M27C4002-90C1 Overview

A Non-Volatile-type memory can be classified as the memory type of this device. In addition, memory ics is available in a Tube case as well. As you can see, it is embedded in 44-LCC (J-Lead) case. It is estimated that the memory size on the chip is 4Mb 256K x 16. The device uses a mainstream EPROM-format memory. Due to its wide temperature range of 0°C~70°C TA, this device is well suited to a wide range of applications that require high performance. The device is capable of handling a supply voltage of 4.5V~5.5V volts. There is a recommendation that Surface Mount mounting type should be used for this product. As you can see from the diagram, the chip is planted with 44 terminations. This part supports as many as 1 functions for the comprehensive working procedure. An 5V supply is required for this ic memory chip to operate properly. Similar parts are frequently selected using M27C4002, the device's base part number. This memory device is enclosed in a 44-pin package. The memory device in question has 44 pins, thus indicating that it has 44 memory locations that can be accessed. The operating supply voltage of this memory chip is noted to be 5V. As for the power supply, this memory chip only needs 5V . A memory mapped I/O port address of COMMON bits is used in this device. It is able to operate from a max supply current of 0.07mA. The component is usually referred to as a type of OTP ROMs.
