As far as its memory type goes, it falls into the RAM, SDR, SRAM category. Bulk-cases are available. It is estimated that the memory size on the chip is 16kB. On the chip, there are 84 terminations. The comprehensive working procedure is supported by 1 functions in this part. Memory devices such as this one are designed to be powered by 5V and should be used as such. In this ic memory chip, there is an 84-pin package that encloses the device. It has 84 pins indicating it has 84 memory locations. It is noted that the operating supply voltage of this memory is 5V. It also features INTERRUPT FLAG; AUTOMATIC POWER-DOWN; SEMAPHORE; BATTERY BACKUP to boost system performance despite all its merits. 2 ports allow read/write access to one memory address in this chip. As part of the design, the I/O port addresses are mapped into the memory using an COMMON-bit number. In order for this device to function properly, its operating temperature must not be less than 0°C. It is recommended for operation at temperatures no higher than. It is recommended that this part be supplied with at least 4.5V volts. An operating voltage of no more than 5.5V is required.
