† All typical values are at VDD = 5 V, TC = 25°C.

‡ All input and output voltage levels except RS, INT0 – INT3, NMI, CNT, X2/CLKIN, CLKMD0 – CLKMD3 are TTL-compatible.

§ Clock mode: PLL

× 1 with external source

¶ This value was obtained with 50% usage of MAC and 50% usage of NOP instructions. Actual operating current varies with program being

executed.

# This value was obtained with single-cycle external writes, CLKOFF = 0 and load = 15 pF. For more details on how this calculation is performed,
