PIC16F193X/LF193X
This document includes the
programming specifications for the
following devices:
1.0
OVERVIEW
The PIC16F193X and PIC16LF193X devices can be
programmed using either the high-voltage In-Circuit
Serial
Programming
(ICSP)
method
or
the
low-voltage ICSP method.
1.1
Hardware Requirements
1.1.1
HIGH-VOLTAGE ICSP
PROGRAMMING
In High-Voltage ICSP mode, the PIC16F193X and
PIC16LF193X devices require two programmable
power supplies: one for VDD and one for the
MCLR/VPP/RE3 pin.
1.1.2
LOW-VOLTAGE ICSP
PROGRAMMING
In Low-Voltage ICSP mode, the PIC16F193X and
PIC16LF193X devices can be programmed using a
single VDD source in the operating range. The
MCLR/VPP/RE3 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 MCLR/VPP/RE3 pin is
raised to VIHH. 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.
1.2
Pin Utilization
Five pins are needed for ICSP programming. The
pins are listed in Table 1-1.

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/RE3 pin.
2: While in Low-Voltage ICSP mode, MCLR
is always enabled, regardless of the
MCLRE bit, and RE3 pin can no longer be
used as a general purpose input.

Note
1:
In the PIC16F193X/LF193X, the programming high voltage is internally generated. To activate the Program/Verify
mode, high voltage needs to be applied to MCLR input. Since the MCLR is used for a level source, MCLR does not
draw any significant current.
