Must remain powered (even if the associated function is not used).
If not used, power with V DDEXT .
Balls that use V DDMEM 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 .
The V PPOTP 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.
When not using the USB peripheral on the ADSP-BF524/ADSP-BF526 or terminating V DDUSB on the ADSP-BF522, V DDUSB must be powered by V DDEXT .
Parameter value applies to all input and bidirectional balls, except USB_DP, USB_DM, USB_VBUS, SDA, and S CL.
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.
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.
The V IHTWI min and max value vary with the selection in the TWI_DT field of the NONGPIO_DRIVE register. See V BUSTWI min and max values in
Table 11 .10
SDA and SCL are pulled up to V BUSTWI . See
Table 11 .Rev. D
