programmable acquisition time, allowing for a
channel to be selected and a conversion to be
initiated without waiting for a sampling period,
thereby reducing code overhead.
for both program memory and data EEPROM are
rated to last for many thousands of erase/write
cycles – up to 100,000 for program memory and
1,000,000 for EEPROM. Data retention without
refresh is conservatively estimated to be greater
than 40 years.
to their own program memory spaces under inter-
nal software control. By using a bootloader routine
located in the protected Boot Block at the top of
program memory, it is possible to create an
application that can update itself in the field.
2523/4423/4523 family introduces an optional
extension to the PIC18 instruction set that adds
eight new instructions and an Indexed Addressing
mode. This extension, enabled as a device con-
figuration option, has been specifically designed
to optimize re-entrant application code originally
developed in high-level languages, such as C.
module provides one, two or four modulated
outputs for controlling half-bridge and full-bridge
drivers. Other features include auto-shutdown, for
disabling PWM outputs on interrupt or other select
conditions, and auto-restart, to reactivate outputs
once the condition has cleared.
communication module is capable of standard
RS-232 operation and provides support for the
LIN/J2602 bus protocol. Other enhancements
include automatic baud rate detection and a 16-bit
Baud Rate Generator for improved resolution.
When the microcontroller is using the internal
oscillator block, the EUSART provides stable
operation for applications that talk to the outside
world without using an external crystal (or its
accompanying power requirement).
Enhanced version incorporates a 16-bit prescaler,
allowing an extended time-out range that is stable
across operating voltage and temperature. See
Section 4.0 “Electrical Characteristics” for
time-out periods.
Other Special Features
1.3
Devices in the PIC18F2423/2523/4423/4523 family are
available in 28-pin and 40/44-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 these
ways:
• Flash Program Memory:
• A/D Channels:
• I/O Ports:
• CCP and Enhanced CCP Implementation:
• Parallel Slave Port – Present only on
All other features for devices in this family are identical.
These are summarized in Table 1-1.
The pinouts for all devices are listed in Table 1-2 and
Table 1-3.
