23A256-I/ST Product Details
23A256-I/ST Overview
Its memory type can be classified as Volatile. You can get memory ics in a Tube case. The 8-TSSOP (0.173, 4.40mm Width) case contains it. It is estimated that the memory size on the chip is 256Kb 32K x 8. There is a mainstream memory format used by this device, which is called SRAM-format memory. Due to its extended operating temperature range, the device is well suited for a wide range of demanding applications. A voltage of 1.7V~1.95V can be supplied to memory ics. It is recommended that the mounting type be Surface Mount. The chip is terminated with 8 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 1.8V power supply. In this memory, the clock frequency rotation is within an 20MHz range. 23A256, as the device's base part number, is frequently referred in order to select similar parts. A package of 8 pins is used to protect this memory device. I have noticed that the memory device has 8 pins, which indicates that it has 8 locations in the memory. This memory runs on an 1.8V operating supply voltage. Chips such as this one are mounted using Surface Mount mounting, a straightforward method of mounting that is effective. It is rated for a nominal supply current of 10mA for this memory component. An address can be read and/or written to one memory address using 1 ports on the chip. This device has SEPARATE-bit memory mapped I/O port addresses.
