μ PD65881GB-P01
μPD71054-Compliant Programmable Timer/Counter Gate Array
Following the phase-out of its popular μ PD71054 standard programmable timer/counter, NEC Electronics is now
offering the μ PD65881GB-01 programmable timer/counter gate array, a functional and low-cost substitute for the
μ PD71054.
To verify the applicability of the μ PD65881GB-01 gate array as a replacement for the μ PD71054, you must first
test an equivalent prototype in the system being developed. If the in-system test is deemed successful, you may then
proceed to purchase mass production versions of the product.
DESCRIPTION
The μ PD65881GB-P01 incorporates an NA54A IP macro in a CMOS-N5 gate array. Internal block functions and
commands are the same as those of the μ PD71054. Differences between the two products are listed below. Before
adopting this product, carefully read the disclaimer below and the caution in section 3 (CAUTIONS WHEN
CONSIDERING ADOPTION OF THIS PRODUCT).
