■ DIFFERENCES AMONG PRODUCTS

1. Memory Size

Before evaluating using the OTPROM (one-time PROM) products (also used for evaluation), verify its differences

from the product that will actually be used.

Take particular care on the following point:

• The stack area, etc., is set at the upper limit of the RAM.

2. Current Consumption

When operated at low speed, the product with an OTPROM or an EPROM will consume more current than the

product with a mask ROM.

However, the current consumption in sleep/stop modes is the same.

3. Mask Options

In the MB89P857/W857, no option can be set.

Before using options check section “■ Mask Options.”

Take particular care on the following point:

• A pull-up resistor can be set for P00 to P07, P10 to P17 and P20 to P27 only at single-chip mode.

■ HANDLING DEVICES

1. Preventing Latchup

Latchup may occur on CMOS ICs if voltage higher than VCC or lower than VSS is applied to input and output pins

other than medium- and high-voltage pins or if higher than the voltage which shows on “1. Absolute Maximum

Ratings” in section “■ Electrical Characteristics” is applied between VCC and VSS.

When latchup occurs, power supply current increases rapidly and might thermally damage elements. When

using, take great care not to exceed the absolute maximum ratings.

Also, take care to prevent the analog power supply (AV^CCand AVR) and analog input from exceeding the digital

power supply (VCC) when the analog system power supply is turned on and off.

2. Treatment of Unused Input Pins

Leaving unused input pins open could cause malfunctions. They should be connected to a pull-up or pull-down

resistor.

3. Treatment of Power Supply Pins on Microcontrollers with A/D and D/A Converters

Connect to be AVCC = DAVC = VCC and AVSS = AVR = VSS even if the A/D and D/A converters are not in use.

4. Treatment of N.C. Pin

Be sure to leave (internally connected) N.C. pin open.

5. Power Supply Voltage Fluctuations

Although VCC power supply voltage is assured to operate within the rated range, a rapid fluctuation of the voltage

couldcausemalfunctions, evenifitoccurswithintheratedrange. StabilizingvoltagesuppliedtotheICistherefore

important. As stabilization guidelines, it is recommended to control power so that V^CCripple fluctuations (P-P

value) will be less than 10% of the standard V^CCvalue at the commercial frequency (50 to 60 Hz) and the transient

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

6. Precautions when Using an External Clock

Even when an external clock is used, oscillation stabilization time is required for power-on reset (optional) and

wake-up from stop mode.

■ PROGRAMMING TO THE EPROM ON THE MB89P857/W857

The MB89P857/W857 are an OTPROM version of the MB89850R series.

1. Features

• 32-Kbyte PROM on chip

• Equivalency to the MBM27C256A in EPROM mode (when programmed with the EPROM programmer)

3. Programming to the EPROM

In EPROM mode, the MB89P857/W857 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.

• Programming procedure

(1) Set the EPROM programmer to the MBM27C256A.

(2) Load program data into the EPROM programmer at 0000^Hto 7FFFH (note that addresses 8000H to FFFFH

while operating as a single chip assign to addresses 0000H to 7FFFH in EPROM mode.)

(3) Program to 0000^Hto 7FFFH with the EPROM programmer.

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.

6. 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/cm²is required to completely erase an internal EPROM. This

dosage can be obtained by exposure to an ultraviolet lamp (wavelength of 2537 Angstroms (Å)) with intensity

of 12000 µW/cm²for 15 to 21 minutes. The internal EPROM should be about one inch from the source and all

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 4000 Å. Although erasure time will be much longer than with UV source at 2537 Å,

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.

2. Registers

The F²MC-8L family has two types of registers; dedicated registers in the CPU and general-purpose registers

in the memory. The following dedicated registers are provided:

Program counter (PC):

Accumulator (A):

A 16-bit register for indicating instruction storage positions

A 16-bit temporary register for storing arithmetic operations, etc. When the

instruction is an 8-bit data processing instruction, the lower byte is used.

Temporary accumulator (T): A 16-bit register which performs arithmetic operations with the accumulator

When the instruction is an 8-bit data processing instruction, the lower byte is used.

