Latch-up may increase the power supply current drastically, causing thermal damage to the device. For the same reason, care must also be taken in not allowing the analog power-supply voltage (AVCC, AVRH) to exceed the digital power-supply voltage. (2) Handling unused pins Leaving unused input pins open may result in misbehavior or latch up and possible permanent damage of the device. Therefor they must be pulled up or pulled down through resistors. In this case those resistors should be more than 2 kΩ. Unused bi-directional pins should be set to the output state and can be left open, or the input state with the above described connection. (3) Using external clock To use external clock, drive X0 pin only and leave X1 pin unconnected. Below is a diagram of how to use external clock. MB90435 Series X0 Open X1 (4) Use of the sub-clock Use one clock system parts when the sub-clock is not used. In that case, pull-down the pin X0A and leave the pin X1A open. When using two clock system parts, a 32 kHz oscillator has to be connected to the X0A and X1A pins. (5) Power supply pins (VCC/VSS) In products with multiple VCC or VSS pins, the pins of a same potential are internally connected in the device to avoid abnormal operations including latch-up. However you must connect the pins to an external power 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 current rating. Make sure to connect VCC and VSS pins via the lowest impedance to power lines. It is recommended to provide a bypass capacitor of around 0.1 µF between VCC and VSS pins near the device. VCC VSS VCC VSS VCC MB90435 Series VSS VCC VSS VSS VCC 16 DS07-13727-2E MB90435 Series (6) Pull-up/down resistors The MB90435 Series does not support internal pull-up/down resistors (except Port0 − Port3 : pull-up resistors) . Use external components where needed. (7) Crystal Oscillator Circuit Noises around X0 or X1 pins may be possible causes of abnormal operations. Make sure to provide bypass capacitors via the shortest distances from X0, X1 pins, crystal oscillator (or ceramic resonator) and ground lines, and make sure, to the utmost effort, that lines of oscillation circuits do not cross the lines of other circuits. It is highly recommended to provide a printed circuit board artwork surrounding X0 and X1 pins with a ground area for stabilizing the operation. (8) Turning-on Sequence of Power Supply to A/D Converter and Analog Inputs Make sure to turn on the A/D converter power supply (AVCC, AVRH, AVRL) and analog inputs (AN0 to AN7) after turning-on the digital power supply (VCC) . Turn-off the digital power after turning off the A/D converter supply and analog inputs. In this case, make sure that the voltage does not exceed AVRH or AVCC (turning on/off the analog and digital power supplies simultaneously is acceptable) . (9) Connection of Unused Pins of A/D Converter Connect unused pins of A/D converter to AVCC = VCC, AVSS = AVRH = VSS. (10) N.C. Pin The N.C. (internally connected) pin must be opened for use. (11) Notes on Energization To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at 50 µs or more (0.2 V to 2.7 V) . (12) Initialization In the device, there are internal registers which are initialized only by a power-on reset. To initialize these registers, please turn on the power again. (13) Directions of “DIV A, Ri” and “DIVW A, RWi” instructions In the Signed multiplication and division instructions (“DIV A, Ri” and “DIVW A, RWi”) , the value of the corresponding bank register (DTB, ADB, USB, SSB) is set in “00H”. If the values of the corresponding bank registers (DTB, ADB, USB, SSB) are set to other than “00H”, the remainder by the execution result of the instruction is not stored in the register of the instruction operand. (14) Using REALOS The use of EI2OS is not possible with the REALOS real time operating system. (15) Caution on Operations during PLL Clock Mode If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even when there is no external oscillator or external clock input is stopped. Performance of this operation, however, cannot be guaranteed.

A stop request is available. Notes : • N/A : The interrupt request flag is not cleared by the EI2OS interrupt clear signal. • For a peripheral module with two interrupt causes for a single interrupt number, both interrupt request flags are cleared by the EI2OS interrupt clear signal. • At the end of EI2OS, the EI2OS clear signal will be asserted for all the interrupt flags assigned to the same interrupt number. If one interrupt flag starts the EI2OS and in the meantime another interrupt flag is set by a hardware event, the later event is lost because the flag is cleared by the EI2OS clear signal caused by the first event. So it is recommended not to use the EI2OS for this interrupt number. • If EI2OS is enabled, EI2OS is initiated when one of the two interrupt signals in the same interrupt control register (ICR) is asserted. This means that different interrupt sources share the same EI2OS Descriptor which should be unique for each interrupt source. For this reason, when one interrupt source uses the EI2OS, the other interrupt should be disabled. DS07-13727-2E 27 MB90435 Series ■ ELECTRICAL CHARACTERISTICS 1.

Also, AVRH, AVRL should not exceed AVCC, and AVRL does not exceed AVRH. *2 : VI and VO should not exceed VCC + 0.3 V. VI should not exceed the specified ratings. However if the maximum current to/from an input is limited by some means with external components, the ICLAMP rating supercedes the VI rating. *3 : The maximum output current is a peak value for a corresponding pin. *4 : Average output current is an average current value observed for a 100 ms period for a corresponding pin. *5 : Total average current is an average current value observed for a 100 ms period for all corresponding pins. *6 : • Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P60 to P67, P70 to P77, P80 to P87, P90 to P97, PA0 • Use within recommended operating conditions. • Use at DC voltage (current) . • The +B signal should always be applied with a limiting resistance placed between the +B signal and the microcontroller. • The value of the limiting resistance should be set so that when the +B signal is applied the input current to the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods. • Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input potential may pass through the protective diode and increase the potential at the VCC pin, and this may affect other devices. • Note that if a +B signal is input when the microcontroller current is off (not fixed at 0 V) , the power supply is provided from the pins, so that incomplete operation may result. • Note that if the +B input is applied during power-on, the power supply is provided from the pins and the resulting supply voltage may not be sufficient to operate the power-on result. (Continued) 28 DS07-13727-2E MB90435 Series (Continued) • Care must be taken not to leave the +B input pin open. • Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input pins, etc.) cannot accept +B signal input. • Sample recommended circuits : • Input/Output Equivalent circuits Protective diode VCC +B input (0 V to 16 V) Limiting resistance P-ch N-ch R Note : Average output current = operating current × operating efficiency WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings. DS07-13727-2E 29 MB90435 Series 2.

AC characteristics. The VCC Capacitor should be greater than this capacitor. WARNING: The recommended operating conditions are required in order to ensure the normal operation of the semiconductor device. All of the device's electrical characteristics are warranted when the device is operated within these ranges. Always use semiconductor devices within their recommended operating condition ranges. Operation outside these ranges may adversely affect reliability and could result in device failure. No warranty is made with respect to uses, operating conditions, or combinations not represented on the data sheet. Users considering application outside the listed conditions are advised to contact their representatives beforehand. • C Pin Connection Diagram C CS 30 DS07-13727-2E MB90435 Series 3.
