Panasonic – Place and Play Bluetooth® Low Energy Module


Figure 1: PAN1740 Series

A revolution is underway in Bluetooth Low Energy to dramatically shrink power budgets for battery powered applications. Panasonic’s “nanopower” family of 2nd generation BLE modules reduces transmit and receive current consumption by more than 66% when compared to the current generation of BLE devices and nearly a 90% reduction from Bluetooth Classic devices. Most significant is that these current reductions have been achieved without range reduction, without Tx power reduction and without changes to the Bluetooth specification.

The PAN1740 Series is Panasonic’s next generation “nanopower” Bluetooth Low Energy module with reduced form factor, significantly lower power consumption, embedded BLE stack and profile. Panasonic cost engineering lowers component count and the application BOM. The single mode Bluetooth system-on-chip module is optimized for lower power and small size. The power consumption of only 5mA in Tx or Rx mode allows for the use of coin cell batteries and reduces battery requirements up to 50% when compared to current generation BLE devices. With a fully shielded case, integrated crystal oscillators and chip antenna, the 9.0 x 9.5 x 1.8 mm footprint of the PAN1740 series make it one of the smallest BLE modules available. The PAN1740 Series is qualified to the Bluetooth 4.0 standard – FCC, IC, CE certifications are pending. Panasonic’s designer friendly Easy-to-Use (ETU) development kits reduce design efforts and critical time to market.
