PIC12(L)F1612/16(L)F161X Memory Programming Specification

This document includes the programming specifications for the following devices:

• PIC12F1612 • PIC12LF1612

• PIC16F1613 • PIC16LF1613

• PIC16F1614 • PIC16LF1614

• PIC16F1615 • PIC16LF1615

• PIC16F1618 • PIC16LF1618

• PIC16F1619 • PIC16LF1619

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.

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 VDD 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 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.

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.
