Manufacturer:TI Description:Pin Description Chip Select. Activates the device. When high, all outputs are tri-state and the device ignores other inputs. The part remains in a low power standby mode. When low, the part recognizes activity on the SCK signal. A falling edge on /CS must occur prior to every op-code. Serial Output. SO is the data output pin. It is driven actively during a read and remains tri-state at all other times including when /HOLD is low. Data transitions are driven on the falling edge of the serial clock. * SO can be connected to SI for a single pin data interface since the part communicates in half-duplex fashion. Write Protect. This pin prevents all write operations. If low, the part is completely write protected. If high, write access is determined by the other write protection features. A complete explanation of write protection is provided below. *Note that the function of /WP is different from the FM25160 where it protects the status register only. Ground Serial Input. All data is input to the device on this pin. The pin is sampled on the rising edge of SCK and is ignored at other times. It should always be driven to a valid logic level to meet ICC specifications. * SI may be connected to SO for a single pin data interface. Serial Clock. All I/O activity is synchronized to the serial clock. Inputs are latched on the rising edge and outputs occur on the falling edge. The part is static so the clock frequency may be any value between 0 and 2.1 MHz and may be interrupted at any time. Hold. The /HOLD signal is used when the host CPU must interrupt a memory operation for another task. Taking the /HOLD signal to a low state pauses the current operation. The part ignores any transition on SCK or /CS. All transitions on /HOLD must occur while SCK is low. Supply Voltage. 5V |
