Working Principles

The AT27LV256A-70JC utilizes a technology called Electrically Erasable Programmable Read-Only Memory (EEPROM). It stores data by electrically charging specific memory cells, which can be read or modified as needed. The non-volatile nature of EEPROM ensures that the stored data remains intact even when power is removed.

When the chip enable (/CE) and output enable (/OE) signals are activated, the device allows access to the stored data. The address inputs (A0-A15) specify the location of the desired data, while the data inputs/outputs (I/O0-I/O3) facilitate reading from or writing to the memory.

Detailed Application Field Plans

The AT27LV256A-70JC finds application in various electronic systems that require reliable non-volatile storage. Some common application fields include:
