Product details
Overview
CY8C4149LDE-S593 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on a 48-MHz Arm® Cortex®-M0+ CPU, featuring 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, 12-bit 1-Msps SAR ADC, and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.
For engineers reviewing the CY8C4149LDE-S593 datasheet, CY8C4149LDE-S593 pinout, CY8C4149LDE-S593 application, or CY8C4149LDE-S593 equivalent, this device supports reconfigurable analog/digital blocks, Deep Sleep mode at 2.5 µA, programmable SCBs for I²C/SPI/UART/LIN, TCPWM for motor control, and hardware crypto acceleration (AES/SHA/TRNG) - critical for automotive body electronics, infotainment HMI, and ADAS sensor interface design.
Technical Context
The CY8C4149LDE-S593 implements a tightly coupled system-on-chip architecture where the Cortex-M0+ core interfaces via single-layer AHB-Lite to programmable analog (CTBm opamps, SAR ADC, LP comparators), digital logic (Smart I/O, TCPWM), and fixed-function peripherals (CAN FD, I2S TX Master, MSC). Its clock system integrates ECO+PLL (48 MHz), WCO, IMO (±2%), and ILO for precise timing across sleep/wake transitions.
It supports concurrent operation of analog sensing (e.g., CAPSENSE™ in Deep Sleep), digital signal processing (via DMA-driven ADC sequencer with averaging), and real-time communication (CAN FD + dual SCBs in UART/I²C mode), enabling deterministic response in safety-critical automotive subsystems without external co-processors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic execution for ASIL-B–compatible firmware stacks. |
| Flash / SRAM | 384 KB flash with Read Accelerator; 32 KB SRAM - sufficient for AUTOSAR-compliant BSW + application layer with OTA update partitioning. |

IC Role / Device Role / Timing Role: Safety-monitoring MCU with temperature sensor, comparator-based overtemp shutdown, and CAN FD fault reporting. Use Value: Integrated temperature sensor (within SAR ADC) and LP comparators enable sub-100 ms thermal trip response without external thermistors or comparators. |
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; no integrated CAPSENSE™ or MSC block | Better suited for gateway/routing tasks; lacks native capacitive sensing hardware | Select when CAN FD + Ethernet coexistence is required, but add external touch controller for HMI. |
| Renesas RL78/F14 | 16-bit RL78 core @ 32 MHz; 256 KB flash; no CAN FD; only 10-bit ADC | Lower cost for basic body control; insufficient performance for complex CAPSENSE™ or crypto workloads | Choose for non-safety-critical interior switches where CAN FD and hardware crypto are not needed. |
Compared with S32K144W and RL78/F14, CY8C4149LDE-S593 uniquely integrates high-SNR capacitive sensing, Deep Sleep analog retention, and CAN FD in a single AEC-Q100 Grade-S package - making it optimal for automotive HMI and distributed sensor nodes where size, power, and mixed-signal integration are critical.

FAQ
What is the maximum operating temperature range for CY8C4149LDE-S593?
The CY8C4149LDE-S593 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per JEDEC JESD22-A104 and applies to all specified electrical parameters in the datasheet, including CAN FD timing, ADC accuracy, and Deep Sleep current consumption.
Does CY8C4149LDE-S593 support hardware-based secure boot?
Yes - the device includes a dedicated cryptography accelerator with AES-128/256, SHA-256, TRNG, and CRC engines, enabling hardware-verified secure boot through immutable ROM bootloader and encrypted flash image validation. Secure key storage uses eFuse-based provisioning, and all crypto operations execute in isolated hardware context.
Can the MSC block operate during Deep Sleep mode?
Yes - the Multi-Sense Converter (MSC) block remains fully functional in Deep Sleep mode with only 2.5 µA total system current. It supports autonomous capacitive scan, SmartSense auto-calibration, and interrupt generation upon touch detection - enabling zero-power wake-up for door handles or center console interfaces.
How many SCB blocks can be configured as I²C simultaneously?
All five Serial Communication Blocks (SCBs) can be independently configured as I²C masters or slaves at runtime. Each supports standard-mode (100 kbps), fast-mode (400 kbps), and fast-mode plus (1 Mbps), with hardware address matching and SMBus timeout detection - allowing concurrent communication with multiple sensors or displays without software arbitration.
