This document includes the
programming specifications for the
following devices:
1.0 OVERVIEW
The devices can be programmed using either the high-
voltage In-Circuit Serial Programming™ (ICSP™)
method or the low-voltage ICSP™ method.
When using low-voltage ICSP™ programming
(LVP = 1), the ICSPDAT/ICSPCLK functions are
additionally enabled on the RA0/RA1 port pins. This
legacy programming feature provides compatibility
support for existing PIC18F1XK50 designs. For new
designs, using the ICSPDAT/ICSPCLK functions on
the RC0/RC1 port pins is recommended.
For Legacy Programming Support, refer to
Section 4.2.1 “Legacy ICSP Pinout Programming”.
1.1 Hardware Requirements
1.1.1 HIGH-VOLTAGE ICSP
PROGRAMMING
In High-Voltage ICSP™ mode, these devices require
two programmable power supplies: one for V
DD and
one for the MCLR
/VPP pin.
1.1.2 LOW-VOLTAGE ICSP
PROGRAMMING
In Low-Voltage ICSP™ mode, these devices can be
programmed using a single VDD source in the
operating range. The MCLR/VPP pin does not have to
be brought to a different voltage, but can instead be left
at the normal operating voltage.
1.1.2.1 Single-Supply ICSP Programming
The LVP bit in Configuration Word 2 enables single-
supply (low-voltage) ICSP programming. The LVP bit
defaults to a ‘1’ (enabled) from the factory. The LVP bit
may only be programmed to ‘0’ by entering the High-
Voltage ICSP mode, where the MCLR
/VPP pin is raised
to V
IHH. Once the LVP bit is programmed to a ‘0’, only
the High-Voltage ICSP mode is available and only the
High-Voltage ICSP mode can be used to program the
device.
• PIC16F1454 • PIC16LF1454
• PIC16F1455 • PIC16LF1455
• PIC16F1459 • PIC16LF1459
Note 1: The High-Voltage ICSP mode is always
available, regardless of the state of the
LVP bit, by applying VIHH to the MCLR/
VPP pin.
2: While in Low-Voltage ICSP mode, MCLR
is always enabled, regardless of the
MCLRE bit, and the port pin can no
longer be used as a general purpose
input.
