1 _{The voltage regulator can generate VDDINT 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.
2 _{See Ordering Guide on Page 88.}
3 _{See Automotive Products on Page 87.}
4 _{Must remain powered (even if the associated function is not used).}
5 _{VDDEXT is the supply to the voltage regulator and GPIO.}
6 _{If not used, power with VDDEXT.}
7 _{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.
8 _{When not using the USB peripheral on the ADSP-BF525/ADSP-BF527 or terminating VDDUSB on the ADSP-BF523, VDDUSB must be powered by VDDEXT.}
9 _{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.
10_{Parameter value applies to all input and bidirectional balls, except USB_DP, USB_DM, USB_VBUS, SDA, and SCL.}
11_{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.
12_{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 on Page 29.}
13_{SDA and SCL are pulled up to VBUSTWI. See Table 11 on Page 29.}
