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

2 If not used, power with VDDEXT.

3 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.

4 The VPPOTP voltage for writes must only be applied when programming OTP memory. There is a finite amount of cumulative time that this voltage may be applied (dependent

on voltage and junction temperature) over the lifetime of the part. Please see Table 27 on Page 36 for details.

5 When not using the USB peripheral on the ADSP-BF524/BF526 or terminating VDDUSB on the ADSP-BF522, VDDUSB must be powered by VDDEXT.

6 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.

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

8 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.

9 SDA and SCL are pulled up to VBUSTWI. See Table 11.
