Power Inputs
Power Name
Description
VCCQL
Quiet Core (Low) Power—An isolated power for the core processing and clock logic. This input must be isolated
externally from all other chip power inputs.
VCCQH
Quiet External (High) Power—A quiet power source for I/O lines. This input must be tied externally to all other chip
power inputs
, except VCCQL.
VCCA
Address Bus Power—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.
VCCD
Data Bus Power—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.
VCCC
Bus Control Power—An isolated power for the bus control I/O drivers. This input must be tied externally to all other
chip power inputs,
except VCCQL.
VCCH
Host Power—An isolated power for the HI08 I/O drivers. This input must be tied externally to all other chip power
inputs,
except VCCQL.
VCCS
ESSI, SCI, and Timer Power—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.
Note: The user must provide adequate external decoupling capacitors for all power connections.

Grounds
Name
Description
GND
Ground—Connected to an internal device ground plane.
Note: The user must provide adequate external decoupling capacitors for all GND connections.

Signal Description
EXTAL
Input
External Clock/Crystal Input—Interfaces the internal crystal oscillator input
to an external crystal or an external clock.
XTAL
Output
Chip-driven
Crystal Output—Connects the internal crystal oscillator output to an external
crystal. If an external clock is used, leave XTAL unconnected.
