Pay attention to the following points: • The MB90V495G has no built-in ROM. However, a special-purpose development tool allows the operations as those of one with built-in ROM. ROM capacity depends on settings on a development tool. • On MB90V495G, an image from FF4000H to FFFFFFH is viewed on 00 bank and an image of FE0000H to FF3FFFH is viewed only on FE bank and FF bank. (Modified on settings of a development tool.) • On MB90F455 (S) /F456 (S) /F457 (S) , MB90455 (S) /456 (S) /457 (S) , an image from FF4000H to FFFFFFH is viewed on 00 bank and an image of FE0000H to FF3FFFH is viewed only on FF bank. 6 DS07-13728-5E MB90455 Series ■ PIN ASIGNMENT (TOP VIEW) AVSS X1A/P36* X0A/P35* P33 P32 P31 P30 P44 P43 P42/SOT1 P41/SCK1 P40/SIN1 AVCC AVR P50/AN0 P51/AN1 P52/AN2 P53/AN3 P54/AN4 P55/AN5 P56/AN6 P57/AN7 P37/ADTG P20/TIN0 1 2 3 4 5 6 7 8 9 10 11 12 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 * : MB90F455/F456/F457, MB90455/456/457 : X1A, X0A MB90F455S/F456S/F457S, MB90455S/456S/457S : P36, P35 DS07-13728-5E P21/TOT0 P22/TIN1 P23/TOT1 P24/INT4 P25/INT5 P26/INT6 P27/INT7 MD2 MD1 MD0 RST VCC 13 14 15 16 17 18 19 20 21 22 23 24 P17/PPG3 P16/PPG2 P15/PPG1 P14/PPG0 P13/IN3 P12/IN2 P11/IN1 P10/IN0 X1 X0 C VSS (FPT-48P-M26) 7 MB90455 Series ■ PIN DESCRIPTION Pin No. 1 2 3 to 10 Pin name AVcc AVR P50 to P57 AN0 to AN7 P37 11 ADTG P20 12 TIN0 P21 13 TOT0 P22 14 TIN1 P23 15 TOT1 P24 to P27 16 to 19 20 21 22 23 24 25 26 27 28 29 to 32 INT4 to INT7 MD2 MD1 MD0 RST Vcc Vss C X0 X1 P10 to P13 IN0 to IN3 D D F C C B ⎯ ⎯ ⎯ A A D D D D D E Circuit format ⎯ ⎯ Description Vcc power input pin for A/D converter Power (Vref+) input pin for A/D converter.

Latch-up may also occur when a voltage exceeding maximum rating is applied across Vcc and Vss. • Latch-up causes drastic increase of power current, which may lead to destruction of elements by heat. Extreme caution must be taken not to exceed maximum rating. • When turning on and off analog power source, take extra care not to apply an analog power voltages (AVcc and AVR) and analog input voltage that are higher than digital power voltage (Vcc). • Handling unused pins • Leaving unused input pins open may cause permanent destruction by malfunction or latch-up. Apply pull-up or pull-down process to the unused pins using resistors of 2 kΩ or higher. Leave unused input/output pins open under output status, or process as input pins if they are under input status. • Using external clock • When using an external clock, drive only X0 pin and leave X1 pin open. An example of using an external clock is shown below. Using external clock X0 Open X1 MB90455 series • Notes when using no sub clock • If an oscillator is not connected to X0A and X1A pin, apply pull-down resistor to X0A pin and leave X1A pin open. • About power supply pins • If two ore more Vcc and Vss exist, the pins that should be at the same potential are connected to each other inside the device. For reducing unwanted emissions and preventing malfunction of strobe signals caused by increase of ground level, however, be sure to connect the Vcc and Vss pins to the power source and the ground externally. • Pay attention to connect a power supply to Vcc and Vss of MB90455 series device in a lowest-possible impedance. • Near pins of MB90455 series device, connecting a bypass capacitor is recommended at 0.1 μF across Vcc and Vss. • Crystal oscillator circuit • Noises around X0 and X1 pins cause malfunctions on a MB90455 series device. Design a print circuit so that X0 and X1 pins, an crystal oscillator (or a ceramic oscillator), and bypass capacitor to the ground become as close as possible to each other. Furthermore, avoid wires to X0 and X1 pins crossing each other as much as possible. • Print circuit designing that surrounds X0 and X1 pins with grounding wires, which ensures stable operation, is strongly recommended. 12 DS07-13728-5E MB90455 Series • 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. • Sequence of turning on power of A/D converter and applying analog input • Be sure to turn on digital power (Vcc) before applying signals to the A/D converter and applying analog input signals (AN0 to AN7 pins). • Be sure to turn off the power of A/D converter and analog input before turning off the digital power source. • Be sure not to apply AVR exceeding AVcc when turning on and off. (No problems occur if analog and digital power is turned on and off simultaneously.) • Handling pins when A/D converter is not used • If the A/D converter is not used, connect the pins under the following conditions: “AVcc=AVR=Vcc,” and “Avss=Vss” • Note on turning on power • For preventing malfunctions on built-in step-down circuit, maintain a minimum of 50 μs of voltage rising time (between 0.2 V and 2.7 V) when turning on the power. • Stabilization of supply voltage • A sudden change in the supply voltage may cause the device to malfunction even within the specified Vcc supply voltage operating range. Therefore, the Vcc supply voltage should be stabilized. For reference, the supply voltage should be controlled so that Vcc ripple variations (peak-to-peak values) at commercial frequencies (50 Hz to 60 Hz) fall below 10% of the standard VCC supply voltage and the coefficient of fluctuation does not exceed 0.1 V/ms at instantaneous power switching.

