Manipulation with the programmed device
After selection of desired device for your work, you can insert it into the open ZIF socket (the
lever is up) and close socket (the lever is down). The correct orientation of the programmed
device in ZIF socket is shown on the picture near ZIF socket on the programmer's cover. The
programmed device is necessary to insert into the socket also to remove from the socket
when LED BUSY light off.
Note: Programmer's protection electronics protect the target device and the programmer
itself against either short or long-term power failures and, partly, also against a PC failure.
However, it is not possible to grant the integrity of the target device due to incorrect, user-
selected programming parameters. Target device may be not destroyed by forced interruption
of the control program (reset or switch-off PC), by removing the physical connection to the
programmer, but the content of actually programmed cell may remains undefined. Don't
unplug the target device from the ZIF socket during work with devices (LED BUSY shine).
In-system serial programming by 859
Optimized advanced pindriver deliver programming performance without overshoot or ground
bounce for all device technologies. Pin drivers operate down to 1.8V so you'll be ready to
program the full range of today's advanced low- voltage devices.
The ISP programming solution performs programming verification at the marginal level of
supply voltage, which, obviously, improves programming yield, and guarantees long data
retention.
The ISP programming solution provides also the power supply for the target system.
This ISP programming solution provides very competitive price but excellent hardware design
for reliable programming.
The software provide full information for ISP implementation: Description of ISP connector
pins for currently selected chip, recommended target design around in-circuit programmed
chip and other necessary information.
For general definition, recommendation and direction about ISP see section
Common notes
/ ISP please.
