Cypress – PSoC MCU dev kit features touch-sensing buttons and wireless connectivity


A new prototyping kit from Cypress enables customers to evaluate and develop projects using the PSoC 4000S, a family of programmable system-on-chip controller ICs.

PSoC 4000S devices feature an ARM® Cortex®-M0+ processor core, up to 32kbytes of Flash memory, 4kbytes of SRAM, up to 36 general purpose I/Os all capable of CapSense® capacitive sensing, as well as six programmable analogue blocks and seven programmable digital blocks. The PSoC CreatorTM Integrated Development Environment (IDE) enables rapid prototyping of end applications based on a PSoC 4000S device while minimising the requirement for PCB spins and firmware changes.

The PSoC MCU includes 16 Smart I/OsTM which provide pin-level Boolean operations on input and output signals, even when the device is in deep sleep. It also offers a programmable interconnect and routing sub-system which can be configured in the PSoC Creator IDE.

The introduction of the PSoC 4000S prototyping kit offers an open-footprint break- out board which enables the designer to take advantage of all the features of the PSoC 4000S.

The board includes the following features:
• Three CapSense buttons
• A five-segment CapSense slider
• LEDs to provide feedback
• Capacitors to support development of CapSense touch-sensing applications
• Bypass capacitor to ensure high-quality analogue-to-digital conversion
• A push-button to provide a simple user input
• Load capacitors to connect the 32kHz external crystal oscillator
• A Cypress EZ-BLE® PRoCTM radio module for Bluetooth® Low Energy connectivity

The PSoC 4000S prototyping kit also integrates the Cypress KitProg2, which enables on-board programming, debugging and USB-to-UART and USB-to-I2C bridging. KitProg2 is used to programme and debug the target PSoC 4000S/EZ-BLE PRoC devices. The PSoC 4000S kit allows the user to snap away the KitProg2 board from the PSoC 4000S target board.
