Note: When a ' # ' is used at the end of the signal name, it indicates that the signal is active low. For example, RST# indicates that the reset signal is active low.

The buffer type for each signal is indicated in the 'Buffer Type' column of the pin description tables in Section 3.3, "Pin Descriptions". A description of the buffer types is provided in Section 1.2, "Buffer Types".

Table 3-1 details the 64-QFN package pin assignments in table format. As shown, select pin functions may change based on the device's mode of operation. For modes where a specific pin has no function, the table cell will be marked with '-'.

TABLE 3-1: 64-QFN PACKAGE PIN ASSIGNMENTS (CONTINUED)

Note 1: When powering this device from laboratory or system power supplies, it is important that the absolute maximum ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output. If this possibility exists, it is suggested to use a clamp circuit.

Note 2: This rating does not apply to the following pins: OSCI, RBIAS

Note 3: This rating does not apply to the following pins: RBIAS

Stresses exceeding those listed in this section could cause permanent damage to the device. This is a stress rating only. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Functional operation of the device at any condition exceeding those indicated in Section 18.2, "Operating Conditions*", Section 18.5, "DC Specifications", or any other applicable section of this specification is not implied. Note, device signals are NOT 5 volt tolerant.
