Pin Assignment 1 (Top View) 64 pin PSDIP Package

Note)

PESEL pin serves to switch the I/O signal of the socket on top of the package from interface with the

evaluator (Eva mode) to interface with EPROM (Piggyback mode).

Setting PESEL pin to H Ievel brings Eva mode to enable the connection with the evaluator. Setting it to

L level brings piggyback mode to enable the mounting of EPROM. For QFP piggyback, it is necessary

only to exchange EVACAP (or EPROM) for EPROM (or EVACAP) and no other special measures are

required.
