RAM, SRAM is its memory type. As you can see from the diagram, the chip is planted with 84 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. It is encased in an 84-pin package that contains this ic memory chip. It has 84 pins indicating it has 84 memory locations. It is noted that the operating supply voltage of this memory is 5V. While this memory chip features many merits, it also offers INTERRUPT FLAG; SEMAPHORE; AUTOMATIC POWER-DOWN for improving system performance. An address can be read and/or written to one memory address using 2 ports on the chip. 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. A minimum operating temperature of -55°C must be met by this device. As a general rule, memory ics is recommended that the product be operated at temperatures no higher than 125°Cc, otherwise, damage could be done to it. This memory ics is capable of operating with an input current of 0.3mA at max. Generally, this component is considered a type of SRAMs.
