PSOC™ 4000

Overview

The PSOC™ 4000 is a cost-effective, entry-level system-on-chip (SoC) that is based on a 32-bit Arm® processor. This SoC is designed to enable quick and simple upgrades of legacy 8-bit and 16-bit microcontrollers (MCUs).

One of the key features of the PSOC™ 4000 family is the integration of CAPSENSE™, an industry-leading capacitive sensing technology. This technology allows for advanced touch sensing capabilities, making it suitable for a wide range of applications.

In addition to CAPSENSE™, the PSOC™ 4000 family also features a range of programmable digital and analog peripherals. These peripherals include timers, counters, pulse-width modulators (PWMs), inter-integrated circuit (I2C) interfaces. The programmability of these peripherals allows designers to customize the SoC to suit their specific application requirements.

The PSOC™ 4000 family is suitable for a variety of consumer and industrial applications, thanks to its flexibility and range of features. Some possible applications include IoT devices, wearables, and industrial control systems.
