élanSC300 Microcontroller Data Sheet
P R E L I M I N A R Y
PIN STATE TABLES
The Pin State tables beginning on page 25 are grouped
by function based on their primary function when the
élanSC300 microcontroller is configured at reset for
the internal LCD Controller mode (NAME1). See
page 14 for a description of NAME1. The Pin State ta-
bles also show the I/O type and reset state for those
pins that have been configured at reset for either Local
Bus mode or Maximum ISA Bus mode.
Pin Characteristics
The following information clarifies the meaning of the
Pin State tables beginning on page 25:
The letters in the
I/O Type
column of Tables 1–10 mean
the following:
I
– Input
O
– Output
STI – Schmitt Trigger Input
B
– Bidirectional
A
– Analog
The
Term
column refers to internal termination. The
letters in this column of Tables 1–10 mean the follow-
ing:
PD – Pull-down resistor
PU – Pull-up resistor
The symbols (letters) in the
Drive Type
column specify
the drive capability of output pins. These specifications
can be found in the DC Characteristics section begin-
ning on page 80 of this document. For a more complete
description of I/O Drive Types, see “Derating Curves”
on page 84 and Table 48 on page 84.
The
Clock Off
column describes the logic level of the
I/O pins while the élanSC300 microcontroller is in any
of the power management modes where the CPU clock
is stopped, and power is still applied to both the VCCIO
and VCC clamp supply pins associated with that I/O
pin. For Doze mode, the data reflects a situation in
which the internal CGA controller video refresh is dis-
abled.
The
Reset State
column lists the I/O pin voltage level
when all of the VCC pins are stable and the RESIN
input is active. The level of the VCC pins correlating to
this data is shown in Table 1.
The
VCCIO
column refers to the voltage supply pin on
the élanSC300 microcontroller that is directly con-
nected to the output driver for the specified signal pin.
The
VCC Clamp
column refers to the voltage supply
pin on the élanSC300 microcontroller that is directly
connected to the ESD protection diode (cathode) for
the specified signal pin. Any pin with a 5-V VCC Clamp
is a “5-V safe” input.
The
Spec. Load
(specification load) column is used to
determine derated AC timing. See “Derating Curves”
on page 84 of this data sheet.
