This pin is opendrain driven and may be wireored with any number of other opendrain or open collector devices. The serial eeprom requires only 10% of the board space that a parallel eeprom requires. This module is based on the eeprom chip at24c256, which has 256k bit capacity. How the device works the read only memory cell usually consists of a single transistor rom and eprom cells consist of one transistor, eeprom cells consist of one, oneandahalf, or two transistors.

Designed to perform in tactical and other harsh environments, the isb token is constructed of a rugged material that protects the embedded memory and is resistant. The microchip at24c512c is a 512kb serial eeprom utilizing an i 2 c 2wire serial interface. There\s this software protection too, i\ve tried to do the unprotect procedure even though the datasheet states the chips shall not be protected coming from the factory but no luck. The 8k eeprom only uses the a2 device address bit with the next 2 bits being for memory page addressing. Using serial eeproms 1997, 1999 by jan axelson if you have a project that needs a modest amount of nonvolatile, readwrite memory, serial eeprom may be the answer. Microchips serial eeprom products are compatible with five serial bus types and support densities that range from 128 bits up to 2 mbits. For now, i\ve fixed up the wiring of my project to support both 2k and 8k eeproms. If you need to do some data storage in arduino but found that the eeprom in atmega chip too limited, then this i2c eeprom module is your best choice. Ci eeprom 2816 eeprom 2816 threshold sensor max16032. It also didnt found a device, but when i removed the pull ups, the library scan function wrote there is a problem with the bus, could not complete scan so i think we can assume that the pull up part is assembled in the right way. Datakey i2c eeprom bar memory tokens the isb bar series token is a portable data carrier containing 1 kbit to 256 kbit nonvolatile, serial i 2c eeprom memory that is completely sealed against moisture and other corrosive elements. To order, add the package identifier to the part number. The memory is accessed via a simple serial peripheral interface spi compatible serial bus.
The scl input is used to positive edge clock data into each eeprom device and negative edge clock data out of each device. At28c16 16k 2k x 8 parallel eeproms stanford cva group.
