The voltage regulator can generate V DDINT at levels of 1.00 V to 1.20 V with –5% to +5% tolerance when VRCTL is programmed with the bfrom_SysControl() API. This

specification is only guaranteed when the API is used.

See Ordering Guide on Page 88 .

See Automotive Products on Page 87 .

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

V DDEXT is the supply to the voltage regulator and GPIO.

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 .

When not using the USB peripheral on the ADSP-BF525/ADSP-BF527 or terminating V DDUSB on the ADSP-BF523, V DDUSB must be powered by V DDEXT .

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.

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

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 on Page 29 .

SDA and SCL are pulled up to V BUSTWI . See Table 11 on Page 29 .
