FR60Lite MB91270/280 Series

MB91F272/F272S/V280

■ DESCRIPTION

The MB91270/280 series is single chip microcontroller that builds various I/O resources and the bus control mechanisms into by using 32-bit efficient RISC CPU for the built-in control being demanded for CPU processing high performance/high-speed. Because the vast address space that 32-bit CPU accesses is supported, the external bus access is basically. To speed up CPU instruction execution, MB91270/280 has built-in RAM of 16 Kbytes (for data) .

It is best specification for the built-in usage in which efficient CPU processing power such as the digital video camera, navigation systems, and DVD players is demanded.

The MB91270/280 series power-up the bus access based on FR30/40 family CPU, and is FR60 Lite family corresponding to use at high speed.

■ HANDLING DEVICES

• Preventing Latch-up

Latch-up may occur in a CMOS IC if a voltage greater than VCC or less than VSS is applied to an input or output pin or if an above-rating voltage is applied between VCC pin and VSS pin. A latch-up, if it occurs, significantly increases the power supply current and may cause thermal destruction of an element. When you use a CMOS IC, do not exceed the maximum rating.

• Treatment of Unused Pins

Do not leave an unused input pin open, since it may cause a malfunction. Handle by, for example, using a pullup or pull-down resistor.

• About Power Supply Pins

In products with multiple VCC or VSS pins, the pins of the same potential are internally connected in the device to avoid abnormal operations including latch-up. However, you must connect the pins to external power supply and a ground line to lower the electro-magnetic emission level, to prevent abnormal operation of strobe signals caused by the rise in the ground level, and to conform to the total output current rating.

Moreover, connect the current supply source with the VCC and VSS pins of this device at the low impedance.

It is also advisable to connect a ceramic bypass capacitor of approximately 0.1 F between VCC and VSS near this device.

• About Crystal Oscillator Circuit

Noise near the X0, X1, X0A and X1A pins may cause the device to malfunction. Design the printed circuit board so that X0, X1, X0A and X1A the crystal oscillator (or ceramic oscillator), and the bypass capacitor to ground are located as close to the device as possible.

It is strongly recommended to design the PC board artwork with the X0, X1, X0A and X1A pins surrounded by ground plane because stable operation can be expected with such a layout.

Please ask the crystal maker to evaluate the oscillational characteristics of the crystal and this device.

• Notes on Using External Clock

When external clock is selected, supply it to X0 pin generally, and simultaneously the opposite phase clock to X0 must be supplied to X1 pin. However, in this case the stop mode (oscillation stop mode) must not be used. (This is because the X1 pin stops at High level output in STOP mode.)

Using an external clock (normal)

X0

X1

Note : The STOP mode (oscillation stop mode) cannot be used.

• Notes when using no sub-clock

Use a single-clock model if not using the sub-clock.

25

MB91270/280 Series

Always connect a resonator of 100 kHz or less on dual clock models.

• Treatment of N.C. or OPEN pins

Pins marked as N.C. and OPEN must be left open - circuit.

• About Mode pins (MD0 to MD2)

These pins should be connected directly to VCC or VSS. To prevent the device erroneously switching to test mode due to noise, design the printed circuit board such that the distance between the mode pins and VCC or VSS is as short as possible and the connection impedance is low.

• Operation at start-up

The INITX pin must be held at the “L”level when turning on the power.

• Source oscillation input at power on

When turning the power on, maintain clock input until the device is released from the oscillation stabilization wait state.

• Caution on Operations during PLL Clock Mode

Even if the oscillator comes off or the clock input stops with the PLL clock selected for this microcontroller, the microcontroller may continue to operate at the free-running frequency of the PLL’s internal self-oscillating oscillator circuit.

Performance of this operation, however, cannot be guaranteed.

• External bus setting

This device is guaranteed for use with a 16 MHz external bus.

If the base clock is set to 32 MHz with DIVR1 (external bus base clock division setting register) set to its initial value, the external bus also operates at 32 MHz. When changing the base clock, first set the external bus so that it will not exceed 16 MHz.

• Pull-up control

The AC characteristics cannot be guaranteed if pull-up resistors are used for pins used as external bus pins.
