Product details
Overview
CY8C4148AZES588XQLA1 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), and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.
For engineers reviewing the CY8C4148AZES588XQLA1 datasheet, CY8C4148AZES588XQLA1 pinout, CY8C4148AZES588XQLA1 application, or CY8C4148AZES588XQLA1 equivalent, key selection considerations include CAN FD timing compliance, Deep Sleep current (2.5 µA), programmable analog routing, MSC water-tolerance capability, and ModusToolbox™ API support for rapid CAPSENSE™ tuning.
Technical Context
The device implements a dual-clock domain architecture: a high-speed 48-MHz domain driven by PLL+ECO/WCO, and a low-power domain anchored by ILO/IMO for Deep Sleep operation. Its analog subsystem integrates two CTBm opamps (with ADC input buffering and Deep Sleep operation), a 12-bit 1-Msps SAR ADC with temperature sensor, and two low-power comparators - all accessible via any GPIO.
Digital flexibility is enabled by five reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART/LIN, eight TCPWM blocks with quadrature decode and comparator-triggered kill signals, and a dedicated CAN FD controller compliant with ISO 11898-1:2015 up to 5 Mbps, including bit-rate switching and flexible data-length support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic control with Thumb-2 instruction set and NVIC interrupt handling. |
| Flash / SRAM | 384 KB flash with Read Accelerator; 32 KB SRAM - supports complex automotive firmware with fast code execution and buffer-intensive sensor processing. |
| CAN FD Speed | Up to 5 Mbps with bit-rate switching - meets modern automotive ECU communication requirements for high-bandwidth diagnostics and OTA updates. |
| ADC Performance | 12-bit SAR, 1 Msps, differential/single-ended, channel sequencer with signal averaging - delivers precise battery voltage, temperature, and position sensing in noisy environments. |
| Deep Sleep Current | 2.5 µA digital system current with operational analog - enables always-on capacitive wake-up and low-power monitoring without external supervisors. |

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; includes FlexCAN FD, but lacks integrated CAPSENSE™ and programmable analog blocks. | Better floating-point math for motor control algorithms; requires external touch controller for capacitive UI. | Select when high-performance control loop execution dominates over touch integration cost and BOM simplicity. |
| Renesas RH850/F1L | 32-bit RXv2 core @ 120 MHz; ASIL-D capable, but no on-die capacitive sensing or reconfigurable analog/digital fabric. | Targeted at safety-critical powertrain applications; not optimized for human-machine interface subsystems. | Select only when ISO 26262 ASIL-D certification is mandatory and touch interface is handled externally. |
Compared with S32K144HAT0MLHT and RH850/F1L, CY8C4148AZES588XQLA1 uniquely integrates CAPSENSE™, programmable analog, and CAN FD in a single AEC-Q100 Grade-S package - reducing component count, board space, and firmware complexity for HMI-focused automotive ECUs.

FAQ
What is the maximum operating temperature range for CY8C4148AZES588XQLA1?
This part is AEC-Q100 Grade-S qualified, rated for continuous operation from –40°C to +105°C ambient temperature. It meets automotive thermal cycling requirements per JESD22-A104 and is validated for use in engine bay-adjacent modules and interior control units subject to solar loading.
Does CY8C4148AZES588XQLA1 support CAN FD bit-rate switching?
Yes, the integrated CAN FD controller supports bit-rate switching per ISO 11898-1:2015. The nominal arbitration phase runs up to 1 Mbps, while the data phase scales to 5 Mbps, with programmable timing registers and automatic resynchronization for robust error handling in electric vehicle networks.
Can the SAR ADC measure temperature directly without external components?
Yes, the 12-bit SAR ADC includes a factory-calibrated on-die temperature sensor. When configured in "Temperature Sensor" mode, it delivers ±2.5°C accuracy from –40°C to +105°C without external thermistors or signal conditioning circuitry.
Is ModusToolbox™ required to configure CAPSENSE™ functionality?
No, but ModusToolbox™ is strongly recommended. It provides the CAPSENSE™ Tuner GUI, SmartSense auto-tuning algorithm, and production-ready Component APIs. Raw register-level configuration is possible via PDL headers, but increases development time and risk of suboptimal SNR performance.
