Description

PLL PowerÑVCCP is VCC dedicated for PLL use. The voltage should be

well-regulated and the input should be provided with an extremely low

impedance path to the VCC power rail.

Quiet Core (Low) PowerÑVCCQL is an isolated power for the core

processing logic. This input must be isolated externally from all other chip

power inputs. The user must provide adequate external decoupling

capacitors.

Quiet External (High) PowerÑVCCQH is a quiet power source for I/O lines.

This input must be tied externally to all other chip power inputs, except

VCCQL. The user must provide adequate decoupling capacitors.

Address Bus PowerÑVCCA is an isolated power for sections of the address

bus I/O drivers. This input must be tied externally to all other chip power

inputs, except VCCQL. The user must provide adequate external decoupling

capacitors.

Data Bus PowerÑVCCD is an isolated power for sections of the data bus I/O

drivers. This input must be tied externally to all other chip power inputs,

except VCCQL. The user must provide adequate external decoupling

capacitors.

Bus Control PowerÑVCCC is an isolated power for the bus control I/O

drivers. This input must be tied externally to all other chip power inputs,

except VCCQL. The user must provide adequate external decoupling

capacitors.

Host PowerÑVCCH is an isolated power for the HI08 I/O drivers. This

input must be tied externally to all other chip power inputs, except VCCQL.

The user must provide adequate external decoupling capacitors.

ESSI, SCI, and Timer PowerÑVCCS is an isolated power for the ESSI, SCI,

and timer I/O drivers. This input must be tied externally to all other chip

power inputs, except VCCQL. The user must provide adequate external

decoupling capacitors.
