Benefits
Because you can maintain and upgrade the program in the MN102HF75K/85K
up to and immediately following product release, this version of the device
shortens time-to-market by as much as one month. This device is ideal for appli-
cations in quickly changing markets, since it allows you to revise the microcon-
troller program in an existing product.
B.3
Using the PROM Writer Mode
In this mode, the MN102HF75K allows a PROM writer to program the internal
flash memory as if it was a standalone memory chip. The microcontroller is
inserted into a dedicated adaptor socket, which connects to DATA-I/O's LabSite
PROM writer. When the microcontroller connects to the adaptor socket, it auto-
matically enters PROM writer mode. The adaptor socket ties the microcontroller
pin states to PROM writer mode, and programming occurs without any reference
to the microcontroller pin states.
