Product details
Overview
CY8C4147AZI-S443 from Infineon Technologies (acquired Cypress Semiconductor) is a 32-bit Arm Cortex-M0+ programmable system-on-chip (PSoC 4100S Plus) integrating MCU, CapSense capacitive sensing, programmable analog/digital blocks, CAN 2.0B interface, and LCD drive capability. It delivers 48 MHz operation, 128 KB flash, 16 KB SRAM, 54 GPIOs, and Deep Sleep current as low as 2.5 µA - deployed in industrial HMI touch panels, smart sensor nodes, and motor control interfaces requiring integrated signal conditioning and secure firmware execution.
For engineers reviewing the CY8C4147AZI-S443 datasheet, CY8C4147AZI-S443 pinout, CY8C4147AZI-S443 application, or CY8C4147AZI-S443 equivalent, key selection criteria include its dual-mode CapSense sigma-delta engine (SNR >5:1), CAN 2.0B + TTCAN support, 12-bit SAR ADC with sequencer, TRNG for cryptographic key generation, and SWD debug security with configurable flash protection.
Technical Context
The device implements a tightly coupled Arm Cortex-M0+ core with single-cycle multiply, 8-channel DMA, NVIC with eight interrupts, and Wakeup Interrupt Controller (WIC) enabling sub-35 µs wake-from-Deep-Sleep latency. Its analog subsystem includes two opamps operable in Deep Sleep, a 12-bit 1-Msps SAR ADC with differential input and channel sequencing, and a dedicated capacitance-sensing block supporting CSD-based touch detection.
Digital resources comprise five reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART, eight 16-bit TCPWM blocks with center-aligned/PWM/quad-decoder modes, and a CAN 2.0B controller with Time-Triggered CAN (TTCAN) compliance. Clocking is managed via IMO (±2%), ILO (32 kHz), WCO, ECO (4–33 MHz), and PLL - all synchronized without glitching using 18 programmable dividers (6 fractional, 12 integer).

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4146AZI-S433 | Same PSoC 4100S Plus family; 64 KB flash, 8 KB SRAM, no CAN block - lacks TTCAN and reduced memory. | Suitable for cost-sensitive CapSense-only designs without CAN or large firmware footprint. | Select when CAN interface and >100 KB flash are unnecessary; lower unit cost but no automotive timing compliance. |
| STM32G071CBT6 | Arm Cortex-M0+, 128 KB flash, 36 KB SRAM, no integrated CapSense or programmable analog; requires external touch controller. | Better suited for general-purpose control with rich peripheral set (USB, advanced timers), but adds BOM complexity for touch systems. | Choose when USB connectivity or higher SRAM is prioritized over integrated analog/touch - increases design effort for CapSense implementation. |
Compared with CY8C4147AZI-S443, CY8C4146AZI-S433 offers lower cost but omits CAN and reduces memory, limiting automotive and industrial networked use; STM32G071CBT6 provides more SRAM and USB but requires external components for CapSense, increasing PCB area and validation effort.

FAQ
Does CY8C4147AZI-S443 support USB communication?
No. The CY8C4147AZI-S443 does not include a USB controller or PHY. Its serial communication peripherals are limited to five reconfigurable SCBs supporting I²C, SPI, and UART only. For USB connectivity, external bridge ICs (e.g., CP2102N) or migration to PSoC 4 BLE/4000S families with integrated USB are required.
What is the maximum operating temperature for this device?
The CY8C4147AZI-S443 is rated for industrial temperature range: –40 °C to +85 °C ambient. This specification is confirmed in the "Device Level Specifications" section (Page 15) of datasheet 002-19966 Rev. *H, and applies across all power modes and peripheral configurations.
Can the CapSense block operate independently of the CPU core?
Yes. The CapSense CSD block operates autonomously using dedicated hardware resources and can scan sensors while the CPU remains in Deep Sleep mode. Scan results are stored in dedicated registers or SRAM via DMA, enabling ultra-low-power touch wake-up without CPU intervention.
Is external flash memory required for firmware storage?
No. All firmware executes directly from the on-chip 128 KB flash memory, which includes a Read Accelerator delivering 85% of SRAM access speed. External flash is unnecessary unless application data logging exceeds available SRAM or requires non-volatile storage beyond flash endurance limits.
