If it fails, the necessary personnel will be notified. 1.2 Power Up Sequence 1.2.1 The scope of this report shall be restricted to only the specifications of the Electronic Container Seal (ECS) of RFID project. 1.2.2 By no means it serves to provide reader with an understanding of the entire RFID project. 1.2.3 1.2.4 It serves to provide reader with an understanding of the specifications of the ECS. It starts by providing reader an overview of the system, outlining the necessary modules. 1.2.5 Transmission specifications were highlighted next to provide reader with some knowledge on the requirement of the transmitter. 1.2.6 The controller specifications, which include the Power-up Sequence, the Security Verification, Data Transmission, EEPROM Interface and Transmission Format, were presented for reader to understand the operation of the controller. It ends with a brief outline of the electrical characteristics of the ECS. 1.2.7 2.0 SYSTEM OVERVIEW P:\RFID\DOC\ECSSPEC2.DOC 7/31/2001 Page 2 Electronic Container Seal POWER SUPPLY CONTROLLER TRANSMITTER Confidential FM MEMORY Figure 1. Simplified ECS Block Diagram 2.0.1 The ECS consists of the blocks as shown above. 2.0.2 The controller provides the interface to the Memory. With the ECSs information stored in the memory, the controller will encode the number into FSK data before sending them to the transmitter to be modulated. 2.0.3 The memory provides storage space for the ECSs information. 2.0.4 The Transmitter is responsible for modulating the FSK data into FM signal. 2.0.5 The power supply shall come from a 3-Volt battery. 2.1 Power Up Sequence 2.1.1 The system shall be powered by external 3-volt battery. 2.1.2 The capacity of the battery shall be at least 1AH. 2.1.3 The shelf life with the battery shall be 1 year and the operating life will be 3 months. 2.2 Controller 2.2.1 2.2.2 Performing the necessary security verifications and ensure that the ECS is not It is the brain of the system. tampered. 2.2.3 Providing the interface to Memory, capable of reading and writing data into the memory. 2.2.4 Encode data from memory into FSK format before sending them to the transmitter. 2.3 Memory 2.3.1 It is a non-volatile memory large enough to sore the ECS data. P:\RFID\DOC\ECSSPEC2.DOC 7/31/2001 Page 3 Electronic Container Seal 2.3.2 It shall allow random read and write to its address. Confidential 2.4 FM Transmitter 2.4.1 This module is responsible to transmit the seal number to the Base Reader. 2.4.2 Its responsible is to module the FSK data into FM signal before sending it over the air. 3.0 RF TRANSMISSION SPECIFICATIONS 3.0.1 The ECS sends its seal number to the Base Reader via Radio Frequency (RF). 3.0.2 The ECS has a 433.92MHz RF transmitter, which transmits 433.92MHz FM signal. 3.0.3 It receives data from the Controller. The data from the Controller is FSK encoded and the amplitude shall be 0 to VCC. 3.0.4 The FSK data shall then be frequency modulated into 433.92MHz FM signal. 3.0.5 The Oscillator shall use a SAW Resonator type circuit. 3.0.6 The transmitter output impedance shall be 50W 3.0.7 When no transmission is required, the power to it shall be switched off. 3.0.8 All Specifications must meet the FCC Standard Part 15 and Europe Standard

Power Up Sequence 4.1 4.1.1 An ECS can only be powered once. Subsequent power up will be regarded as tampered and tamper code will be sent in addition to the stored data. 4.1.2 The power up sequence of the controller shall be as follow:
