Notes on QzROM
1. Note on 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.
2. Precautions Regarding Overvoltage
Make sure that voltage exceeding the VCC pin voltage is not
applied to other pins. In particular, ensure that the state indicated
by bold lines in Figure below does not occur for pin CNVSS (VPP
power source pin for QzROM) during power-on or power-off.
Otherwise the contents of QzROM could be rewritten.
Fig. 58 Timing Diagram (bold-lined periods are applicable)
3. QzROM Writing Orders
When ordering the QzROM product shipped after writing,
submit the mask file (extension: .mask) which is made by the
mask file converter MM.
Be sure to set the ROM option (“MASK option” written in the
mask file converter) setup when making the mask file by using
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
regardless of the presence or absence of a protect. When data
other than “FF16” is set, we may ask that the ROM data be
submitted again.
* ROM option data: mask option noted in MM
4. 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
specification 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) 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 1.8 V (shaded portion), so particular care should be
exercised regarding overvoltage.
1.8V
