In this case, the memory type of the device can be classified as Volatile. There is a Tape & Reel (TR) case available. In the case of 28-BSOJ (0.300, 7.62mm Width), it is embedded within the case. It is estimated that the memory size on the chip is 256Kb 32K x 8. This device utilizes a SRAM format memory which is of mainstream design. With an extended designed operating temperature of -40°C~85°C TA, this device is capable of lots of demanding applications. It is capable of handling a voltage supply of 4.5V~5.5V. As far as the mounting type is concerned, Surface Mount is recommended. On the chip, there are 28 terminations that are planted. In total, 1 functions are supported by this part. The memory device is designed to be supplied with an 5V volt power supply in order to operate properly. It is encased in an 28-pin package that contains this ic memory chip. A memory device with 28 pins means that it contains 28 memory locations, indicating that it has 28 pins.
