2 The voltage regulator can generate VDDINT at levels of 0.85 V to 1.2 V with –5% to +10% tolerance. To run the processors at 500 MHz or 600 MHz, VDDINT must be in an
operating range of 1.2 V to 1.32 V.
3 Bidirectional pins (DATA15–0, PF15–0, PG15–0, PH15–0, TFS0, TCLK0, RSCLK0, RFS0, MDIO) and input pins (BR, ARDY, DR0PRI, DR0SEC, RTXI, TCK, TDI, TMS,
TRST, CLKIN, RESET, NMI, and BMODE2–0) of the ADSP-BF534/ADSP-BF536/ADSP-BF537 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.
4 Parameter value applies to all input and bidirectional pins except CLKIN, SDA, and SCL.
5 Parameter value applies to CLKIN pin only.
6 Pins SDA, SCL, and PJ4 are 5.0 V tolerant (always accept up to 5.5 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 except SDA and SCL.
