CY62256VNLL-70ZXI

The temperature ranges for the CY62256VN Static RAM are as follows: - Commercial: 0°C to 70°C - Industrial: -40°C to 85°C - Automotive-A: -40°C to 85°C - Automotive-E: -40°C to 125°C

The writing/reading operation of the memory in the CY62256VN Static RAM is controlled by an active LOW write enable signal (WE) .

Memory expansion in the CY62256VN Static RAM is facilitated by an active LOW chip enable (CE) and active LOW output enable (OE) features, along with tri-state drivers. These features allow for easy memory expansion by controlling the writing/reading operation of the memory and enabling the outputs when needed. When both CE and WE inputs are LOW, data is written into the memory location addressed by the address present on the address pins. Reading the device is achieved by selecting the device and enabling the outputs, while WE remains inactive or HIGH. This allows the contents of the location addressed by the information on address pins to be present on the data input/output pins. The input/output pins remain in a high-impedance state unless activated.
