32-/16-BIT SINGLE-CHIP MICROCONTROLLERS
The µPD703037A, 703037AY, 70F3037A, and 70F3037AY (V850/SB2) are 32-/16-bit single-chip microcontrollers
of the V850 FamilyTM for AV equipment. 32-bit CPU, ROM, RAM, timer/counters, serial interfaces, A/D converter,
DMA controller, and so on are integrated on a single chip.
The µPD70F3037A and 70F3037AY have flash memory in place of the internal mask ROM of the µPD703037A
and 703037AY. Because flash memory allows the program to be written and erased electrically with the device
mounted on the board, these products are ideal for the evaluation stages of system development, small-scale
production, and rapid development of new products.
The µPD703034A, 703034AY, 703035A, 703035AY, 70F3035A, and 70F3035AY with different ROM/RAM
capacity are also available.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.

There are differences in noise immunity and noise radiation between the flash memory and
mask ROM versions. When pre-producing an application set with the flash memory version
and then mass-producing it with the mask ROM version, be sure to conduct sufficient
evaluations for the commercial samples (not engineering samples) of the mask ROM
version.
2. When replacing the flash memory versions with mask ROM versions, write the same code
in the empty area of the internal ROM.

3. PROGRAMMING FLASH MEMORY (µPD70F3037A, 70F3037AY ONLY)
There are the following two methods for writing a program to the flash memory.
(1) On-board programming
Write a program to the flash memory using a dedicated flash programmer after the µPD70F3037A and
70F3037AY have been mounted on the target board. Also mount a connector, etc. on the target board to
communicate with the dedicated flash programmer.
(2) Off-board programming
Write a program using a dedicated adapter before the µPD70F3037A and 70F3037AY have been mounted on
the target board.
3.1 Selecting Communication Mode
To write to the flash memory, use a dedicated flash programmer and serial communication. Select a serial
communication mode from those listed in Table 3-1 in the format shown in Figure 3-1. Each communication mode is
selected by the number of VPP pulses shown in Table 3-1.

Cautions
1. Do not directly connect the output (or I/O) pins of IC products to each other, or to VDD, VCC,
and GND. Open-drain pins or open-collector pins, however, can be directly connected to
each other. Direct connection of the output pins between an IC product and an external
circuit is possible, if the output pins can be set to the high-impedance state and the output
timing of the external circuit is designed to avoid output conflict.
2. Product quality may suffer if the absolute maximum rating is exceeded even momentarily for
any parameter. That is, the absolute maximum ratings are rated values at which the product
is on the verge of suffering physical damage, and therefore the product must be used under
conditions that ensure that the absolute maximum ratings are not exceeded.
The ratings and conditions indicated for DC characteristics and AC characteristics represent
the quality assurance range during normal operation.

2. When using the main system clock oscillator, wire as follows in the area enclosed by the
broken lines in the above figure to avoid an adverse effect from wiring capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the other signal lines.
• Do not route the wiring near a signal line through which a high fluctuating current
flows.
• Always make the ground point of the oscillator capacitor the same potential as VSS.
• Do not ground the capacitor to a ground pattern through which a high current flows.
• Do not fetch signals from the oscillator.
3. Ensure that the duty ratio of oscillation waveform is not greater than 5.5:4.5.
4. Sufficiently evaluate the matching between the µPD703037A, 703037AY, 70F3037A,
70F3037AY and the resonator.

Notes 1. At the start condition, the first clock pulse is generated after the hold time.
2. The system requires a minimum of 300 ns hold time internally for the SDAn signal (at VIHmin.. of SCLn
signal) in order to occupy the undefined area at the falling edge of SCLn.
3. If the system does not extend the SCLn signal low hold time (tLOW), only the maximum data hold time
(tHD:DAT) needs to be satisfied.

4. The high-speed mode I C bus can be used in the normal-mode I C bus system. In this case, set the
high-speed mode I2C bus so that it meets the following conditions.
• If the system does not extend the SCLn signal low state hold time:
tHD:DAT ≥ 250 ns
• If the system extends the SCLn signal low state hold time:
Transmit the following data bit to the SDAn line prior to the SCLn line release (tRmax. + tSU:DAT =
1,000 + 250 = 1,250 ns: Normal mode I2C bus specification).

Cautions 1. Be sure to start inputting supply voltage (VDD) when RESET = VSS = EVSS = BVSS = 0 V
(the above state), and make RESET high level after the tREG period has elapsed.
2. If supply voltage (BVDD or EVDD) is input before the tREG period has elapsed following the
input of supply voltage (VDD), data may be driven from the pins until the tREG period has
elapsed because the I/O buffer power supply was turned on while the circuit was in an
undefined state. To avoid this situation, it is recommended to input supply voltage
(BVDD or EVDD) after the tREG period has elapsed following the input of supply voltage
(VDD).

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 V DD 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.
