APEX LT PRODUCT SUMMARY

Product Description

The LS Research APEX LT module is a 2.4 GHz transceiver providing a solution for data

links and wireless networks. The module is based on the Ember EM260 network processor

providing an IEEE 802.15.4 radio transceiver with a SPI base interface. The SPI interface

gives the flexibility to choose the external microprocessor to best fit the application.

Key Features

• 100 mW output power

• Integrated antenna

• Supports MMCX connector for external antenna

• 16 RF channels (Channel 16 at a reduced power level)

• Output power is software controlled

• AES-128 encryption

• Constant RF output power over operating voltage range of 2.1 – 3.6V

• Integrated IEEE 802.15.4 PHY and MAC

• Dedicated network processor

• SPI-slave or UART interface to application microprocessor

• Handles all data processing and timing intensive tasks of Zigbee protocol

Specifications
