Manufacturer:NICHICON Description:tRHEL, whichever occurs last. See the Ready/Busy Output section, Table 17 and Figure 11, Reset/ Temporary Unprotect AC Characteristics for more details. Holding RP at VID will temporarily unprotect the protected Blocks in the memory. Program and Erase operations on all blocks will be possible. The transition from VIH to VID must be slower than tPHPHH. Ready/Busy Output (RB). The Ready/Busy pin is an open-drain output that can be used to identify when the memory array can be read. Ready/Busy is high-impedance during Read mode, Auto Select mode and Erase Suspend mode. After a Hardware Reset, Bus Read and Bus Write operations cannot begin until Ready/Busy be- comes high-impedance. See Table 17 and Figure 11, Reset/Temporary Unprotect AC Characteris- tics. During Program or Erase operations Ready/Busy is Low, VOL. Ready/Busy will remain Low during Read/Reset commands or Hardware Resets until the memory is ready to enter Read mode. The use of an open-drain output allows the Ready/ Busy pins from several memories to be connected to a single pull-up resistor. A Low will then indicate that one, or more, of the memories is busy. Byte/Word Organization Select (BYTE). The Byte/ Word Organization Select pin is used to switch be- tween the 8-bit and 16-bit Bus modes of the mem- ory. When Byte/Word Organization Select is Low, VIL, the memory is in 8-bit mode, when it is High, VIH, the memory is in 16-bit mode. VCC Supply Voltage. The VCC Supply Voltage supplies the power for all operations (Read, Pro- gram, Erase etc.). The Command Interface is disabled when the VCC Supply Voltage is less than the Lockout Voltage, VLKO. This prevents Bus Write operations from ac- cidentally damaging the data during power up, power down and power surges. If the Program/ Erase Controller is programming or erasing during this time then the operation aborts and the memo- ry contents being altered will be invalid. A 0.1µF capacitor should be connected between the VCC Supply Voltage pin and the VSS Ground pin to decouple the current surges from the power supply. The PCB track widths must be sufficient to carry the currents required during program and erase operations, ICC3. VSS Ground. The VSS Ground is the reference for all voltage measurements. |
