For an assignment for school I need to interface a EEPROM(24LC256) chip to the Rpi using the I2C interface.
EEPROM (also E 2 PROM) stands for electrically erasable programmable read-only memory and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless systems, and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed. Electrically Erasable PROM, capable of operation across a broad voltage range (1.7V to 5.5V). element14 offers special pricing, same day dispatch, fast delivery, wide inventory, datasheets & technical support. 2.0 PIN DESCRIPTIONS 2.1 A0, A1, A2 Chip Address Inputs The A0, A1, A2 inputs are used by the 24xx256 for multiple device operation. 1.04 DC ELECTRICAL CHARACTERISTICS Test Conditions: Test Circuit of Figure 2 Vcc = 12V, TA = 25°C, C = 0.01 F, R1 = 100k , R2 = 10k , R3 = 25k Unless Otherwise Specified. The pins on the 24LC256 are pretty straightforward and consist of power(8), gnd(4), write protection(7), SCL/SDA(6,5), and three address pins(1,2,3).

This model also has selectable device addresses using three pins, so we can use up to eight at once on the same bus.
It is nothing more than individual tactile keys.
24.2 I2C BUS CHARACTERISTICS The I2C bus is a two-wire serial interface.Figure 24-2 shows a schematic of an I2C connection between a PIC24F device and a 24LC256 I2C serial EEPROM, which is a typical example for any I2C interface. The levels on these inputs are compared with the corresponding bits in the slave address. The client/user can change the quality of certain units without expecting to erase the programming on different cells. If you need 24LC256 I/SM and any information about it, please feel free to contact us anytime.
By using mixed technologyit has been possibleto optimize the logic circuitry and the power stage to achieve the best possible performance. 24LC256-I/ST PDF - Documentation language en size 0.72 MB The documentation is not updated automatically, but we make every effort to provide the latest versions of the documents. The DMOS output transistors can operate at supply voltages up to 42V and efficiently at high switch-ing speeds. Consequently, areas of data might be erased and replaced without expecting to adjust whatever rest of the chip programming. 24LC256/P price list from semiconductor and transistor:We offer you the best 24LC256/P price,photo,transistor and 24LC256/P semiconductor.
Description An EEPROM is an Electrically Erasable Programmable Read Only Memory chip. If you are using one of these devices please read the document located at 24AA256/24LC256/24FC256 Data Sheet. The A0, A1, A2 pins are used by the 24LC256 device for multiple device operation. The 24LC256 is a 256K bits Electrically Erasable PROM with 2-wire I2C compatible serial interface. Usually this will be the chip supply, VCC, but for very low logic voltages it is necessary to use a VCC of at least 3.3 V and preferably even higher.
2.3 Chip enable (E2, E1, E0) (E2,E1,E0) input signals are used to set the value that is to be looked for on the three least significant bits (b3, b2, b1) of the 7-bit device select code (see Table 3). The 24LC256-I/P is a 256kb (32k x 8) I²C™ CMOS serial Electrically Erasable PROM (EEPROM) capable of operation across a broad voltage range (1.7 to 5.5V).
