Overview

The CY8C4548AZI-S485 is a 32-bit ARM Cortex-M0+ microcontroller from the PSoC 4500S series, operating at 48MHz with 256KB of Flash and 32KB of SRAM. This versatile SoC integrates programmable analog blocks including op-amps, comparators, and a 12-bit ADC alongside Infineon signature CapSense technology for advanced touch sensing. It is designed to bridge the gap between traditional MCUs and mixed-signal SoCs by offering high-density memory and integrated motor control accelerators.

Why Choose This Part

The PSoC architecture provides significant flexibility through its programmable analog and digital blocks, allowing engineers to replace multiple external discrete components like op-amps and DACs. With a wide operating voltage range from 1.71V to 5.5V and 5V-tolerant I/O, it simplifies power supply design and legacy system integration.

Applications

Industrial Touch Interfaces
Utilizes CapSense technology for robust, noise-immune liquid-tolerant touch buttons and sliders.
Brushless DC (BLDC) Motor Control
Leverages the integrated motor control accelerator and PWM channels for efficient motor commutation.
Sensor Hubs
Aggregates data from multiple analog and digital sensors using the 16-channel ADC and 5 serial communication blocks.
Home Appliance Controllers
Combines LCD drive capability and internal analog front-ends to reduce external component count in white goods.
