1 Must remain powered (even if the associated function is not used).
2 VDDEXT is the supply to the GPIO.
3 Pins/balls that use VDDMEM are DATA15–0, ADDR19–1, ABE1–0, ARE, AWE, AMS1–0, SA10, SWE, SCAS, CLKOUT, SRAS, SMS, SCKE. These pins/balls are not tolerant
to voltages higher than VDDMEM. When using any of the asynchronous memory signals AMS3–2, ARDY, or AOE VDDMEM and VDDEXT must be shorted externally.
4 If not used, power with VDDEXT.
5 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.
6 Bidirectional pins/balls (PF15–0, PG15–0, PH7–0) and input pins/balls (RTXI, TCK, TDI, TMS, TRST, CLKIN, RESET, NMI, and BMODE2–0) of the ADSP-BF51x 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 pins/balls except 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 8.
9 SDA and SCL are pulled up to VBUSTWI. See Table 8.
