As far as its memory type goes, it falls into the Volatile category. There is a Tube case available. The 22-DIP (0.300, 7.62mm) case contains it. Memory size on the chip is 64Kb 64K x 1. There is a SRAM-format memory used in this device, which is the memory format used by mainstream devices. The device's extended operating temperature range of 0°C~70°C TA makes it ideal for many demanding applications. The supply voltage can be up to 4.5V~5.5V. Its recommended mounting type is Through Hole. It is planted on the chip with 22 terminations. For a comprehensive working procedure, this part supports as many as 1 functions. A voltage of 5V is required for the operation of this memory device. In order to select similar parts, typical manufacturers refer to CY7C187 as the device's base part number. It is encased in an 22-pin package that contains this ic memory chip. The memory device has a total of 22 pins, thus indicating that it has a total of 22 memory locations. As for the power supply, this memory chip only needs 5V . As part of the design, the I/O port addresses are mapped into the memory using an SEPARATE-bit number. It is able to operate from a max supply current of 0.09mA.
