Notes:
1. VccIO should not exceed VccInt by greater than 2.5 V during the power-up sequence.
2. Applying a logic high state to any I/O pin before VccInt becomes stable is not recommended.
3. For normal operation (non-boundary-scan), JTRST* must be pulled down to Vss (0 V) to avoid
entering JTAG test mode.
4. VccP must be connected to VccInt through a passive filter circuit. See RM79xx User Manual for
recommended circuit.
5. Power supply, D.C. characteristics, and A.C. timing are characterized across these operating ranges,
unless otherwise stated.
6. The VccInt and VccP voltages can be reduced (by 20 mV) to 1.30 V 50 mV if the RM7965A is
operated at 835 MHz or less.
