M27C256B-90B6 [STMicroelectronics]

M27C256B-90B6 Overview

Non-Volatile is its memory type. It is available in a case with a Tube shape. As you can see, it is embedded in 28-DIP (0.600, 15.24mm) case. There is an 256Kb 32K x 8 memory capacity on the chip. In this device, the memory is of the EPROM-format, which is a popular format in the mainstream computing sector. Due to its extended operating temperature range, the device is well suited for a wide range of demanding applications. A voltage of 4.5V~5.5V is possible to be applied to the supply. There is a recommendation that Through Hole mounting type should be used for this product. As you can see from the diagram, the chip is planted with 28 terminations. In total, 1 functions are supported by this part. The memory device designed for this application has been designed to be powered by an 5V power supply. To select similar parts, many people use the device's base part number M27C256. It is encased in an 28-pin package that contains this ic memory chip. It has 28 pins indicating it has 28 memory locations. It is noted that the operating supply voltage of this memory is 5V. Chips such as this one are mounted using Through Hole mounting, a straightforward method of mounting that is effective. Memory chip's nominal supply current is 50mA. This memory chip requires a mere 5V of power. In addition to this device, there are COMMON-bit memory mapped I/O port addresses on this device. Generally, this component is considered a type of OTP ROMs.
