DESCRIPTION
The MB89160 series is a line of the general-purpose, single-chip microcontrollers. In addition to a compact
instruction set, the microcontrollers contain a variety of peripheral functions such as an LCD controller/driver,
an A/D converter, timers, a serial interface, PWM timers, and external interrupts.

DIFFERENCES AMONG PRODUCTS
1. Memory Size
Before evaluating using the piggyback product, verify its differences from the product that will actually be used.
Take particular care on the following points:
• On the MB89161/A and MB89163/A, the upper half of each register bank cannot be used.
• The stack area, etc., is set at the upper limit of the RAM.
2. Current Consumption
• In the case of the MB89PV160, add the current consumed by the EPROM which is connected to the top sock et.
• When operated at low speed, the product with an OTPROM (one-time PROM) or an EPROM will consume
more current than the product with a mask ROM.
However, the current consumption in the sleep/stop modes is the same. (For more information, see section
“ ■ Electrical Characteristics.”)
3. Mask Options
Functions that can be selected as options and how to designate these options vary by the product.
Before using options check section “ ■ Mask Options.”
Take particular care on the following points:
• A pull-up resistor cannot be set for P20 to P27 on the MB89P165.
• A pull-up resistor is not selectable for P40 to P47 and P60 to P67 if they are used as LCD pins.
• Options are fixed on the MB89PV160.

5. Power Supply Voltage Fluctuations
Although V
could cause malfunctions, even if it occurs within the rated range. Stabilizing voltage supplied to the IC is
therefore important. As stabilization guidelines, it is recommended to control power so that V

transient fluctuation rate will be less than 0.1 V/ms at the time of a momentary fluctuation such as when power
is switched.

PROGRAMMING T O THE EPROM ON THE MB89P165
The MB89P165 is an OTPROM version of the MB89160 series.
1. Features
• 32-Kbyte PROM on chip
• Options can be set using the EPROM programmer.
• Equivalency to the MBM27C256A in EPROM mode (when programmed with the EPROM programmer)

3. Programming to the EPROM
In EPROM mode, the MB89P165 functions equivalent to the MBM27C256A. This allows the PROM to be
programmed with a general-purpose EPROM programmer (the electronic signature mode cannot be used) by
using the dedicated socket adapter.

High-temperature aging is recommended as the pre-assembly screening procedure for a product with a blanked
OTPROM microcomputer program.

5. Programming Yield
All bits cannot be programmed at Fujitsu shipping test to a blanked OTPROM microcomputer, due to its nature.
For this reason, a programming yield of 100% cannot be assured at all times.

FPT-80P-M06 ROM-80QF-28DP-8L3
FPT-80P-M11 ROM-80QF2-28DP-8L2
7. Erasure
In order to clear all locations of their programmed contents, it is necessary to expose the internal EPROM to an
ultraviolet light source. A dosage of 10 W -seconds/cm
dosage can be obtained by exposure to an ultraviolet lamp (wavelength of 2537 Angstroms (Å)) with intensity
of 12000 µ W/cm
filters should be removed from the UV light source prior to erasure.
It is important to note that the internal EPROM and similar devices, will erase with light sources having
wavelengths shorter than 4000Å. Although erasure time will be much longer than with UV source at 2537Å,
nevertheless the exposure to fluorescent light and sunlight will eventually erase the internal EPROM, and
exposure to them should be prevented to realize maximum system reliability. If used in such an environment,
the package windows should be covered by an opaque label or substance.
