Circuit Description
The module contains an IEEE 802.15.4 compliant SoC RF transceiver, internal
memory, high speed oscillator, RC oscillator and an external 32 kHz oscillator. The
module is intended to run the EmberZNet 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 the SIF module, using an evaluation board
from Ember InSight Desktop.
To support user-defined applications, 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 1μA (need to further verification),
allowing products to achieve long battery life.
