12. Circuit Description
The module contains an IEEE 802.15.4 compliant RF transceiver, high speed oscillator,
RC oscillator and RF FEM . The module is intended to running the Ember ZigBee
software or other ZigBee network implementation, depending on the specific version.
The application software together with the ZigBee protocol software stack can be
programmed in Flash memory through SIF module, using an evaluation board from
Ember InSight Desktop.
To support user-defined applications, the module exposes the Ember Serial API over the
SPI, which allows application development to occur on a Host microcontroller of choice.
In addition to the four SPI signals, two additional signals, nHOST_INT and nWAKE,
provide an easy-to-use handshake mechanism between the Host and the module. 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 5μA allowing products
to achieve long battery life.
