1.2
LCD Driver
The on-chip LCD driver includes many features that
make the integration of displays in low-power
applications easier. These include an integrated volt-
age regulator with charge pump that allows contrast
control in software and display operation above device
VDD.
1.3
Other Special Features
Communications: The PIC18F85J90 family
incorporates a range of serial communication
peripherals, including an Addressable USART, a
separate Enhanced USART that supports
LIN/J2602 Specification 1.2, and one Master SSP
module capable of both SPI and I2C (Master and
Slave) modes of operation.
CCP Modules: All devices in the family incorporate
two Capture/Compare/PWM (CCP) modules. Up to
four different time bases may be used to perform
several different operations at once.
10-Bit A/D Converter: This module incorporates
programmable acquisition time, allowing for a
channel to be selected and a conversion to be
initiated without waiting for a sampling period and
thus, reducing code overhead.
Extended Watchdog Timer (WDT): This
enhanced version incorporates a 16-bit prescaler,
allowing an extended time-out range that is stable
across operating voltage and temperature. See
time-out periods.

Details on Individual Family
Members
Devices in the PIC18F85J90 family are available in
64-pin and 80-pin packages. Block diagrams for the
two groups are shown in Figure 1-1 and Figure 1-2.
The devices are differentiated from each other in four
ways:
1.
Flash program memory (three sizes, ranging
from 8 Kbytes for PIC18FX3J90 devices to
32 Kbytes for PIC18FX5J90 devices).
2.
Data RAM (1024 bytes for PIC18FX3J90 and
PIC18FX4J90
devices,
2048
bytes
for
PIC18FX5J90 devices).
3.
I/O ports (7 bidirectional ports on 64-pin devices,
9 bidirectional ports on 80-pin devices).
4.
LCD Pixels: 132 pixels (33 SEGs x 4 COMs) can
be driven by 64-pin devices; 192 pixels
(48 SEGs x 4 COMs) can be driven by 80-pin
devices.
All other features for devices in this family are identical.
These are summarized in Table 1-1 and Table 1-2.
The pinouts for all devices are listed in Table 1-3 and
