Technical Specifications:

The W24258S-70LI operates on a single 5V power supply. It has a typical operating current in the mA range and a standby current in the uA range. The device is available in various package options, including DIP and SOIC. The operating temperature range is typically 0°C to 70°C. The access time is a crucial specification, rated at 70ns, determining how quickly data can be read from the memory. The data retention voltage is typically 2V.

The device supports standard SRAM read and write operations. The address inputs are used to select one of the 32,768 memory locations. The data inputs/outputs are used to write data to or read data from the selected memory location. The chip enable (CE) input is used to activate or deactivate the device. The output enable (OE) input is used to control the output drivers. The write enable (WE) input is used to control the write operation.
