AT28C256-20DM/883 Product Details

AT28C256-20DM/883 Overview


In terms of its memory type, it can be classified as Non-Volatile. The case comes in Tube size. The file is embedded in a 28-CDIP (0.600, 15.24mm) case. There is an 256Kb 32K x 8 memory capacity on the chip. Memory data is stored in EEPROM-format, which is common in mainstream devices. Due to its wide temperature range of -55°C~125°C TC, this device is well suited to a wide range of applications that require high performance. A supply voltage of 4.5V~5.5V can be applied to it. As far as the mounting type is concerned, Through Hole is recommended. It is planted on the chip with 28 terminations. For a comprehensive working procedure, this part supports as many as 1 functions. Memory devices such as this one are designed to be powered by 5V and should be used as such. Similar parts are frequently selected using the ic memory chip's base part number, AT28C256. The memory device has an 28-pin package, which encloses it in a small package. The memory chip utilizes a straightforward, high-efficiency mounting method, Through Hole mounting. In terms of its nominal supply current, this memory component is rated at 50mA. Nonvolatile memory arrays require 5V programming voltage to change their state. There is an 200GHz frequency with which this memory chip processes data.
