Note on A/D Converter
Method to stabilize A/D Converter is described below.
(a) A/D conversion accuracy could be affected for Bus Powered*1
USB devices, while the communicating.
Figure 48 shows the method to stabilize A/D conversion accu-
racy, inserting a capacitor between Vref and VSS.
*1: Power supplied by USB VCC BUS.
(b) It is recommended for A/D accuracy to avoid converting while
USB communication, and use average value of several con-
verted values.
DATA REQUIRED FOR MASK ORDERS
The following are necessary when ordering a mask ROM produc-
tion:
(1) Mask ROM Order Confirmation Form
(2) Mark Specification Form
(3) Data to be written to ROM, in EPROM form
................................... (three identical copies) or one floppy disk
* For the mask ROM confirmation and the mark specifications,
refer to the “Renesas Technology Corp.” Homepage
(http://www.renesas.com).
One Time PROM Version
The CNVss pin is connected to the internal memory circuit block by a
low-ohmic resistance, since it has the multiplexed function to be a
programmable power source pin (VPP pin) as well.
To improve the noise reduction, connect a track between CNVss pin
and Vss pin with 1 to 10 k
resistance.
The mask ROM version track of CNVss pin has no operational inter-
ference even if it is connected via a resistor.
Electric Characteristic Differences Among
Mask ROM and One TIme PROM Version MCUs
There are differences in electric characteristics, operation margin,
noise immunity, and noise radiation among mask ROM and One
Time PROM version MCUs due to the differences in the manufac-
turing processes.
When manufacturing an application system with One Time PROM
version and then switching to use of the mask ROM version, per-
form sufficient evaluations for the commercial samples of the
mask ROM version.
Note on Power Source Voltage
When the power source voltage value of a microcomputer is less
than the value which is indicated as the recommended operating
conditions, the microcomputer does not operate normally and may
perform unstable operation.
In a system where the power source voltage drops slowly when
the power source voltage drops or the power supply is turned off,
reset a microcomputer when the supply voltage is less than the
recommended operating conditions and design a system not to
cause errors to the system by this unstable operation.
