Saves Time and Money / Reduces Risk 11 Chip or Module ?

• Requirements Dictating a Chip Design • Form factor (in extreme cases) • Long design cycle is acceptable • Very high volume, where optimized BOM out-weighs R&D investment and timescales • > 200k per annum • RF design experience is essential • RF Test Equipment available • Protocol stack experience is essential • Conformance & certification experience is essential • Specialist R&D & production line test equipment is essential

• Requirements Dictating a Module Design • Low to medium volume, where R&D investment and TTM is the priority • < 200k per annum • Where ever the application platform is decoupled from the wireless technology • i.e. multiple derivatives with WiFi, Bluetooth, Zigbee, LoRa etc • Prototypes or trials, where there is technology or commercial risk • Go to market quickly with a module solution, convert to an optimised chip design when proven

32 Beacons

• Microchips BLE IC’s and Modules are capable of supporting iBeacon & Eddystone™ iBeacon • These standard beacons are provisioned at a particular spot (like a coat rack in a retail store) • When you approach the beacon it invokes an application (such as a loyalty app) on your phone.

• The app can then communicate with the cloud and log Eddystone™ that you are in the particular retail store and send you offers and incentive coupons. • There is no two-way communication with the beacon!
