PSOC™ 4000S

Best-in-class capacitive sensing solution on a 32-bit MCU

anchor

Overview

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 MCU 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).

Key Features

  • 48 MHz Arm® Cortex®-M0+ CPU
  • Up to 32 KB flash, up to 4 KB SRAM
  • Best-in-class signal-to-noise ratio
  • Self-capacitive & mutual-capacitve
  • Automatic hardware tuning
  • Single-slope 10-bit ADC function
  • Two current DACs (IDACs)
  • Two low-power comparators
  • Run-time reconfigurable SCBs
  • Five 16-bit TCPWM blocks
  • Operating voltage: 1.71 V to 5.5 V
  • Up to 36 I/O with 16 Smart I/O

About the PSOC™ 4000

The key features of the PSOC™ 4000S series is the integration of Infineon's fourth-generation CAPSENSE™, an industry-leading capacitive sensing technology which allows for advanced touch sensing capabilities, making it suitable for a wide range of applications such as proximity switch, touch button, capacitive slider and capacitive trackpad with robust liquid tolerance. 

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 MCU to  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 MCU's I/O capabilities.

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, home appliances, and industrial control systems.

4th generation CAPSENSE™

PSOC™ 4000S CAPSENSE™ can be used to build a self or mututal capacitive sensing applciation. CAPSENSE™ is supported in the PSOC™ 4000S through a CAPSENSE™ Sigma-Delta (CSD) block that can be connected to any pins through an analog multiplex bus via analog switches. CAPSENSE™ function can thus be provided on any available pin or group of pins in a system under software control.