Note : When internal ROM is operating, F2MC-16LX allows viewing ROM data image on FF bank at upper-level of 00 bank. This function is called “mirroring ROM,” which allows effective use of C compiler small model. F2MC-16LX assigns the same low order 16-bit address to FF bank and 00 bank, which allows referencing table in ROM without specifying “far” using pointer. For example, when accessing to “00C000H”, ROM data at “FFC000H” is accessed actually. However, because ROM area of FF bank exceeds 48 Kbytes, viewing all areas is not possible on 00 bank image. Because ROM data of “FF4000H” to “FFFFFFH” is viewed on “004000H” to “00FFFFH” image, store a ROM data table in area “FF4000H” to “FFFFFFH”.

Watchdog Timer The watchdog timer is a 2-bit counter that uses time-base timer or Watch timer as count clock. If the counter is not cleared within an interval time, CPU is reset. • Watchdog timer functions • The watchdog timer is a timer counter that prevents runaway of a program. Once a watchdog timer is activated, the counter of watchdog timer must always be cleared within a specified time of interval. If specified interval time elapses without clearing the counter of a watchdog timer, CPU resetting occurs. This is the function of a watchdog timer. • The interval time of a watchdog timer is determined by a clock cycle, which is input as a count clock. Watchdog resetting occurs between a minimum time and a maximum time specified. • The output target of a clock source is specified by the watchdog clock selection bit (WTC: WDCS) in the Watch timer control register. • Interval time of a watchdog timer is specified by the time-base timer output selection bit/Watch timer output selection bit (WDTC: WT1, WT0) in the watchdog timer control register.

Notes on A/D Converter Section Use the device with external circuits of the following output impedance for analog inputs: Recommended output impedance of external circuits are: Approx. 3.9 kΩ or lower (4.5 V ≤ AVcc ≤ 5.5 V) (sampling period=2.00 μs at 16-MHz machine clock), Approx. 11 kΩ or lower (4.0 V ≤ AVcc < 4.5 V) (sampling period=8.0 μs at 16-MHz machine clock). If an external capacitor is used, in consideration of the effect by tap capacitance caused by external capacitors and on-chip capacitors, capacitance of the external one is recommended to be several thousand times as high as internal capacitor. If output impedance of an external circuit is too high, a sampling period for an analog voltage may be insufficient. • Analog input circuit model R Analog input Comparator C MB90F455 (S) /F456 (S) /F457 (S) and MB90455 (S) /456 (S) /457 (S) 4.5 V ≤ AVCC ≤ 5.5 V R = 2.35 kΩ, C = 36.4 pF : : 4.0 V ≤ AVCC < 4.5 V R = 16.4 kΩ, C = 36.4 pF : : Note : Use the values in the figure only as a guideline. • About errors As [AVR-AVss] become smaller, values of relative errors grow larger. 8.
