Product details
Overview
CY8C4147AXI-S443 from Infineon Technologies (acquired Cypress Semiconductor) is a PSoC 4100S Plus programmable system-on-chip featuring a 48-MHz Arm Cortex-M0+ CPU, 128 KB flash, 16 KB SRAM, integrated CapSense® capacitive sensing, CAN 2.0B interface, and programmable analog/digital blocks. It targets embedded human-interface and industrial control applications requiring low-power operation (2.5 µA Deep Sleep), robust touch sensing in wet environments, and deterministic real-time communication.
For engineers reviewing the CY8C4147AXI-S443 datasheet, CY8C4147AXI-S443 pinout, CY8C4147AXI-S443 application, or CY8C4147AXI-S443 equivalent, key selection criteria include its 54 GPIO count with CapSense/ADC/analog/digital reconfigurability, 12-bit 1-Msps SAR ADC with sequencer, CAN 2.0B block with TTCAN support, and Deep Sleep–capable opamps and comparators.
Technical Context
The device integrates a single-core Arm Cortex-M0+ with tightly coupled flash accelerator and 8-channel DMA, enabling deterministic real-time firmware execution while minimizing power. Its analog subsystem includes two operational amplifiers (operational in Deep Sleep), a 12-bit SAR ADC with differential input and hardware averaging, and a dedicated capacitance-sensing block supporting Sigma-Delta (CSD) with >5:1 SNR.
Digital resources comprise five reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART, eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals, and a CAN 2.0B controller with Time-Triggered CAN (TTCAN) capability - all routed via a high-speed interconnect matrix and controllable through PSoC Creator's schematic-based design flow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, 48 MHz max - delivers deterministic real-time control with single-cycle multiply for motor timing and sensor fusion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S445 | Same die, 64-pin TQFP package with 54 GPIOs and identical peripherals - differs only in pin count and thermal characteristics. | Requires larger PCB footprint and different layout routing; better thermal dissipation for sustained 48-MHz operation. | Select when board space permits and higher thermal margin is required for continuous motor control or CAN traffic. |
| STM32G474RET6 | Arm Cortex-M4F @ 170 MHz, no integrated CapSense, includes FPU and advanced timers - lacks hardware sigma-delta touch engine and TTCAN. | Requires external touch controller or software-based capacitive sensing; uses standard CAN without time-triggered scheduling. | Select when floating-point math or higher CPU throughput is critical, and touch functionality can be implemented externally or via algorithmic methods. |
Compared with CY8C4147AZI-S445 and STM32G474RET6, CY8C4147AXI-S443 uniquely combines CapSense hardware acceleration, TTCAN, and Deep Sleep–capable analog blocks in a compact 44-pin package - making it optimal for cost-sensitive, space-constrained HMI and industrial control nodes where integrated touch and deterministic communication are mandatory.

FAQ
Does CY8C4147AXI-S443 support USB connectivity?
No. The device does not include a USB PHY or USB controller. It features five reconfigurable SCBs supporting I²C, SPI, and UART only. For USB host or device functionality, an external USB-to-UART bridge IC or companion chip is required. PSoC Creator does not provide native USB component support for this device family.
What development tools are required to program CY8C4147AXI-S443?
PSoC Creator IDE (v4.4 or later) is mandatory for schematic-based hardware configuration and component integration. Programming and debugging require a MiniProg3 or KitProg2/3 programmer/debugger connected via SWD. Arm GCC toolchain is embedded in PSoC Creator; no third-party compiler license is needed for basic firmware development.
Can the 12-bit SAR ADC perform simultaneous sampling on multiple channels?
No. The SAR ADC has a single conversion core with a multiplexer-based input stage. It supports hardware-sequenced conversions across up to 16 channels using the channel sequencer, but not true simultaneous sampling. For synchronized acquisition, external analog multiplexing or parallel ADCs are required.
Is the CAN block compatible with ISO 11898-1 physical layer standards?
The CAN controller implements ISO 11898-1 protocol logic only. It requires an external CAN transceiver (e.g., TJA1042, SN65HVD230) to interface with the physical bus. The device provides CAN_TX and CAN_RX signals compliant with the standard logic-level interface expected by industry transceivers.
