PSOC™ 4000S

The PSOC™ 4000S series is a family of system-on-chip (SoC) devices that builds upon the features of the PSOC™ 4000 family. Like the PSOC™ 4000, the PSOC™ 4000S series is a cost-effective, entry-level SoC that is based on a 32-bit Arm® processor, designed to enable quick and simple upgrades of legacy 8-bit and 16-bit microcontrollers (MCUs).

One of the key features of the PSOC™ 4000S series is the integration of Infineon's fourth-generation 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™ 4000S series also features a range of programmable digital and analog peripherals, including timers, counters, pulse-width modulators (PWMs), inter-integrated circuit (I2C) interfaces, and comparators. The programmability of these peripherals allows designers to customize the SoC to suit their specific application requirements.

The PSOC™ 4000S series also introduces Smart I/Os, which enable pin-level digital logic implementation. This feature allows for greater flexibility and customization of the SoC's I/O capabilities.

At the heart of the PSOC™ 4000S series is a 32-bit Arm® Cortex®-M0+ processor, which provides high performance and low power consumption. In fact, the PSOC™ 4000S series reduces average power consumption by boosting performance, allowing the system to spend more time in sleep modes.

The processor is capable of processing instructions at more than 2x the rate of legacy 8-bit and 16-bit MCUs, making it an ideal choice for mixed-signal embedded applications.

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