Introducing the PAN1721, a complete power optimizedBluetooth v4.0 Low Energy (BLE) solution, this module includes an embedded processor, antenna and BLE stack. The PAN1721 is engineered for ultra low power consumption applications.
The PAN1721 is a cost-effective, ultra low-power, system-on-chip (SoC) for Bluetooth Low Energy applications. The module includes an eight channel, twelve bit analog-to-digital converter, 19 GPIOs plus battery and temperature sensors. A single device for both BLE master or slave nodes. The PAN1721 combines an excellent RF transceiver with a high performance low power 8051 microcontroller, in-system programmable flash memory, 8-KB RAM, and many other powerful supporting features and peripherals.
The PAN1721 is an ideal choice for applications where battery life is a critical application requirement, using only 500 nA in sleep mode. Short transition times between operating modes–3 uS Wake-Up – and power efficient hardware further reduce current consumption.
