B.2 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.
