Basic knowledge of SIM card application skills

microprocessor, 5 modules, each module corresponds to a function: CPU (8 bits), program memory ROM (6-16kbit), working memory RAM (128-256KBIT), Data memory EEPROM (2-8kbit) and serial communication unit , these 5 modules are integrated into a single integrated circuit. The SIM card requires a minimum of 5 connectors when connecting to the phone: * Power supply (VCC) * Clock (CLK) * Data i/q Port * Reset (RST) * Grounding End (GND) (3) The 20 digit I

specific location in the SDH frame. On the contrary, it allows the user's net load to fluctuate within the frame, use the pointer in the overhead field to indicate the starting position of the user's net load. In the user's opinion, SDH is a physical layer medium that provides byte synchronization.3 ATM OverviewATM is a connection-oriented transmission mechanism based on CELL). A fixed 53-byte atm cell facilitates hardware-based exchange. The ATM uses a VCC

uniform standard. Shows the UART position on the motherboard of the WRT54G router. It is found through observation that the box in the words "JP1" is the serial port location of the WRT54G router board most compliant with the URAT sign. The serial number of the pin has been indicated on the motherboard to locate each pin. After finding the serial port of the router, we need to differentiate the functions of these pins. The following two methods are provided. Through the combination of these two

Introduction of China Telecom OCS

With the evolution of the network and the intensification of competition in the telecom market, the telecom billing system is gradually changing. In terms of network capabilities, the billing system must constantly meet the Billing needs of fixed network, PHS, GSM mobile network, broadband network, 3G mobile network, and other network services. In terms of market demands, the rapid increase in the proportion of prepaid users poses a huge challenge for

Transistor as a switch to learn

Transistor as a switch, is the transistor working in the saturation zone, the NPN transistor as an example (all of the following) As shown in the figure: when the vin=0, transistor b-e There is no forward bias, and cutoff, equivalent to the state of disconnection, at this time vce=vcc,c pole current ic=0; When the transistor is closed (in the saturation zone), the load RC and transistor equivalent in series, through the RC current, through Ohm's Law,

Transistor switch circuit design

ensure that the transistor must be in the cutoff state.2, enter the saturation zone condition: First collector to be connected to a load resistor R1, the base to be connected to a base resistor R2, as shown in figure. 1. To transmit the current to the load, the transistor collector and emitter must be shorted. It is therefore necessary to have VIN reach a sufficiently high potential to drive the transistor into the saturated working area. When the transistor is saturated, the collector current

Transistor depth Saturation analysis

Transistor Saturation Problem Summary:1. In practical work, the common ib*β=v/r is used as the condition for judging the critical saturation. According to the IB value calculated by IB*Β=V/R, only the transistor enters the initial saturation, in fact should take the value of more than a few times to achieve true saturation, the larger the multiplier, the deeper the saturation .2. The larger the collector resistance, the more easily saturated;3. Saturation zone phenomenon is: Two PN junction is p
