μPD65881GB-P03
Product with functions equivalent to those of the
μPD71055 (parallel interface unit), using the gate array method
The μPD65881GB-P03 has an IP macro (product name: NA55A macro) included in CMOS gate array CMOS-N5,
and is a product with functions equivalent to those achieved by the μPD71055 (programmable timer/counter,
discontinued product).
The internal block functions and commands are the same as those of the μPD71055, so the μPD65881GB-P03
can be used as a substitute for the μPD71055.
This product is designed using the gate array method and has therefore some differences and cautions dependent
on the gate array. Before adopting this product, note the disclaimer below and 3. CAUTIONS WHEN CONSIDERING
ADOPTION OF THIS PRODUCT.
