Preliminary Confidential Page 3 1. Introduction This note attempts to document the design of the hardware for the Statsignal FOCUS AMR section. The AMR section is intended to be integrated in a Landis+GYR FOCUS electric meter, in all of its meter forms. The FOCUS AMR section will allow remote data acquisition from the FOCUS meter and enable the FOCUS meter to be a part of the Statsignal RF network. The FOCUS AMR board uses the RFM radio transceiver part with OOK mode of operation. The FOCUS AMR section is qualified for operation between a temperature range of –40C to +85C at all humidities, from 0 to 100% relative humidity and condensing. A block diagram of the FOCUS AMR board is shown along with the major signal paths. The FOCUS AMR board consists of the following major functional blocks: 1) Power supply 2) Microcontroller 3) RF Transceiver 4) RSSI measurement 5) Serial I/O and interfacing In addition to the major blocks mentioned, there are some smaller connections used as test/debug points, for tilt detection and JTAG programming of the microcontroller.

Preliminary Confidential Page 4 2. Power supply The power supply circuit provides the regulated 3VDC (Vcc) required to power the different sections of the FOCUS AMR board. The power supply circuit performs three major functions: voltage monitoring and sensing, supplying backup power using a Supercapacitor, and voltage regulation. Confidential 385760.DOC Statsignal Systems, Inc. Preliminary Confidential Page 5 The primary source of power is the unregulated DC voltage (VUNREG) coming from the FOCUS metrology section. During normal operation, the raw DC voltage is fed through Schottky diode D900 to the LP2951ACM-3.0 regulator U903. The 3VDC output of this regulator (Vcc) is used to power the FOCUS AMR section. The raw DC voltage is also used to charge the Supercapacitor C900 through a current limiting circuit comprised of Q900, Q901 and R929, with resistor R929 setting the charging current. R903, Q902 and R902 allow the microcontroller to turn ON/OFF the charging of the Supercapacitor by controlling the state of the CHARGE pin. The zener diode D902 is used to protect the Supercapacitor from being overcharged in case there is a firmware malfunction that leaves the charging circuit on permanently. R904, Q904A and Q903 form an analog switch that is controlled by the state of the VCAPEN pin from the microcontroller. When VCAPEN is asserted, Q904A and Q903 turn on and the voltage present on the Supercapacitor is available on the drain pin of Q903. Resistors R905 and R906 form a voltage divider that scales this voltage down and allows the microcontroller to read the Supercapacitor voltage on the VCAP pin. Note that the analog switch will not turn on until the voltage across the Supercapacitor reaches the minimum turn-on threshold (Vgs) of P-Channel MOSFET Q903. Thus, the Supercapacitor voltage cannot be monitored below about 2 VDC. The microcontroller can periodically monitor the voltage on the Supercapacitor, and if it falls below a preset firmware threshold, it can turn on the charging circuit. Once the voltage on the Supercapacitor rises above another preset firmware threshold, the microcontroller can then turn off the charging circuit. In this way, the voltage on the Supercapacitor can be continuously topped off by the microcontroller. Resistors R901 and R902 form a voltage divider that scales down the raw input VUNREG voltage. This scaled down voltage, available on the VREF pin, allows the microcontroller to monitor the VUNREG voltage and detect AC mains power outage condition. The zener diode D903 is used as protection if VUNREG should rise too high. When there is an AC mains voltag…
