As far as its memory type goes, it falls into the Volatile category. There is a Tube case available. The file is embedded in a 28-SOIC (0.330, 8.38mm Width) case. Memory size on the chip is 256Kb 32K x 8. In this device, the memory is of the SRAM-format, which is a popular format in the mainstream computing sector. Suitable for use in a wide range of demanding applications, this device offers an extended operating temperature range of -40°C~85°C TA. A supply voltage of 4.5V~5.5V can be applied to it. The recommended mounting type for this device is Surface Mount. On the chip, there are 28 terminations that are planted. There are 1 functions supported by this part as part of the comprehensive working process. 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 28-pin package that encloses the device. It has 28 pins indicating it has 28 memory locations. This memory chip has an operating supply voltage of 5V. There are 1 ports used in this chip to give read and/or write access to one memory address. When it comes to power supplies, this memory chip only requires 5V . As part of the design, the I/O port addresses are mapped into the memory using an COMMON-bit number. As far as the supply current is concerned, it can be operated with a maximum of 0.07mA of currentThe memory runs at a maximum frequency of up to 14MHz cycles per second.
