Unlock the potential of voice-based distant controls with the reference design, supporting Bluetooth low vitality (BLE), ZigBee, and multi-standard protocols.
Distant controls function handy and environment friendly technique of wirelessly controlling varied gadgets. These distant controls have revolutionized our interplay with electronics, permitting us to regulate gadgets with out direct contact. Whether or not altering tv channels, adjusting the sound system’s quantity, or working a sensible dwelling machine, radio frequency (RF) and Infrared (IR) distant controls have turn out to be indispensable instruments. Texas Devices (TI) has launched the reference design of a voice distant management to simplify the design course of. The CC2650 distant management reference design is a complete resolution for growing voice-based distant controls supporting Bluetooth low vitality (BLE), ZigBee, or multi-standard protocols. The design showcases an optimized structure for decoupling and RF efficiency. By using discrete parts for the balun and filter, together with an inverted F printed circuit board (PCB) antenna, the design achieves glorious RF efficiency at an reasonably priced price. The distant management is designed to cater to numerous purposes corresponding to RF distant management, IR distant management, movement monitoring, and so on.
The design relies on the multistandard wi-fi microcontroller (MCU) designed for ultra-low energy consumption, meant explicitly for Bluetooth Sensible, ZigBee, IPv6 over Low energy Wi-fi Private Space Networks (6LoWPAN), and ZigBee distant management purposes. The MCU has a 32-bit ARM Cortex M3 foremost processor operating at a clock velocity of 48 MHz. The design includes a compact load swap with low resistance, that includes a managed ON and OFF enter turn-on. It’s designed to interface instantly with low-voltage general-purpose enter/output (GPIO) management indicators. The reference design additionally incorporates an 8-bit parallel-out serial-shift register particularly designed for operations with VCC starting from 2V to five.5V. Its broad working vary makes it appropriate with varied programs using totally different logic ranges. With its low propagation delay, it permits quick switching and high-speed operation. Moreover, the low-ground bounce characteristic stabilizes the efficiency of non-switching outputs whereas facilitating the switching of one other output.
The distant management has 1MB of exterior flash reminiscence, enabling knowledge and firmware storage. The distant management additionally includes a DevPack growth header, permitting extra performance and customization. The design consists of 32 steel dome buttons, a bi-coloured light-emitting diode (LED), a nine-axis micro-electrical-mechanical system (MEMS) movement sensor, a digital microphone, an infrared (IR) LED, 1MB of exterior flash, and a buzzer.
TI has examined this reference design. It comes with a Invoice of Materials (BOM), schematics, Gerber file, Printed circuit board (PCB) structure, computer-aided design/ computer-aided engineering (CAD/CAE) symbols, and so on.
