1 The expected nominal value is 1.4V ± 5% and initial customer designs should design with a programmable regulator that can be adjusted from 0.95V to 1.5V in 50mV steps.

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

3 VDDEXT is the supply to the GPIO.

4 If not used, power with VDDEXT.

5 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 because these

signals are multiplexed with GPIO.

6 The VDDOTP 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 17 on Page 26 for details.

7 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-

BF512/BF514/BF516/BF518(F) 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.

8 Parameter value applies to all input and bidirectional pins/balls except SDA and SCL.

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.

10SDA and SCL are pulled up to VBUSTWI. See Table 10.
