Bluetooth Smart module integrates programmable analog and digital blocks
Sensor-based systems require an Analog Front End (AFE) for sensing, digital control logic, a BLE radio and a microcontroller, and products with a sophisticated user interfaces require an additional touch or display IC.
Based on Cypress’s PSoC 4 BLE Programmable System-on-Chip with an ARM Cortex-M0 core, the EZ-BLE PSoC module integrates all of the building blocks of a sensor-based system, along with the company’ CapSense capacitive touch-sensing functionality, two crystals, an on-board trace antenna, metal shield and passive components.
Customers designing with the module can apply to add the Bluetooth logo on their products by referring to Cypress’s Qualification Design Identification (QDID), a unique serial number assigned by the Bluetooth SIG.
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’s PSoC Creator integrated design environment (IDE).
PSoC Creator enables complete system design in a single tool. Application details for Cypress’s BLE Component are embedded in PSoC Creator with examples of all supported Bluetooth Low Energy profiles and hundreds of example projects for mixed-signal system designs.
The EZ-BLE PSoC module enables designers to create custom AFEs for sensor interfaces using programmable analog blocks such as opamps, comparators, ADCs and DACs. Designers can integrate digital logic with the programmable digital blocks, which include Timers, Counters, Pulse-Width Modulators (TCPWMs), Serial Communication Blocks (SCBs) and Universal Digital Blocks (UDBs).
The EZ-BLE PSoC module is currently sampling with production expected in the fourth quarter of 2015. It is available in a 32-pad SMT module with 25 GPIOs, 128KB flash and 16KB of SRAM and is ideal for space-constrained applications.
