... CS (Chip select input) Pin This is an input pin to set a chip in the select status. In the “H” input level, the device is in the non-select status and its output is high impedance. The device is in standby as long not in Write inside. The device goes in active by setting the chip select to “ ...

... Instruction Setting Table 16 is the list of instruction for the S-25C080A. The instruction is able to be input by changing the CS pin “H” to “L”. Input the instruction in the MSB first. Each instruction code is organized with 1-byte as shown below. If the S- 25C080A receives any invalid instruction code, the device goes in the non-select status. ...

... Bit WEL shows the status of internal Write Enable Latch. Bit WEL is set by the WREN instruction only. If bit WEL is “1”, this is the status that Write Enable Latch is set. If bit WEL is “0”, Write Enable Latch is in reset, so that the device does not receive the WRITE or WRSR instruction. Bit WEL is reset after these operations; ...

... Before writing data (WRITE and WRSR), be sure to set bit Write Enable Latch (WEL). This instruction is to set bit WEL. Its operation is below. After selecting the device by the chip select ( CS ), input the instruction code from serial data input (SI). To set bit WEL, set the device in the non-select status the 8th clock of the serial clock (SCK). To cancel the WREN instruction, input the clock different from a specified value ( clock) while “ ...

... These are two statues when bit SRWD is set to “1”. • Write in the status register is possible; Write protect ( “H”. • Write in the status register is impossible; Write protect ( “L”. Therefore the Write protect area which is set by protect bit (BP1, BP0) in the status register cannot be changed. ...

... CS pin is in the non-select status “H”. Set the CS pin to V resistor 100 kΩ. To prevent the error for sure recommended to set other input pins than the CS pin via a pull-up resistor. 2. Equivalent circuit of I/O pin Figure 21 and 22 show the equivalent circuits of input pins in S-25C080A. A pull-up and pull-down elements are not included in each input pin, pay attention not to set it in the floating state when you design. Figure 23 shows the equivalent circuit of the output pin. This pin has the tri-state output of “ ...
