Overview

The CY8C4547AZI-S475 is a 48MHz Arm Cortex-M0+ microcontroller from the PSoC 4500S series featuring 128KB Flash and 32KB SRAM. It integrates advanced programmable analog and digital peripherals, including a high-performance CapSense capacitive sensing block and reconfigurable opamps.

Why Choose This Part

This PSoC 4 variant stands out with its rich analog integration, featuring four reconfigurable opamps and two IDACs alongside a 12-bit SAR ADC. The hardware-based math accelerators and 8-channel DMA engine provide computational performance beyond typical Cortex-M0+ implementations.

Applications

Capacitive Touch Interfaces
Utilizes the integrated CapSense sigma-delta (CSD) block for high-SNR buttons, sliders, and proximity sensing in consumer or industrial panels.
Precision Analog Sensing
Leverages the 12-bit SAR ADC with channel sequencer and internal opamps for processing sensor signals without external active circuitry.
Industrial Control
The 8-channel DMA and hardware math accelerators for divide and square root operations offload the CPU for real-time control loops.
Low-Power Handheld Devices
Optimized for battery operation with a 2.5uA standby current and the ability for opamps and comparators to remain active in Deep Sleep mode.
