Recommended Operating Conditions for LH7A404-N0E-092-xx/LH7A404-N0F-092-xx
NOTES:
1. Core Voltage should never exceed I/O Voltage after initial power up. See “Power Supply Sequencing” on page 31.
2. Many blocks do not operate properly at speeds other than 14.7456 MHz. Some (such as USB) function only at 14.7456 MHz.
NOTE: *LH7A404-N0E-000-xx and LH7A404-N0F-000-xx only. Table 8 is representative of a typical device.
