11. Block Diagram
12. Circuit Description
The module contains an IEEE 802.15.4 compliant SoC RF transceiver, internal memory,
high speed oscillator, RC oscillator, an FEM . 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 5μA , allowing products to achieve long battery life.
