Product details
Overview
CY8C4148AZES575XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Max microcontroller based on the Arm® Cortex®-M0+ CPU running at 48 MHz, featuring 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), and CAPSENSE™ multi-sense converter with >5:1 SNR for robust capacitive touch in harsh environments.
For engineers reviewing the CY8C4148AZES575XQLA1 datasheet, CY8C4148AZES575XQLA1 pinout, CY8C4148AZES575XQLA1 application, or CY8C4148AZES575XQLA1 equivalent, this device supports reconfigurable analog/digital blocks, Deep Sleep mode with 2.5 µA system current, hardware crypto acceleration (AES/SHA/TRNG), and five SCBs supporting I²C/SPI/UART/LIN - critical for automotive body control, infotainment HMI, and motor control edge nodes.
Technical Context
The CY8C4148AZES575XQLA1 integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 8 TCPWM blocks with quadrature decode and kill-signal triggering, and dual CTBm opamps operable in Deep Sleep. Its analog subsystem includes a 12-bit 1-Msps SAR ADC with temperature sensor, two low-power comparators, and MSC block enabling water-tolerant capacitive sensing via SmartSense auto-tuning.
Digital flexibility is delivered through five reconfigurable Serial Communication Blocks (SCBs), CAN FD controller with bit-rate switching up to 5 Mbps, I2S TX Master, and programmable Smart I/O logic. Clocking combines ECO (4–33 MHz) + PLL, WCO (32 kHz), IMO (±2%), and ILO (40 kHz) for deterministic timing across sleep/wake transitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F @ 112 MHz; 512 KB flash; no integrated CAPSENSE™; requires external touch controller | Better floating-point performance for motor control algorithms; lacks native capacitive sensing | Select when high-precision FOC motor control dominates over HMI touch integration |
| Renesas RL78/F14 | 16-bit RL78 core @ 32 MHz; 256 KB flash; CAN 2.0B only; no crypto accelerator or MSC block | Lower cost for legacy CAN networks; insufficient SNR and water tolerance for modern touch interfaces | Select for cost-sensitive, non-touch body modules where CAN FD and security are not required |

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4148AZES575XQLA1?
The Arm® Cortex®-M0+ core operates at a maximum frequency of 48 MHz, achieved via internal PLL locked to an external crystal oscillator (ECO) ranging from 4 to 33 MHz. This frequency is fully supported across the full Grade-S temperature range (–40°C to +105°C) and is verified per AEC-Q100 stress testing protocols.
Does CY8C4148AZES575XQLA1 support CAN FD with bit-rate switching?
Yes - the integrated CAN FD controller supports bit-rate switching, enabling arbitration phase at 1 Mbps and data phase up to 5 Mbps. It complies with ISO 11898-1:2015 and includes dedicated TX/RX pins, FIFO buffers, and error counters accessible via ModusToolbox™ PDL APIs.
How does the CAPSENSE™ MSC block achieve water tolerance?
The MSC block uses spread-spectrum modulation, adaptive baseline tracking, and hardware-accelerated signal averaging to maintain >5:1 SNR under condensation. SmartSense auto-tuning dynamically adjusts scan parameters without host CPU intervention, validated per ISO 16750-4 humidity cycling tests.
Is Deep Sleep mode functional with analog peripherals enabled?
Yes - Deep Sleep mode retains operation of both low-power comparators and the MSC block while drawing only 2.5 µA digital current. The SAR ADC and opamps can be woken on comparator trigger or timer event, enabling wake-on-touch with sub-10 µA total system current.
