Panasonic module cuts power for Bluetooth LE

Panasonic has introduced a Bluetooth module with what it claims is the industry’s lowest power Bluetooth Low Energy SoC. It is based on a chip from fellow Japanese company Toshiba.
 
The Pan 1760A module has a peak power consumption of 3.3mA in transmit and receive mode, enabling wireless functionalities in IoT, medical and industrial applications without compromising battery life. Mandatory and optional Bluetooth 4.2 features are supported.
 
The SMD device measures 15.6 by 8.7 by 1.9mm and the module is based on Toshiba's single chip TC35678 Bluetooth semiconductor device with embedded Toshiba Bluetooth 4.2 LE stack and embedded flash for user applications in stand-alone operation.
 
The product can either be operated in AT-command or host mode for simple integration of Bluetooth connectivity into existing products, or in stand-alone mode. In stand-alone mode, with 256kbyte flash memory and 83kbyte RAM for user application, it can be used for many applications without the need for an external processor, saving cost, complexity and space.
 
“Design engineers can easily migrate from using older versions of the Pan 1760, 1761 and 1026 modules to our new Pan 1760A component as all versions share exactly the same footprint,” said Pascal Meier, product manager at Panasonic. “The required code changes when migrating from Pan 1026 or Pan 1760 are only very minor. Previously developed software – Bluetooth Low Energy profiles and applications – can also easily be migrated with a minimal effort.”
 
The module is awaiting FCC, IC and CE approval.
