What is an EEPROM device?
Because EEPROM technology is used for some security gadgets, such as credit card, SIM card, key-less entry, etc., some devices have security protection mechanisms, such as copy-protection. EEPROM devices use a serial or parallel interface for data input/output. The common serial interfaces are SPI, I²C, Microwire, UNI/O, and 1-Wire.
What version of nspro do I need to use?
It is highly recommended to use the latest NsPro version. Autopower/Autoignition phone by the box. All phones must be connected without battery (except Zxxx phones) Older Ns Pro Boxes that use e-Gate smartcard work on Win 7 x64 and 32bit. New Ns Pro Boxes that use JCOP smartcard don’t work on Win 7 x64 bit. Ns PRO Box – 1 pc.
What is NS pro?
NS Pro uses the latest smart card security technology to assure a secure long term investment. NS Pro also implements a server authentication as an additional protection measure and increases level of customer service by providing regular update through the server. The server also provides instant news broadcasting to all customers.
What is EEPROM get and put in a serial connection?
EEPROM Get: Get values from EEPROM and prints as float on serial. EEPROM Iteration: Understand how to go through the EEPROM memory locations. EEPROM Put: Put values in EEPROM using variable semantics. EEPROM Update: Stores values read from A0 into EEPROM, writing the value only if different, to increase EEPROM life.
How many pins are there in an EEPROM?
These use from 1 to 4 device pins and allow devices to use packages with 8 pins or less. A typical EEPROM serial protocol consists of three phases: OP-code phase, address phase and data phase.
What is the op-code of EEPROM?
The OP-code is usually the first 8 bits input to the serial input pin of the EEPROM device (or with most I²C devices, is implicit); followed by 8 to 24 bits of addressing, depending on the depth of the device, then the read or write data. Each EEPROM device typically has its own set of OP-code instructions mapped to different functions.
What are the common operations on SPI EEPROM devices?
Common operations on SPI EEPROM devices are: Other operations supported by some EEPROM devices are: Parallel EEPROM devices typically have an 8-bit data bus and an address bus wide enough to cover the complete memory. Most devices have chip select and write protect pins.
