1. Introduction
This application note describes the Atmel
programmer cable communicates serially with Atmel's AT89S/AT89LP microcontrol-
lers and reprograms them in the circuit without removal. For surface-mounted devices,
eliminating this step greatly reduces the possibility of damages caused by inser-
tion/removal of delicate leads, and allows for design changes and software/parameter
updates in the field.
2. Parallel Port Settings
For optimal operation, it is recommended that the user’s PC/laptop parallel port setting
be configured for EPP (Enhanced Parallel Port). This can be done in the BIOS screen
after a boot-up sequence.
For laptops without a parallel port, a USB-to-Parallel converter product such as the
one featured in the following link is recommended:
3. AT89ISP Software
The AT89ISP software is the primary means for performing in-system program-
ming (ISP) of Atmel AT89S/AT89LP devices. It provides an intuitive interface for in-
system programming that can be run from a personal computer. The software will run
under the Windows
has a comprehensive set of features that allows a user to view, program, and erase
data from an Atmel AT89S/AT89LP device. A detailed Adobe
describing the features/functions of the software accompanies it.
4. AT89ISP Cable
In order to use the AT89ISP software, the user will need to have an Atmel AT89ISP
cable. This cable can be purchased directly from Atmel or authorized Atmel represen-
tatives. The ISP cable's pins need to be connected to an AT89S/AT89LP device in the
manner shown in
allel port of the user’s personal computer. The 10-pin female IDC header plugs into a
10-pin male header in the user’s target board. A polarized 10-pin receptacle male
header is highly recommended to avoid an erroneous connector mating. The pinout
shown below represents the target 10-pin male header connector in the user's board
as viewed from the top. Please note that connection of the SS pin (P1.4) is
required for all the AT89LP (single-cycle core) derivatives, but not for the AT89S
derivatives.
