PIC18F6310/6410/8310/8410
1.2 Other Special Features
Memory Endurance: The Flash cells for program
memory are rated to last for approximately a
thousand erase/write cycles. Data retention
without refresh is conservatively estimated to be
greater than 100 years.
External Memory Interface: For those
applications where more program or data storage
is needed, the PIC18F8310/8410 devices provide
the ability to access external memory devices.
The memory interface is configurable for both
8-bit and 16-bit data widths and uses a standard
range of control signals to enable communication
with a wide range of memory devices. With their
21-bit program counters, the 80-pin devices can
access a linear memory space of up to 2 Mbytes.
Extended Instruction Set: The
PIC18F6310/6410/8310/8410 family introduces
an optional extension to the PIC18 instruction set,
which adds 8 new instructions and an Indexed
Addressing mode. This extension, enabled as a
device configuration option, has been specifically
designed to optimize re-entrant application code
originally developed in high-level languages such
as ‘C’.
Enhanced Addressable USART: This serial
communication module is capable of standard
RS-232 operation and provides support for the LIN
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).
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, reduces code overhead.
Extended Watchdog Timer (WDT): This
enhanced version incorporates a 16-bit prescaler,
allowing a time-out range from 4 ms to over
2 minutes that is stable across operating voltage
and temperature.
1.3 Details on Individual Family
Members
Devices in the PIC18F6310/6410/8310/8410 family are
available in 64-pin (PIC18F6310/8310) and 80-pin
(PIC18F6410/8410) packages. Block diagrams for the
two groups are shown in Figure 1-1 and Figure 1-2,
respectively.
The devices are differentiated from each other in three
ways:
1. Flash Program Memory: 8 Kbytes in PIC18FX310
devices, 16 Kbytes in PIC18FX410 devices.
2. I/O Ports: 7 bidirectional ports on 64-pin
devices, 9 bidirectional ports on 80-pin devices.
3. External Memory Interface: present on 80-pin
devices only.
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.
Like all Microchip PIC18 devices, members of the
PIC18F6310/6410/8310/8410 family are available as
both standard and low-voltage devices. Standard
devices with Flash memory, designated with an “F” in
the part number (such as PIC18F6310), accommodate
an operating VDD range of 4.2V to 5.5V. Low-voltage
parts, designated by “LF” (such as PIC18LF6410),
function over an extended VDD range of 2.0V to 5.5V.
