MPLAB Programmer Support
PRO MATE
PICSTART
Microchip offers two levels of device programmer support. For most bench setups the PICSTART
Plus is sufficient. When true system qualification is done, the PRO MATE II should be the mini-
mum used, due to the validation of program memory at V
ability
The PRO MATE II Universal Programmer is a full-featured programmer capable of operating in
stand-alone mode as well as PC-hosted mode. PRO MATE II operates under MPLAB or as a
DOS command driven program.
The PRO MATE II has programmable V
memory at V
sages, keys to enter commands and a modular detachable socket assembly to support various
package types. In stand-alone mode the PRO MATE II can read, verify or program Baseline,
Mid-Range, and High End devices. It can also set configuration and code-protect bits in this
mode. The PRO MATE II programmer also supports Microchip’s Serial EEPROM and K
Security devices.
A separate In-Circuit Serial Programming (ICSP) module is available for volume programming in
a manufacturing environment. See the Programming module documentation for specific applica-
tion requirements.
The PICSTART Plus programmer is an easy-to-use, low-cost prototype programmer. It connects
to the PC via one of the COM (RS-232) ports. MPLAB Integrated Development Environment soft-
ware makes using the programmer simple and efficient. PICSTART Plus is not recommended for
production programming, since it does not do program memory verification at V
V
PICSTART Plus supports all Baseline, Mid-Range, and High End devices. For devices with up
more than 40 pins an adapter socket is required. DIP packages are the form factor that are
directly supported. Other package types may be supported with adapter sockets.
