Product details
Overview
CY8C4148AZAS588XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade 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), 12-bit 1-Msps SAR ADC, dual opamps with Deep Sleep operation, and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.
For engineers reviewing the CY8C4148AZAS588XQLA1 datasheet, CY8C4148AZAS588XQLA1 pinout, CY8C4148AZAS588XQLA1 application, or CY8C4148AZAS588XQLA1 equivalent, this device supports reconfigurable analog/digital peripherals, hardware crypto acceleration (AES/SHA/TRNG), I2S Master TX, and five runtime-reconfigurable SCBs for mixed-protocol communication in safety-critical automotive ECUs.
Technical Context
The CY8C4148AZAS588XQLA1 implements a single-layer AHB-Lite interconnect architecture with dedicated peripheral buses for analog (SAR ADC, CTBm, LPC), digital (TCPWM, SCB, Smart I/O), and system resources (clock, reset, power). Its programmable analog subsystem includes two continuous-time opamps supporting ADC input buffering and comparator modes, both operational in Deep Sleep at 2.5 µA system current.
Digital flexibility is enabled by eight 16-bit TCPWM blocks with quadrature decode and kill-signal triggering, five SCBs supporting concurrent I²C/SPI/UART/LIN, and a dedicated CAN FD controller compliant with ISO 11898-1:2015. The MSC block delivers hardware-accelerated capacitive sensing with SmartSense auto-tuning and water tolerance-critical for automotive interior HMI.

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 core @ 112 MHz; includes Ethernet MAC but lacks integrated MSC and LCD drive | Better for high-speed gateway functions; requires external touch controller and display driver | Select when CAN FD + Ethernet coexistence is needed and touch/display integration is handled externally |

Yes. The integrated CAN FD block supports data rates up to 5 Mbps, ISO 11898-1:2015 physical layer signaling, and flexible bit timing configuration. It includes built-in error counters, loopback mode for self-test, and message RAM with hardware FIFOs-enabling robust communication in automotive networks without external transceivers.
What is the maximum operating temperature grade for this part?
This device is AEC-Q100 Grade-S qualified, rated for continuous operation from –40°C to +105°C ambient temperature. It meets automotive thermal cycling and high-temperature storage requirements per JESD22-A108, and its internal temperature sensor is calibrated across this full range for accurate die temperature monitoring.
Can the MSC block perform mutual-capacitance sensing?
Yes. The Multi-Sense Converter (MSC) supports both self-capacitance and mutual-capacitance configurations via firmware-selectable scan modes. Mutual-capacitance scanning enables true multi-touch detection on projected-capacitive overlays, with hardware-accelerated baseline tracking and noise suppression optimized for automotive EMI environments.
