Cypress Semiconductcors' PSoC 4 BLE simplifies design of sensor-based systems and wearables, human interface devices, remote controls and toys

Cypress has introduced two highly integrated, single-chip Bluetooth Low Energy products that it says will simplify design of low-power, connected, sensor-based systems. The PSoC 4 BLE Programmable System-on-Chip delivers is a customisable solution for IoT applications, home automation, healthcare equipment, sports and fitness monitors, and other wearable smart devices; the PRoC BLE Programmable Radio-on-Chip provides a turnkey solution for wireless Human Interface Devices (HIDs), remote controls and applications requiring pure play wireless connectivity.

These Bluetooth Low Energy products enable complete systems by integrating a Bluetooth Smart radio, a 32-bit ARM Cortex-M0 core with ultra-low-power modes, programmable analogue blocks, and Cypress's CapSense capacitive touch-sensing. This combination of technology claims prolonged battery life, customisable sensing capabilities, and intuitive user interfaces.

Designers looking to create Bluetooth Smart products currently must, Cypress asserts, use software tools from multiple vendors and develop complex firmware to meet wireless specifications. Cypress has simplified the Bluetooth Low Energy protocol stack and profile configuration into a royalty-free, GUI-based BLE Component—a free embedded IC within PSoC represented by an icon—that can be dragged and dropped into designs using Cypress’s PSoC Creator integrated design environment (IDE). PSoC Creator enables complete system design in a single tool. Alternatively, users of Eclipse and other ARM-based tools can customise their own Bluetooth Low Energy solutions on PSoC Creator and export the design to their preferred IDE.

PSoC 4 BLE adds a Bluetooth Smart radio to the flexible PSoC 4 architecture and its integrated programmable analogue front-end for sensor interfaces and programmable digital peripherals for glue logic and control. This combination delivers a one-chip solution for Internet of Things applications. Both PSoC 4 BLE and PRoC BLE have an on-chip balun that simplifies antenna design while reducing board size and system cost.

The Cypress Bluetooth Low Energy solutions also contain programmable CapSense touch-sensing interfaces with built-in two-finger gestures using Cypress’s SmartSense Auto-tuning algorithm, which completely eliminates the requirement for manual system tuning; www.cypress.com/go/capsense
