This pin left open if ordered with capacitors already mounted in package. 2. HSB\ signal is wired to all 4 die in module. This can be left open if not used. Pin Name I/O Type Description A0 – A18 Address Inputs Used to Select one of the 524,288 bytes of the nvSRAM for x8 Configuration. A0 – A17 Address Inputs Used to Select one of the 262,144 words of the nvSRAM for x16 Configuration. DQ0 – DQ7 DQ0 – DQ15 DQ16 DQ23 DQ24 DQ31 WE\1 4 Input Write Enable Input, Active LOW. When selected LOW, data on the I/O pins is written to the specific address location. CE\1 4 Input Chip Enable Input, Active LOW. When LOW, selects the chip. When HIGH, deselects the chip. OE\ Input Output Enable, Active LOW. The active LOW OE input enables the data output buffers during read cycles. I/O pins are tri stated on deasserting OE HIGH. VSS Ground Ground for the Device. Must be connected to the ground of the system. VCC Power Supply Power Supply Inputs to the Device. HSB\ Input/Output Hardware Store Busy (HSB\). When LOW this output indicates that a hardware store is in progress. When pulled LOW external to the chip it initiates a nonvolatile STORE operation. A weak internal pull up resistor keeps this pin HIGH if not connected (connection optional). After each store operation HSB\ is driven HIGH for short time with standard output high current. VCAP Power Supply AutoStore Capacitor. Supplies power to the nvSRAM during power loss to store data from SRAM to nonvolatile elements. (leave pin open if caps mounted on package) NC No Connect No Connect. This pin is not connected to the die. Input Input/Output Bidirectional Data I/O Lines for die M1 (DQ0 7), M2 (DQ8 15), M3 (DQ16 23), M4 (DQ 24 31) |
