ABSOLUTE MAXIMUM RATINGS
1
RECOMMENDED OPERATING CONDITIONS
Note: VCC I/O should not exceed VccInt by greater than 1.2V during the power-up sequence.
Note: Applying a logic high state to any I/O pin before VccInt becomes stable is not recommended.
Note: As specified in IEEE 1149.1 (JTAG), the JTMS pin must be held low during reset to avoid entering JTAG test mode. Refer to the
RM7000 Family Users Manual, Appendix E.

Note 1:
Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in
the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
