Hi,
We are interfacing MT29F2G16ABBEAH4-IT with AM335X.
While doing DC analysis of Voh and Vol we found that AM335X VOL is not satisfied with MT29F2G16ABBEAH4-IT VIL and AM335X VOH is not satisfied with MT29F2G16ABBEAH4-IT VIH. We are driving AM335X and MT29F2G16ABBEAH4-IT from TPS65910 VDIG (1.746 to 1.854).
Below is analysis table.Please let me know if we can not interface MT29F2G16ABBEAH4-IT with AM335X.?

MPU VOL |
|
|
0.45 |
VOL < VIL is not satisfied.
|
|
NAND FLASH : VIL |
-0.3 |
_ |
Vcc min x 0.2 = 0.349 Vcc max x 0.2 = 0.370 |
|
|
|
|
|
|
|
|
MPU VOH |
VDDSHV1 min – 0.45 = 1.296 VDDSHV1 max – 0.45 = 1.404 |
|
|
VOH > VIH is not satisfied.
|
|
NAND FLASH: VIH |
Vcc min x 0.8 = 1.3968 Vcc max x 0.8 = 1.3968 |
|
Vcc min + 0.3 = 1.446 Vcc max + 0.3 = 2.154 |
