Product details
Overview
CY8C4148AZSS555XQLA1 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 CY8C4148AZSS555XQLA1 datasheet, CY8C4148AZSS555XQLA1 pinout, CY8C4148AZSS555XQLA1 application, or CY8C4148AZSS555XQLA1 equivalent, key selection considerations include its 84 GPIO count with full analog/digital/CAPSENSE™ reconfigurability, Deep Sleep current of 2.5 µA with active analog, and hardware crypto acceleration for AES/SHA/TRNG in safety-critical automotive firmware.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5 reconfigurable Serial Communication Blocks (SCBs), and 8 TCPWM blocks supporting quadrature decoding and comparator-triggered kill signals for motor control. Its analog subsystem includes two opamps with Deep Sleep operation, a 12-bit 1-Msps SAR ADC with temperature sensor, and dual low-power comparators.
The programmable architecture enables runtime peripheral reconfiguration: SCBs switch between I²C/SPI/UART/LIN Slave modes; GPIOs dynamically assign CAPSENSE™, analog input, or LCD segment drive functions; and Smart I/O logic performs Boolean operations directly on port signals without CPU intervention.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core @ 112 MHz; 512 KB flash; no integrated CAPSENSE™; requires external touch controller | Better floating-point performance for motor control algorithms; lacks native capacitive sensing capability | Select when prioritizing computational throughput over HMI integration density |

FAQ
What is the maximum operating temperature grade for CY8C4148AZSS555XQLA1?
This part is qualified to AEC-Q100 Grade-S, with guaranteed operation from –40°C to +105°C ambient temperature. It uses a 100-pin TQFP package with wettable flanks to ensure solder joint reliability during automotive thermal cycling tests per JESD22-A104.
Does CY8C4148AZSS555XQLA1 support CAN FD with ISO 11898-1:2015 compliance?
Yes. The integrated CAN FD block supports data rates up to 5 Mbps, bit-rate switching, and ISO 11898-1:2015 frame formatting. It includes built-in TX delay compensation, error counters, and loopback self-test mode for production validation.
Can all 84 GPIOs be used simultaneously for CAPSENSE™ sensing?
No. While any GPIO can be assigned to CAPSENSE™, the Multi-Sense Converter (MSC) block supports up to 64 simultaneous sensing channels. Concurrent use of analog ADC, opamps, or LCD drive reduces available CAPSENSE™ channels due to shared analog routing resources.
Is ModusToolbox™ required for firmware development?
No. ModusToolbox™ is Infineon's recommended IDE with PDL libraries and CAPSENSE™ Tuner, but the device supports standard Arm® GCC toolchains, Keil MDK, and IAR Embedded Workbench. All peripheral registers follow CMSIS-compliant memory maps for vendor-agnostic development.
