Billion ZigBee Module User Manual
(MD1000) DESCRIPTION The MD1000 module is a ZigBee network solution that integrates a 2.4Ghz, IEEE Cortex M3microprocessor. It contains 802.15.4-compliant transceiver with a 32 bit ARM integrated Flash and RAM memory and peripherals of use to designers of ZigBee-based applications. The transceiver utilized an efficient architecture in which the integrated receiver channel filtering allows for co-existence with other communication standards in the 2.4Ghz spectrum such as Wi-Fi and Bluetooth. An optional high performance radio mode (boost mode) is software selectable to boost dynamic range by a further 8dB. The highly integrated antenna, power regulator, and Xtal keep the external component count low. The internal PCB traced antenna and an external U.FL connector port is user selectable. This is maximum the flexibility for the designer to minimize the cost or maximize the system performance. The EM357 has 192kB of embedded Flash memory and 12kB of integrated RAM for data and program storage. The EM357 software stack employs an effective wear-leveling algorithm in order to optimize the lifetime of the embedded Flash. To support user-defined application, a number of peripherals such as GPIO, UART, SPI, I2C, ADC, and general purpose timers are integrated. Also, an integrated voltage regulator, power-on-reset circuitry, sleep timer, and low-power sleep modes are available. The deep sleep mode draws less than 2uA, allowing products to achieve long battery life. The equipped internal watch-dog timer allows the system to be reactivated once the system go into a dead-lock state. This mechanism makes the system more reliable and available. Target application for the MD1000 includes:
