Secure Bluetooth low energy plus NFC with zero-power standby
Based on a Toshiba SoC, the cost-effective PAN1761 Series supports both Bluetooth low energy functionality v4.1 and NFC through a NFC Forum Type 3 compliant tag. The module enables robust Bluetooth low energy central and peripheral nodes to be built with low total bill-of-material costs. The configuration of the device allows NFC to wake-up Bluetooth low energy from standby using a NFC field and automatically initiate a Bluetooth connection. Highly secure Bluetooth connections are created using NFC to exchange link keys (Out-of-Band pairing). Bluetooth low energy applications with extended battery life are possible as a result of zero power consumption in standby mode.
The PAN1761 device comes in a 15.6 x 8.7 x 1.8 mm surface mount package (same form factor as PAN1026 and PAN1760 Bluetooth modules) with RF transceiver, and programmable Bluetooth low energy EEPROM memory with 32 kB on-chip RAM for host-less operation of application software and driver. FStandard SIG Bluetooth low energy and “SPP over Bluetooth low energy” profiles, low-power sleep modes, short transition times between operating modes, and an operating temperature range from -40°C up to +85°C are included.
Panasonic adds: “In adding NFC technology to Bluetooth applications our customer can benefit of various security and power related features in their application. Security features are enabled through the so-called man-in-the-middle scenario by NFC technology. A NFC enabled remote control device, e.g. smartphone/tablet, must be physically close to the other device tol be connected. On the other hand NFC as enabler for Bluetooth connection set-up leads to ease-of-use in applications. This enables new areas of application in the diagnostic and maintenance systems.”
The low power consumption makes the new PAN1761 module a suitable choice for many applications such as healthcare and medical diagnostic systems without any human control interface, Bluetooth low energy sensor applications with a need to send data on request, diagnostic and maintenance systems with a requirement for zero standby power consumption, embedded wireless, wearable devices, mobile phone accessories, as well as industrial sensors and measurement devices.
An evaluation kit (PAN1761-EMK starter kit with NFC antenna) is available.
