Product Summary
The U62256ADC-07LL is a standard 32K X 8 SRAM manufactured using a CMOS process technology with the following operating modes: Read - Standby, Write - Data Retention The U62256ADC-07LL memory array is based on a 6-transistor cell. The U62256ADC-07LL circuit is activated by the falling edge of E. The address and control inputs open simultaneously. According to the information of W and G, the data inputs, or outputs, are active. In a Read cycle, the U62256ADC-07LL data outputs are activated by the falling edge of G, afterwards the data word read will be available at the outputs DQ0-DQ7. After the address change, the data outputs go High-Z until the new information read is available. The data outputs have not preferred state.
