Cypress Semiconductor Corp. has unleashed what it describes as a highly integrated, single-chip Bluetooth Low Energy solutions available in additional packaging and temperature range options. The PSoC 4 BLE Programmable SoC and PRoC BLE Programmable Radio-on-Chip solutions each now have an option for a micro-ball CSP optimised to bring Bluetooth Smart connectivity to secure credit card applications. The package is only 0.38mm thick, making the reliable and fully Bluetooth-certified solutions ideal to replace chip-on-board devices.

Cypress also offers solutions with an extended industrial temperature range option with operation from -40C to 105C. This ensures consistent product performance throughout this temperature range for industrial, automotive and lighting applications that must operate in extreme climates. Both the micro-ball CSP package and extended industrial temperature options will be available for the 128KB and 256KB flash versions of the PSoC 4 BLE and PRoC BLE solutions. The offerings are pin-to-pin compatible with Cypress' original Bluetooth Low Energy solutions, simplifying upgrades, said the company.

Cypress's customisable Bluetooth Low Energy solutions promise unprecedented ease-of-use and integration for IoT applications, home automation, wireless human interface devices (HIDs), remote controls, healthcare equipment, sports and fitness monitors, and other wearable smart devices. PRoC BLE is a Bluetooth Smart MCU with Cypress' CapSense capacitive touch-sensing functionality, while PSoC 4 BLE offers expanded design versatility by adding intelligent analogue and programmable digital blocks. Both solutions integrate a Bluetooth Smart radio, a high-performance 32bit ARM Cortex-M0 core with ultra-low-power modes, up to 256KB flash memory, 36 GPIOs and customisable serial communication blocks, timers and counters. Additionally, both solutions have an on-chip balun that simplifies antenna design while reducing board size and system cost.

Additionally, Cypress offers the small-form-factor, Bluetooth Smart, EZ-BLE PRoC module, which integrates PRoC BLE, two crystals, an on-board chip antenna, metal shield and passive components, all in a compact 10mm x 10mm x 1.8mm form factor. It includes Bluetooth 4.1 qualification and worldwide regulatory certification.

Designers looking to create Bluetooth Smart products must often use software tools from multiple vendors and develop complex firmware to meet wireless specifications. Cypress has abstracted the Bluetooth Low Energy protocol stack and profile configuration into a royalty-free, GUI-based BLE component that can be dragged and dropped into designs using Cypress' PSoC Creator IDE. PSoC Creator enables complete system design in a single tool, slashing time-to-market. 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.

Cypress offers the $49 CY8CKIT-042-BLE development kit, which gives users easy access to the Bluetooth Low Energy devices, while maintaining the design footprint from the PSoC 4 Pioneer kit. The kit includes a USB Bluetooth Low Energy dongle that pairs with the CySmart master emulation tool, converting a designer's Windows PC into a Bluetooth Low Energy debug environment. Cypress also offers two production-ready, reference design kits (RDK) that enable customers to get to market faster: the CY5672 Remote Control RDK and the CY5682 Touch Mouse RDK.

The 128KB flash versions of the PSoC 4 BLE and PRoC BLE solutions are sampling. Samples can be obtained by contacting Cypress sales or via Cypress' franchised distributors.