Index register (IX):

Extra pointer (EP):

Stack pointer (SP):

Program status (PS):

A 16-bit register for index modification

A 16-bit pointer for indicating a memory address

A 16-bit register for indicating a stack area

A 16-bit register for storing a register pointer, a condition code

MB89850R Series

The RP indicates the address of the register bank currently in use. The relationship between the pointer contents

and the actual address is based on the conversion rule illustrated below.

• Rule for Conversion of Actual Addresses of the General-purpose Register Area

The CCR consists of bits indicating the results of arithmetic operations and the contents of transfer data and

bits for control of CPU operations at the time of an interrupt.

H-flag: Set when a carry or a borrow from bit 3 to bit 4 occurs as a result of an arithmetic operation. Cleared

otherwise. This flag is for decimal adjustment instructions.

I-flag: Interrupt is allowed when this flag is set to 1. Interrupt is prohibited when the flag is set to 0. Set to 0

when reset.

IL1, 0: Indicates the level of the interrupt currently allowed. Processes an interrupt only if its request level is

higher than the value indicated by this bit.

N-flag: Set if the MSB is set to 1 as the result of an arithmetic operation. Cleared when the bit is set to 0.

Z-flag: Set when an arithmetic operation results in 0. Cleared otherwise.

V-flag: Set if the complement on 2 overflows as a result of an arithmetic operation. Reset if the overflow does

not occur.

C-flag: Set when a carry or a borrow from bit 7 occurs as a result of an arithmetic operation. Cleared otherwise.

Set to the shift-out value in the case of a shift instruction.

MB89850R Series

The following general-purpose registers are provided:

General-purpose registers: An 8-bit register for storing data

The general-purpose registers are 8 bits and located in the register banks of the memory. One bank contains

eight registers and up to a total of 32 banks can be used on the MB89850R series. The bank currently in use

is indicated by the register bank pointer (RP).

Note: The number of register banks that can be used varies with the RAM size.

Vacancy

Notes: • Do not use vacancies.

• When a read-modify-write instruction (such as bit set) is used to access a write-only register or a register

containing a write-only bit, a bit designated by the instruction will have a predetermined value. However,

a write-only bit included, if any, in bits not defined by the instruction will cause a malfunction. So no access

to the register should be tried with any read-modefy-write instruction.

6. A/D Converter Glossary

• Resolution

Analog changes that are identifiable with the A/D converter

• Linearity error

The deviation of the straight line connecting the zero transition point (“00 0000 0000” ↔ “00 0000 0001”) with

the full-scale transition point (“11 1111 1111” ↔´“11 1111 1110”) from actual conversion characteristics

• Differential linearity error

The deviation of input voltage needed to change the output code by 1 LSB from the theoretical value

• Total error

The total error indicates the difference between the actual value and theoretical value. This error is caused by

the zero transition error, full-scale transition error, linearity error, quantization, and noise.

7. Notes on Using A/D Converter

• Input impedance of the analog input pins

The A/D converter used for the MB89860/850 series contains a sample hold circuit as illustrated below to

fetch analog input voltage into the sample hold capacitor for fifteen instruction cycles after activation A/D

conversion.

For this reason, if the output impedance of the external circuit for the analog input is high, analog input voltage

might not stabilize within the analog input sampling period. Therefore, it is recommended to keep the output

impedance of the external circuit low (below 10 kΩ).

Note that if the impedance connot be kept low, it is recommended to connect an external capacitor of about

0.1 µF for the analog input pin.

• Analog Input Equivalent Circuit

Sample hold circuit

.

C = 64 pF

.

Anlog input pin

Comparator

If the analog input

impedance is higher

than 10 kΩ, it is

recommended to

connect an external

capacitor of approx.

0.1 µF.

.

R = 3 kΩ

.

Close for 15 instruction cycles

after activating A/D conversion.

Analog channel selector

• Error

The smaller the | AVR – AV^SS|, the greater the error would become relatively.
