Notes:
1. âTypâ parameter applies when Controller ROUTH = 40ï and SRAM RINH = RINL = 120ï.
2. âTypâ parameter applies when Controller ROUTL = 40ï and SRAM RINH = RINL = 120ï.
3. VREFac is equal to VREFdc plus noise.
4. VIH max and VIL min apply for pulse widths less than one-quarter of the cycle time.
5. Input rise and fall times must be a minimum of 1V/ns, and within 10% of each other.
6. Parameters apply to High Speed Inputs: CK, CK, KD, KD, SA, D, R, W, MRW.
7. Parameters apply to Low Speed Inputs: RST, PLL, MZT, PZT.
