Product details
Overview
CY8C4146AZE-S265T from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Plus microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive touch-sensing with SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (I²C/SPI/UART/LIN), a CAN 2.0B interface with TTCAN support, and eight 16-bit TCPWM units-used in motor control, automotive body electronics, and human-machine interface modules.
For engineers reviewing the CY8C4146AZE-S265T datasheet, CY8C4146AZE-S265T pinout, CY8C4146AZE-S265T application, or CY8C4146AZE-S265T equivalent, key selection criteria include its AEC-Q100 qualification, Deep Sleep current (2.5 µA), 54 GPIO count with full CAPSENSE™/analog/digital flexibility, and hardware-accelerated sigma-delta capacitive sensing with >5:1 SNR.
Technical Context
This device implements a tightly integrated mixed-signal SoC architecture where programmable analog blocks (two opamps, 12-bit SAR ADC, two IDACs, two low-power comparators) coexist with digital logic resources including Smart I/O for Boolean port-level operations and eight TCPWM blocks supporting quadrature decoding and comparator-triggered kill signals. Its clock system combines a 4–33 MHz ECO, PLL, 32-kHz WCO, and ±2% IMO for precise timing across operating modes.
The CAN block supports time-triggered CAN (TTCAN) for deterministic communication in safety-critical automotive subsystems, while the CAPSENSE™ CSD engine delivers water-tolerant touch performance without external components-enabled by dedicated hardware sigma-delta modulation and automatic SmartSense tuning.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZE-S475 | Same PSoC™ 4100S Plus family; 256 KB flash, 32 KB SRAM, identical peripheral set and package. | Higher memory capacity supports larger AUTOSAR-compliant stacks or OTA update partitions. | Select when firmware complexity exceeds 128 KB flash budget or dual-bank secure boot is required. |
| NXP S32K144HAT0MLHT | ARM Cortex-M4F core, 112 MHz, CAN FD, no integrated CAPSENSE™, requires external touch controller. | Targeted at higher-performance motor control or gateway applications needing CAN FD bandwidth and FPU acceleration. | Select when floating-point math, CAN FD, or ASIL-D decomposition is mandatory; not drop-in for CAPSENSE™-centric designs. |
Compared with CY8C4147AZE-S475, this part trades memory headroom for cost-sensitive volume production; versus S32K144HAT0MLHT, it offers superior integrated capacitive sensing but lacks CAN FD and floating-point capability-making it optimal for touch-centric AEC-Q100 Grade-S body electronics.

FAQ
Is CY8C4146AZE-S265T qualified for automotive use?
Yes. It is AEC-Q100 qualified for Grade-S operation (–40°C to +105°C), with full qualification documentation available from Infineon. The device undergoes stress testing for thermal cycling, humidity, and ESD per AEC standards, and is intended for non-safety-critical automotive applications including door modules and climate controls.
Does this part support CAN FD?
No. CY8C4146AZE-S265T integrates a CAN 2.0B controller with time-triggered CAN (TTCAN) support but does not implement CAN FD physical layer or protocol extensions. For CAN FD requirements, consider Infineon's AURIX™ family or NXP S32K series devices.
What development tools are supported?
Infineon officially supports ModusToolbox™ (Eclipse-based, cross-platform) and legacy PSoC™ Creator (Windows-only). Both provide CAPSENSE™ configuration tools, Peripheral Driver Library (PDL), and BSPs for kits like CY8CKIT-149. Debugging uses SWD interface compatible with standard Arm® debug probes.
Can all 54 GPIOs be used simultaneously for CAPSENSE™?
No. While all 54 pins are CAPSENSE™-capable, simultaneous use is constrained by shared analog routing resources and CTB (continuous-time block) limitations. Practical CAPSENSE™ channel count depends on sensor layout and resolution requirements-typically up to 32 self-capacitive or 16 mutual-capacitive sensors per device, as validated in AN85951.
