Note on Memory
Notes on QzROM
1. Note on Product shipped in blank
2. Overvoltage
Take care not to apply the voltage above the Vcc pin voltage to
other pins. Make sure that the voltage of the CNVSS pin (VPP
power input pin for QzROM) does not change as shown in the
bold-lined periods (Figure 92) when powering on and off. If the
voltage changes as shown, the QzROM contents may be
rewritten.
Fig 92. 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
1.8 V
(1) The input voltage to other MCU pins rises before the VCC pin
voltage rises.
(2) The input voltage to other MCU pins falls before the VCC pin
voltage falls.
Note: If VCC falls below the minimum value 1.8 V (shaded areas),
the internal circuit becomes unstable. Take additional care
to prevent overvoltage.
