Product details
Overview
CY8C4148AZS-S545 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, CAN FD up to 5 Mbps, and integrated CAPSENSE™ with SmartSense auto-tuning for capacitive touch interfaces in harsh environments.
For engineers reviewing the CY8C4148AZS-S545 datasheet, CY8C4148AZS-S545 pinout, CY8C4148AZS-S545 application, or CY8C4148AZS-S545 equivalent, this device supports reconfigurable analog/digital blocks, Deep Sleep mode with 2.5 µA system current, hardware cryptography (AES/SHA/TRNG), and five runtime-reconfigurable SCBs for I²C/SPI/UART/LIN - critical for functional-safety-aware automotive body control and HMI designs.
Technical Context
The CY8C4148AZS-S545 implements a tightly coupled subsystem architecture: the Cortex-M0+ core interfaces via single-layer AHB-Lite to flash (with Read Accelerator), SRAM, and ROM-based PDL boot code, while programmable analog blocks (CTBm opamps, SAR ADC, LP comparators) and digital logic (TCPWM, Smart I/O) are routed through a high-speed I/O matrix. Clocking includes ECO+PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO (40 kHz).
Its CAN FD block operates independently of SCBs, supporting ISO 11898-1:2015 compliant frames at up to 5 Mbps with dedicated message RAM and filtering. The MSC block delivers >5:1 SNR for CAPSENSE™ and tolerates water overlay - enabled by hardware-accelerated signal processing and automatic calibration without host CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - deterministic real-time execution with NVIC and MPU support for ASIL-B capable partitioning. |
| Memory | 384 KB flash (with Read Accelerator), 32 KB SRAM - sufficient for AUTOSAR-compliant BSW + application layer with OTA update space. |
| CAN FD | Up to 5 Mbps data rate, ISO 11898-1:2015 compliant - enables high-bandwidth diagnostics and domain controller communication. |
| Power Modes | Deep Sleep: 2.5 µA system current with opamps/ADC active - supports always-on capacitive wake-up in door handle or seat occupancy sensing. |
| CAPSENSE™ | Multi-Sense Converter (MSC) with >5:1 SNR and water tolerance - eliminates false triggers in wet/humid cabin environments without firmware compensation. |
| Cryptography | AES-128/256, SHA-256, TRNG, CRC accelerators - offloads secure boot, key derivation, and message authentication from main CPU. |
| GPIO | Up to 84 pins, all configurable as analog/digital/CAPSENSE™ - enables single-chip integration of touch, LED drive, LIN slave, and sensor interface in compact ECUs. |
Pinout & Package
Package: 64-pin TQFP (10 mm × 10 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO7 | I/O power supply domains | Independent 1.71–5.5 V rails per port group - allows mixed-voltage interfacing (e.g., 3.3 V MCU logic + 5 V analog sensors). |
| P0[0]–P7[7] | Programmable GPIOs | All pins support CAPSENSE™, analog input, digital logic, and LCD segment drive - no fixed-function pin constraints. |
| CAN_TX / CAN_RX | Dedicated CAN FD transceiver interface | Hardwired to CAN FD block - no software routing required; supports dominant/recessive bit timing compliance. |
| SCB0_SDA / SCB0_SCL | I²C interface for SCB0 | Configurable as I²C master/slave, SPI, UART, or LIN - runtime reconfigurable without reset. |
| XTAL_IN / XTAL_OUT | External crystal oscillator inputs | Supports 4–33 MHz ECO with internal PLL - enables precise clock generation for CAN FD bit timing and ADC sampling synchronization. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration adjusts baseline and thresholds in real time - eliminates manual tuning across temperature/humidity gradients. |
| Deep Sleep analog retention | Opamps, comparators, and SAR ADC remain operational at 2.5 µA - enables low-power wake-on-touch or wake-on-voltage-threshold detection. |
| Runtime-reconfigurable SCBs | Five independent Serial Communication Blocks dynamically switch between I²C/SPI/UART/LIN modes - reduces BOM count and PCB footprint in multi-protocol gateways. |
| TCPWM kill-input triggering | Hardware comparator outputs directly trigger TCPWM shutdown - meets functional safety requirements for motor control fault response < 1 µs. |
| Hardware crypto acceleration | Dedicated AES/SHA/TRNG engines reduce CPU load by >90% vs. software-only implementation - improves real-time scheduling predictability in safety-critical tasks. |

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; includes Ethernet MAC and CAN FD with larger message RAM; lacks integrated CAPSENSE™ | Targeted at gateway/routing ECUs requiring higher compute and network connectivity; not optimized for capacitive HMI | Select when CAN FD routing, OTA security, or Ethernet bridging is primary; add external touch controller for HMI |
| Renesas RL78/F14 | 16-bit RL78 core @ 32 MHz; lower power (1.2 µA Deep Sleep) but no CAN FD; limited analog resources (10-bit ADC) | Suitable for cost-sensitive, low-complexity body electronics (e.g., mirror control) without touch or high-speed comms | Select for non-CAN FD, non-touch applications where ultra-low static current and legacy toolchain support are priorities |
Compared with S32K144W and RL78/F14, CY8C4148AZS-S545 uniquely integrates CAPSENSE™, CAN FD, and hardware crypto in a single AEC-Q100 Grade-S package - reducing component count and validation effort for automotive HMI and domain-specific control units.

FAQ
What is the maximum operating temperature grade for CY8C4148AZS-S545?
CY8C4148AZS-S545 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per test condition 2.5.1 of AEC-Q100 Rev-H and applies to the full 64-pin TQFP package variant with specified voltage and thermal derating conditions.
Does CY8C4148AZS-S545 support CAN FD physical layer termination?
No - CY8C4148AZS-S545 provides only the CAN FD protocol controller and message RAM; external CAN transceiver (e.g., Infineon TLE9251VS) is required for physical layer signaling, bus arbitration, and differential voltage compliance per ISO 11898-2.
Can all GPIO pins be used simultaneously for CAPSENSE™ and analog ADC functions?
Yes - any GPIO pin can be configured for CAPSENSE™ sensing or SAR ADC input in the same design, but not concurrently on the same pin. The MSC block and SAR ADC share analog routing resources; simultaneous use requires time-multiplexed configuration via firmware-controlled port register updates.
Is ModusToolbox™ required to develop firmware for CY8C4148AZS-S545?
No - while ModusToolbox™ is Infineon's recommended IDE with pre-integrated PDL drivers and CAPSENSE™ Tuner, the device is fully compatible with Arm® GCC toolchains, Keil MDK, and IAR Embedded Workbench using standard CMSIS headers and scatter-loading files provided in the official PSoC™ Creator archive.
