The memory is accessed by a simple SPI bus compatible serial interface. The bus signals are a serial clock input (C), a serial data input (D) and a serial data output (Q). The device connected to the bus is selected when the chip select input (S) goes low. Data is clocked in during the low to high transition of clock C, data 8 1 SO8 (MN) 150 mil width 8 1 SO8 (MW) 200 mil width Figure 1. Logic Diagram VCC Table 1.
