1 The voltage regulator can generate VDDINT at levels of 1.00 V to 1.20 V with –5% to +5% tolerance when VRCTL is programmed with the sysctl API. This specification is only

guaranteed when the API is used.

2 Must remain powered (even if the associated function is not used).

3 VDDEXT is the supply to the voltage regulator and GPIO.

4 If not used, power with VDDEXT.

5 Balls that use VDDMEM are DATA15–0, ADDR19–1, ABE1–0, ARE, AWE, AOE, AMS3–0, ARDY, SA10, SWE, SCAS, CLKOUT, SRAS, SMS, SCKE. These balls are not tolerant

to voltages higher than VDDMEM.

6 When not using the USB peripheral on the ADSP-BF525/BF527 or terminating VDDUSB on the ADSP-BF523, VDDUSB must be powered by VDDEXT.

7 Bidirectional balls (PF15–0, PG15–0, PH15–0) and input balls (RTXI, TCK, TDI, TMS, TRST, CLKIN, RESET, NMI, and BMODE3–0) of the ADSP-

BF522/523/524/525/526/527 processors are 3.3 V tolerant (always accept up to 3.6 V maximum VIH). Voltage compliance (on outputs, VOH) is limited by the VDDEXT supply

voltage.

8 Parameter value applies to all input and bidirectional balls, except USB_DP, USB_DM, USB_VBUS, SDA, and SCL.

9 The VIHTWI min and max value vary with the selection in the TWI_DT field of the NONGPIO_DRIVE register. See VBUSTWI min and max values in Table 11 on Page 28.

10SDA and SCL are pulled up to VBUSTWI. See Table 11 on Page 28.
