Note
QTOP microcontroller. “QTOP microcontroller” is a general term for a single-chip microcontroller with
on-chip one-time PROM, for which total support is provided by NEC programming service from
programming to marking, screening, and verification.
Please refer to “Quality Grades on NEC Semiconductor Devices” (Document No. C11531E) published by NEC
Corporation to know the specification of quality grade on the devices and its recommended applications.
Caution The EPROM version of the
μ
PD78P4026 does not have a level of reliability intended for volume
production of customers’ equipment, and should only be used for experimental or preproduction
function evaluation.
