10.1.16.2 3.3v and Low Strength
The following table describes all the parameters of a Bi-directional Buffer.
| Parameter | Value | Function |
|---|---|---|
| WIDTH | 1–99 (Limit may vary depend-ing on the family) | Data Width |
| VOLT (Flash Only) | 0,1,2,3,4,5 | Choice of different voltage levels. 3.3v (PCI), 3.3v and Low Strength, 2.5v and High Strength*, 2.5v and Low Strength*, 2.5v (Low Power) and High Strength or 2.5v (Low Power) and Low Strength |
| SLEW (Flash Only) | 0,1,2 | Choice of the slew rates: Low, Normal or High |
| PULLUP | NO/YES | Choice of Pull up version |
| TRIEN_POLARITY / EN_POLARITY (Flash) | 0,1 | Enable Polarity |
| TYPE (IGLOO,ProASIC3, SmartFusion, Fusion, Axcelerator and RTAX-S Only) | REG, S_8, S_12, S_16, S_24, F_8, F_12, F_16, F_24, LVCMOS25, LVCMOS18, LVCMOS15, PCI, PCIX, GTLP25, GTLP33, S_8U, S_12U, S_16U, S_24U, F_8U, F_12U, F_16U, F_24U, S_8D, S_12D, S_16D, S_24D, F_8D, F_12D, F_16D, F_24D, LVCMOS25U, LVCMOS25D, LVCMOS18U, LVCMOS18D, LVCMOS15U, LVCMOS15D, LVCMOS12, LVCMOS12D, LVCMOS12U, HSTL_I, SSTL2_I, SSTL2_II, SSTL3_I, SSTL3_II | Type of Buffer. "S" in S_* denotes Low Slew Rage and "F" in F_* denotes High Slew Rate. Also 8,12,16,24 denote Output drive strengths of 1x, 2x, 3x, 4x respectively |
