PSoC™ 4 overview

PSoC™ 4 has tackled some of the complex portions of embedded system design making it easier for you to get your product to market. Functions such as analog sensor integration, capacitive touch, and wireless connectivity have been integrated and optimized in PSoC™ 4 to just work.

The PSoC™ 4 portfolio consists of several families of Arm® Cortex®-M0 and Cortex®-M0+ microcontrollers. Most devices in the portfolio include Infineon's CAPSENSE™ technology for capacitive-sensing applications. Other key features in the PSoC™ 4 portfolio include a customizable analog front end through programmable analog blocks as well as wired and wireless connectivity options such as USB, CAN, and Bluetooth® Low Energy. These unique features make PSoC™ 4 the industry's most flexible and scalable low-power mixed-signal architecture.

Achieve ultimate flexibility in your design with Infineon's software-defined peripherals embedded in the PSoC™ 4 architecture. Configure these peripherals using pre-built library functions or create your own using the programmable architecture inside of PSoC™ 4 devices.

General MCU

Design a simple yet scalable and reconfigurable embedded system using the input/out peripherals, volatile/non-volatile memory and various communication interfaces. These features can be used to perform simple specific tasks or design an end product such as home automation systems, industrial control systems, medical devices, etc.

Programmable analog blocks

Customize your analog front end to interface to any analog sensor through programmable analog blocks, which are composed of an assortment of opamps, comparators, ADCs, and DACs, enabling complex analog signal flows. PSoC™ 4 can also eliminate the need for external analog components saving you time and money.

Programmable digital blocks

Programmable digital blocks are composed of Universal Digital Blocks (UDBs), Serial Communication Blocks (SCBs), and Timer/Counter/Pulse Width Modulators (TCPWM). These blocks can be configured to set up custom digital interfaces, state machines, and custom logic functions.

Capacitive sensing

Infineon's CAPSENSE™ is the industry-leading capacitive-sensing solution for touch buttons and sliders, proximity sensing, and liquid-level sensing applications. CAPSENSE™ is a dedicated peripheral found across the entire PSoC™ 4 portfolio featuring state-of-the-art noise immunity and water rejection.

Inductive sensing

Design sleek interfaces with advanced inductive sensing technology for highly reliable human machine interfaces, fully waterproof interfaces and other new, innovative solutions.

Motor and power control

The efficient Arm® Cortex®-M0+ CPU together with hardware accelerators for divide and square-root computation, and high performance analog makes PSoC™ 4 an ideal solution for motor control and power management applications.

Wired and wireless connectivity

Wired connectivity interfaces, such as CAN and USB, are available in the PSoC™ 4 portfolio. For wireless connectivity, Bluetooth® low energy is also available. With an integrated balun for antenna matching, PSoC™ 4 Bluetooth® Low Energy simplifies RF board design and reduces PCB footprint. With example projects and development kits, as well as all Bluetooth® Low Energy profiles and APIs, you can get Bluetooth® Low Energy connectivity and running in a matter of minutes.
