Product details
Overview
CY8C4148AZSS585XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on Arm® Cortex®-M0+ CPU running at 48 MHz, featuring 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, 12-bit 1-Msps SAR ADC, and integrated CAPSENSE™ with SmartSense auto-tuning. It targets body control modules and in-vehicle human-machine interface systems requiring robust capacitive touch and real-time motor control.
For engineers reviewing the CY8C4148AZSS585XQLA1 datasheet, CY8C4148AZSS585XQLA1 pinout, CY8C4148AZSS585XQLA1 application, or CY8C4148AZSS585XQLA1 equivalent, this page delivers verified technical context, package mapping to 100-pin TQFP, validated pin functions, real-world use-value metrics for CAN FD timing, ADC SNR, and Deep Sleep current, and two confirmed drop-in alternatives with documented functional trade-offs.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5 reconfigurable Serial Communication Blocks (SCBs), and a dedicated CAN FD controller supporting ISO 11898-1:2015 with bit rates up to 5 Mbps and payload lengths up to 64 bytes. Its analog subsystem includes two CTBm opamps with Deep Sleep operation and a 12-bit SAR ADC with differential input, channel sequencer, and hardware signal averaging.
Programmable digital resources include eight TCPWM blocks supporting center-aligned PWM, quadrature decoding, and comparator-triggered kill signals for motor safety; plus Smart I/O logic enabling Boolean operations directly on GPIOs without CPU intervention. The MSC block delivers >5:1 SNR for CAPSENSE™ and supports water-tolerant touch sensing via hardware-accelerated SmartSense tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+ @ 48 MHz - deterministic real-time execution with 32-bit integer performance suitable for motor control loops and LIN/CAN protocol stacks. |
| Memory | 384 KB flash with Read Accelerator + 32 KB SRAM - enables dual-bank firmware updates and real-time data buffering for sensor fusion applications. |
| CAN FD | Up to 5 Mbps data rate, 64-byte payloads - supports high-bandwidth vehicle diagnostics and ECU-to-ECU firmware updates over CAN physical layer. |
| ADC | 12-bit SAR, 1 Msps, differential mode, hardware averaging - achieves ±1 LSB INL for precision battery voltage monitoring and temperature sensing. |
| Power Modes | Deep Sleep: 2.5 µA digital + operational analog - sustains CAPSENSE™ wake-on-touch and comparator monitoring while preserving system state. |
| GPIO | Up to 84 pins, all configurable as CAPSENSE™/analog/digital, programmable drive strength/slew rate - eliminates external level shifters in mixed-voltage automotive domains (1.8 V–5.5 V). |
| Clock Sources | ECO (4–33 MHz) + PLL + WCO (32 kHz) + IMO (±2%) + ILO (40 kHz) - enables precise timekeeping, low-jitter PWM generation, and fail-safe clock redundancy. |

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, 512 KB flash, no integrated CAPSENSE™, requires external touch controller | Better floating-point performance for motor FOC; lacks hardware touch tuning and Smart I/O logic | Select when advanced motor control algorithms dominate over HMI features |
| Renesas RA6M5GFP002FBC0 | ARM Cortex-M33 @ 200 MHz, 2 MB flash, TrustZone security, no CAN FD - only standard CAN 2.0B | Stronger security and memory for OTA updates; limited to 1 Mbps CAN and no hardware CAPSENSE™ acceleration | Select when secure boot and encrypted firmware delivery are mandatory, and CAN FD is not required |
