The table below summarizes the main differences between MAX8895X and MAX8895Y versions.
| Features/parameters | MAX8895X | MAX8895Y |
| Crystal | Internal (6MHz) | External (12MHz) |
| USB interface type | Low speed mode ( using an internal 6MHz oscillator, and does not require an external crystal to be USB compliant) | Full speed mode (requires an external 12MHz crystal) |
| Automatic switchable 1.5k pullup resistor | For D- | For D+ |
| Maximum input current drawn from VBUS in Standby mode (I_dectect_max) |
0.5mA | 2.5mA |
| Maximum input current drawn from VBUS in Suspend mode (I_suspend_max) |
0.5mA | 2.5mA |
| Automatic suspend mode detection enable pin (SUS_EN) | Yes | No |
| Automatic enumeration enable pin (/ENU_EN) | Yes | No |
| Wake up monitor line | D- | D+ |
| D+/- rise/fall time | 75ns-250ns | 4ns-20ns |
| Rise/fall time matching | 80-120% | 90-110% |
