Product details
Overview
CY8C4149AZA-S545 from Infineon is an AEC-Q100 Grade-A (–40°C to +85°C) automotive-qualified 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), 12-bit 1-Msps SAR ADC, dual opamps with Deep Sleep operation, and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.
For engineers reviewing the CY8C4149AZA-S545 datasheet, CY8C4149AZA-S545 pinout, CY8C4149AZA-S545 application, or CY8C4149AZA-S545 equivalent, key selection criteria include CAN FD timing compliance, CAPSENSE™ water-tolerance performance, low-power analog operation in Deep Sleep (2.5 µA system current), and reconfigurable SCB blocks supporting I²C/SPI/UART/LIN in automotive body control and infotainment subsystems.
Technical Context
The CY8C4149AZA-S545 implements a tightly coupled mixed-signal architecture where the Cortex-M0+ core interfaces via AHB-Lite with programmable analog (CTBm opamps, SAR ADC, LP comparators) and digital (TCPWM, Smart I/O, MSC) peripherals. Its clock system integrates ECO+PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO (40 kHz) for deterministic timing across sleep/wake transitions.
Hardware cryptography acceleration includes AES-128/256, SHA-1/256, TRNG, PRNG, and CRC engines accessible via PDL APIs. The CAN FD block supports ISO 11898-1:2015 with bit rates up to 5 Mbps and flexible data field lengths (up to 64 bytes), enabling high-bandwidth vehicle network communication without protocol translation.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144HAT0MLHT | ARM Cortex-M4F @ 112 MHz, 512 KB flash, no integrated CAPSENSE™, CAN FD up to 5 Mbps | Lacks hardware-accelerated capacitive sensing; requires external touch controller or software-based solution | Select when higher CPU performance and floating-point math are required, but touch interface is handled externally |
| Renesas RL78/F14 | 16-bit RL78 core @ 32 MHz, 256 KB flash, CAN 2.0B only (no FD), no hardware crypto | No CAN FD or cryptographic acceleration; limited analog integration (10-bit ADC, no opamps) | Choose for cost-sensitive legacy CAN networks where FD bandwidth and security are not required |

FAQ
Does CY8C4149AZA-S545 support CAN FD conformance testing per ISO 16845?
Yes. The CAN FD block complies with ISO 16845:2017 conformance test requirements, including bit timing, error frame generation, and arbitration field handling. Test reports and validation documentation are available through Infineon's Automotive Support Portal upon NDA registration.
What is the maximum operating frequency of the SAR ADC when oversampling is enabled?
With 4× hardware oversampling and signal averaging, the effective resolution increases to 13 bits at 250 ksps. The base SAR ADC maintains 1 Msps throughput in non-averaged mode, and the sequencer supports automatic channel switching with ≤1 µs inter-channel delay.
Can the CTBm opamps drive external loads directly in Deep Sleep mode?
Yes. Each CTBm opamp supports rail-to-rail output swing and 20 mA continuous drive capability while operating in Deep Sleep mode. Output is configurable for unity-gain buffer, inverting/non-inverting amplifier, or comparator - all with sub-µA quiescent current per channel.
Is ModusToolbox™ required for firmware development, or can Keil MDK be used?
ModusToolbox™ is recommended but not mandatory. Keil MDK-ARM v5.36+ fully supports CY8C4149AZA-S545 via CMSIS-Pack and PDL v3.x. Debugging requires SWD interface; J-Link and ST-Link V3 are validated, with full trace and RTOS-aware debugging capabilities.
