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 V_DDMEM.
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 30 on Page 38 for details.
5 _{When not using the USB peripheral on the ADSP-BF524/ADSP-BF526 or terminating VDDUSB on the ADSP-BF522, VDDUSB must be powered by VDDEXT.}
6 _{Parameter value applies to all input and bidirectional balls, except USB_DP, USB_DM, USB_VBUS, SDA, and SCL.}
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-BF52x processors are}
2.5 V tolerant (always accept up to 2.7 V maximum V_IH). Voltage compliance (on outputs, V_OH) is limited by the V_DDEXT supply voltage.
8 _{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-BF52x processors are}
3.3 V tolerant (always accept up to 3.6 V maximum V_IH). Voltage compliance (on outputs, V_OH) is limited by the V_DDEXT supply voltage.
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.}
10_{SDA and SCL are pulled up to VBUSTWI. See Table 11.}
