Precaution
- When Mask ROM version, One-time PROM version and memory size differ in one group, actual values such
as an electrical characteristics, operation margin, A-D conversion accuracy, noise immunity, and noise
radiation may differ from the ideal values due to the difference in the manufacturing processes.
When these products are used switching, perform system evaluation for each product of every after confirming
product specification.
- This document shows difference, some specifications and standards, not for all.
Be sure to refer to the most current data sheet as for the latest detailed specification and an electrical characteristics.

will depend on each
product of Mask ROM version (Standard version, M version, H version, A version)
and One-time PROM version.
So that the product used for mass production obtains the stabilized operation clock
on the user system and its condition, contact the resonator manufacturer and
select the resonator and oscillation circuit constants.
Be careful especially when
range of voltage and temperature is wide.
We recommend to design the circuit in consideration of the wiring pattern of the
feed-back resistor, the dumping resistor and the load capacity in advance.
We publish the reference-use oscillation circuit parameters in Renesas Technology
home page.
