Other Special Features

• Memory Endurance: The Flash cells for program

memory are rated to 100,000 erase/write cycles.

Data retention without refresh is conservatively

estimated to be greater than 40 years.

• Extended Instruction Set: The PIC18F2X1X/

4X1X 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 CCP Module: In PWM mode, this

module provides 1, 2 or 4 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.

• 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 auto-

matic baud rate detection and a 16-bit Baud Rate

Generator for improved resolution. When the

microcontroller is using the internal oscillator

block, the USART 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, reduce 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

Section 25.0 “Electrical Characteristics” for

time-out periods.

Details on Individual Family

Members

Devices in the PIC18F2X1X/4X1X 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 five

ways:

Flash program memory

• 16 Kbytes for PIC18F2410/4410 devices

• 32 Kbytes for PIC18F2510/4510 devices

• 48 Kbytes for PIC18F2515/4515 devices

• 64 Kbytes for PIC18F2610/4610 devices

A/D channels (10 for 28-pin devices, 13 for

40/44-pin devices).

I/O ports (3 bidirectional ports on 28-pin devices,

5 bidirectional ports on 40/44-pin devices).

CCP and Enhanced CCP implementation (28-pin

devices have 2 standard CCP modules; 40/44-pin

devices have one standard CCP module and one

ECCP module).

Parallel Slave Port (present only on 40/44-pin

devices).

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 1-3 and

Table 1-4.

Like all Microchip PIC18 devices, members of the

PIC18F2X1X/4X1X 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 PIC18F2610), accommodate an

operating VDD range of 4.2V to 5.5V. Low-voltage

parts, designated by “LF” (such as PIC18LF2610),

function over an extended VDD range of 2.0V to 5.5V.
