CHARACTERISTICS

Notes

1. The voltage level of the 5 V supply must always exceed or at least equal the voltage level of the 3.3 V supply during

power-up and power-down in order to guarantee protection against latch-up.

2. All digital inputs are 5 V tolerant except pin XIN.

3. IOH,IOL = ±4 mA for pins SACLK, SCL, SDA, SDAT, SCLT, TCK, TDI, TRST, TMS, TDO, GPIO, UNCOR, PSYNC,

OCLK, DEN and DO[7:0]. For all other pins, IOH, IOL = ±2 mA.
