NOTES ON QzROM
Product shipped in blank
As for the product shipped in blank, Renesas does not perform the
writing test to user ROM area after the assembly process though
the QzROM writing test is performed enough before the assembly
process. Therefore, a writing error of approx.0.1 % may occur.
Moreover, please note the contact of cables and foreign bodies on
a socket, etc. because a writing environment may cause some
writing errors.
Precautions Regarding Overvoltage
Make sure that voltage exceeding the VCC pin voltage is not ap-
plied to other pins. In particular, ensure that the state indicated by
bold lines in Figure below does not occur for CNVSS pin (VPP
power source pin for QzROM) during power-on or power-off. Oth-
erwise the contents of QzROM could be rewritten.
Data Required For QzROM Writing Orders
The following are necessary when ordering a QzROM product
shipped after writing:
1. QzROM Writing Confirmation Form*
2. Mark Specification Form*
3. ROM data...........Mask file
* For the QzROM writing confirmation form and the mark specifi-
cation form, refer to the “Renesas Technology Corp.” Homepage
(http://www.renesas.com/homepage.jsp).
Note that we cannot deal with special font marking (customer's
trademark etc.) in QzROM microcomputer.
VCC pin voltage
CNVSS pin voltage
“L” input
1.8V
(1) Input voltage to other MCU pins rises before VCC pin voltage.
(2) Input voltage to other MCU pins falls after VCC pin voltage.
Note: The internal circuitry is unstable when VCC is below the minimum voltage
specification of 1.8V (shaded portion), so particular care should be exercised
regarding overvoltage.
Notes On QzROM Writing Orders
When ordering the QzROM product shipped after writing, submit
the mask file (extension: .msk) which is made by the mask file
converter MM.
Be sure to set the ROM option data* setup when making the
mask file by using the mask file converter MM.. The ROM code
protect is specified according to the ROM option data* in the
mask file which is submitted at ordering. Note that the mask file
which has nothing at the ROM option data* or has the data other
than “0016” and “FF16” can not be accepted.
Set “FF16” to the ROM code protect address in ROM data re-
gardless of the presence or absence of a protect. When data
other than “FF16” is set, we may ask that the ROM data be sub-
mitted again.
* ROM option data: mask option noted in MM
