Product details
Overview
CY8C4148LDSS573XQLA1 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 automotive HMI systems requiring robust capacitive touch in harsh environments.
For engineers reviewing the CY8C4148LDSS573XQLA1 datasheet, CY8C4148LDSS573XQLA1 pinout, CY8C4148LDSS573XQLA1 application, or CY8C4148LDSS573XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), SAR ADC resolution (12-bit, 1 Msps), MSC SNR (>5:1), and GPIO reconfigurability across analog/digital/CAPSENSE™ functions.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5 reconfigurable Serial Communication Blocks (SCBs), and dedicated CAN FD controller with protocol acceleration and bit-rate switching support. Its analog subsystem includes two CTBm opamps with Deep Sleep operation, a 12-bit SAR ADC with temperature sensor and channel sequencer, and dual low-power comparators-all accessible via any of up to 84 GPIOs.
Digital flexibility is enabled by eight 16-bit TCPWM blocks supporting quadrature decoding and kill-signal triggering, programmable Smart I/O for Boolean logic on port signals, and hardware cryptography accelerators (AES, SHA, TRNG, CRC). Clocking combines ECO+PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO (40 kHz) sources with dynamic power mode coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - deterministic real-time execution with NVIC and MPU for automotive ASIL-B capable partitioning. |
| Memory | 384 KB flash with Read Accelerator + 32 KB SRAM - enables complex firmware with fast ISR response and data buffering for CAN FD message queues. |
| CAN FD | Up to 5 Mbps data rate with protocol offload - reduces CPU load during high-bandwidth vehicle network communication and supports ISO 11898-1:2015 compliance. |

FAQ
Is CY8C4148LDSS573XQLA1 qualified for automotive use?
Yes. It is AEC-Q100 qualified for Grade-S (–40°C to +105°C), with full qualification test reports covering thermal cycling, humidity bias HAST, and package reliability. The device meets automotive requirements for solderability, electrostatic discharge (HBM ±2 kV), and latch-up immunity (±200 mA), and is supported by Infineon's automotive quality management system certified to IATF 16949.
Does this part support CAN FD with ISO 11898-1:2015 compliance?
Yes. The integrated CAN FD controller supports data rates up to 5 Mbps, bit-rate switching, and ISO 11898-1:2015 frame formatting including flexible data-length fields and CRC calculation. Hardware features include TX/RX FIFOs, error counters, and loopback self-test mode-enabling full protocol stack implementation without external transceiver dependency for node-level validation.
Can all 84 GPIOs be used simultaneously for CAPSENSE™ sensing?
No. While all GPIOs are CAPSENSE™-capable, the Multi-Sense Converter (MSC) block supports up to 64 sensing channels per device. Channel allocation is constrained by routing resources and mutual capacitance crosstalk; practical designs typically use 32–48 electrodes. Pin multiplexing is managed dynamically via the PDL configuration tool, and SmartSense automatically selects optimal scan parameters per electrode.
What debug interfaces are supported, and is SWD sufficient for production programming?
CY8C4148LDSS573XQLA1 supports ARM Serial Wire Debug (SWD) via SWDCLK/SWDIO pins and includes ROM-based bootloader accessible via UART or I²C. SWD is fully sufficient for production programming: it enables secure flash locking, checksum verification, and boundary-scan-compatible JTAG-style access through standard CMSIS-DAP or Segger J-Link tools-no additional debug hardware is required for mass programming or field firmware updates.
