PIC10(L)F320/322
This document includes the
programming specifications for the
following devices:
1.0 OVERVIEW
The PIC10(L)F320/322 devices are programmed using
In-Circuit Serial Programming™ (ICSP™). This
programming specification applies to the
PIC10(L)F320/322 devices in all packages.
With the exception of memory size and the voltage
regulator, all other aspects of the PIC10(L)F320/322
devices are identical.
1.1 Hardware Requirements
1.1.1 HIGH-VOLTAGE ICSP
PROGRAMMING
In High-Voltage ICSP mode, the device requires 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, the PIC10(L)F320/322
devices can be programmed using a single V
DD 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 the Configuration Word 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.
• PIC10F320 • PIC10LF320
• PIC10F322 • PIC10LF322
Note 1: The High-Voltage ICSP mode is always
available, regardless of the state of the
LVP bit, by applying V
IHH to the MCLR/
V
PP 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.
