1 Page NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity
as much as possible, and quickly dissipate it once, when it has occurred. Environmental control
must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using
insulators that easily build static electricity. Semiconductor devices must be stored and transported
in an anti-static container, static shielding bag or conductive material. All test and measurement
tools including work bench and floor should be grounded. The operator should be grounded using
wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need
to be taken for PW boards with semiconductor devices on it.
2 HANDLING OF UNUSED INPUT PINS FOR CMOS
Note:
No connection for CMOS device inputs can be cause of malfunction. If no connection is provided
to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels
of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused
pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of
being an output pin. All handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3 STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production process of MOS
does not define the initial operation status of the device. Immediately after the power source is
turned ON, the devices with reset function have not yet been initialized. Hence, power-on does
not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the
reset signal is received. Reset operation must be executed immediately after power-on for devices
having reset function.

Readers
This manual is intended for users who wish to understand the functions of the V850/SF1 and design
application systems using the V850/SF1.
The target devices are shown below.
• Standard products: µPD703075AY, 703076AY, 703078AY, 703078Y, 703079AY, 703079Y, 70F3079AY,
70F3079Y
• Special products: µPD703075AY(A), 703076AY(A), 703078AY(A), 703079AY(A), 70F3079AY(A)
Purpose
This manual is intended to give users an understanding of the hardware functions described in the
Organization below.
Organization The V850/SF1 User’s Manual is divided into two parts: hardware (this manual) and architecture (V850
Series Architecture User’s Manual).
Hardware
• Pin functions
• CPU function
• Internal peripheral functions
• Flash memory programming
• FCAN controller
• Electrical specifications
Architecture
• Data types
• Register set
• Instruction format and instruction set
• Interrupts and exceptions
• Pipeline operation
How to Read This Manual
It is assumed that the reader of this manual has general knowledge in the fields of
electrical engineering, logic circuits, and microcontrollers.
Cautions 1. The application examples in this manual apply to “standard” quality
grade products for general electronic systems. When using an
example in this manual for an application that requires a “special”
quality grade product, thoroughly evaluate the component and circuit
to be actually used to see if they satisfy the special quality grade.
2. When using this manual as a manual for a special grade product,
read the part numbers as follows.
µPD703075AY → µPD703075AY(A)
µPD703076AY → µPD703076AY(A)
µPD703078AY → µPD703078AY(A)
µPD703079AY → µPD703079AY(A)
µPD70F3079AY → µPD70F3079AY(A)
