Product details
Overview
CY8C4148LDAS573XQLA1 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 for touch interfaces in harsh environments.
For engineers reviewing the CY8C4148LDAS573XQLA1 datasheet, CY8C4148LDAS573XQLA1 pinout, CY8C4148LDAS573XQLA1 application, or CY8C4148LDAS573XQLA1 equivalent, this device supports reconfigurable analog/digital blocks, Deep Sleep mode at 2.5 µA, hardware crypto acceleration (AES/SHA/TRNG), and five SCBs for flexible I²C/SPI/UART/LIN communication in safety-critical automotive ECUs.
Technical Context
The CY8C4148LDAS573XQLA1 implements a single-layer AHB-Lite interconnect between its Cortex-M0+ core, 384 KB flash with Read Accelerator, and peripherals including dual opamps with Deep Sleep operation, 12-bit 1-Msps SAR ADC with temperature sensor, and eight 16-bit TCPWM blocks supporting quadrature decoding and comparator-triggered kill signals.
Its programmable analog subsystem includes CTBm blocks configurable as opamps or comparators, while the digital layer integrates Smart I/O for Boolean logic on GPIOs and five Serial Communication Blocks (SCBs) that runtime-reconfigure among I²C, SPI, UART, or LIN Slave - all synchronized via a PLL-driven 48-MHz system clock derived from ECO or IMO sources.

FAQ
What is the maximum operating temperature grade for CY8C4148LDAS573XQLA1?
CY8C4148LDAS573XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per test condition HTOL and TC, and applies to the full 100-pin TQFP package with specified voltage and thermal derating limits.
Does CY8C4148LDAS573XQLA1 support CAN FD with ISO 11898-1:2015 compliance?
Yes - the integrated CAN FD block supports bit rates up to 5 Mbps, ISO 11898-1:2015 physical layer compliance, and protocol features including flexible data-rate switching, CRC-17/21, and error confinement. It operates independently of CPU load using dedicated DMA and message RAM buffers.
Can the SAR ADC perform simultaneous sampling across multiple channels?
No - the 12-bit SAR ADC uses a single conversion engine with channel sequencer and signal averaging, but does not support true simultaneous sampling. However, it achieves 1-Msps aggregate throughput with hardware-triggered sequencing and DMA-assisted result transfer to minimize CPU intervention.
Is ModusToolbox™ required to configure the programmable analog blocks?
ModusToolbox™ is the recommended and fully supported IDE for configuring CTBm opamps, MSC, TCPWM, and SCBs via graphical peripheral configurators and auto-generated PDL code. While register-level access is possible, production development relies on ModusToolbox™ for validated initialization sequences and SmartSense calibration workflows.
