-up or low-power environmental monitoring.
Hardware Crypto Engine	Dedicated AES/SHA/TRNG accelerators offload CPU during secure boot and OTA update verification - prevents timing-side-channel attacks and ensures deterministic latency.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP S32K144HAT0MLHT	ARM Cortex-M4F @ 112 MHz, 512 KB flash, CAN FD, but lacks integrated CAPSENSE™ and programmable analog blocks.	Requires external touch controller and signal-conditioning ICs for capacitive HMI or sensor front-ends.	Preferred when floating-point math or higher CPU throughput is needed, but adds BOM complexity for analog sensing.
Renesas RL78/F14	16-bit RL78 core @ 32 MHz, 256 KB flash, CAN 2.0B only, no CAN FD or hardware crypto acceleration.	Limited to legacy CAN networks; no built-in touch or security features - requires external components for modern HMI/security.	Suitable for cost-sensitive, non-FD automotive modules where upgrade path to CAN FD is not required.

Compared with S32K144HAT0MLHT and RL78/F14, CY8C4148LDAS553XQLA1 uniquely integrates reconfigurable analog, CAPSENSE™, and CAN FD in a single AEC-Q100 Grade-S package - reducing component count and validation effort for next-gen automotive HMI and domain controllers.

FAQ

What is the maximum operating temperature range for CY8C4148LDAS553XQLA1?

CY8C4148LDAS553XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C. This rating is verified per test condition HTOL (High Temperature Operating Life) and TC (Temperature Cycling), making it suitable for under-hood and cabin applications where thermal stress exceeds standard commercial-grade limits.

Does CY8C4148LDAS553XQLA1 support CAN FD with ISO 11898-1:2015 compliance?

Yes, the integrated CAN FD block supports data rates up to 5 Mbps and conforms to ISO 11898-1:2015, including flexible data-length coding, CRC polynomial selection, and bit-rate switching. It operates without external transceivers - only requiring connection to a standard ISO 11898-2 physical layer transceiver.

Can all GPIO pins be used for CAPSENSE™ sensing simultaneously?

Yes, any of the 84 programmable GPIO pins can be assigned to CAPSENSE™ functionality via the ModusToolbox™ configuration tool. The MSC block supports up to 64 simultaneous sensing channels with hardware-accelerated scanning, and SmartSense auto-calibration adapts to parasitic capacitance variations across all configured pins.

Is hardware cryptographic acceleration available in Deep Sleep mode?

No - the AES/SHA/TRNG crypto engine is disabled in Deep Sleep mode to maintain 2.5 µA system current. However, the TRNG can be seeded prior to entering Deep Sleep, and cryptographic operations resume immediately upon wake-up with full key retention in SRAM protected by MPU.
