QFP* 5 6 48 1 MQFP*2 5 6 48 X0 X1 Pin name Circuit type A Function Pin for connecting the crystal resonator. X0 and X1 can be directly connected to a crystal oscillator. When the oscillation clock is provided to X0 externally, X1 should be left open. The mode input is used for entering the MPU into the test mode. In user applications, MODE is connected to VSS. Applying a reset pulse to this pin forces the MPU to enter the initial state. RST is active low and drives low state when an internal reset occurs. Reset pulses of the duration less than the minimum pulse width may cause the MCU to enter undefined states. These pins have two functions.

Preventing Latchup Latchup may occur on CMOS ICs if voltage higher than VCC or lower than VSS is applied to input and output pins other than medium- and high-voltage pins or if higher than the voltage which shows on “1. Absolute Maximum Ratings” in section “s Electrical Characteristics” is applied between VCC and VSS. When latchup occurs, power supply current increases rapidly and might thermally damage elements. When using, take great care not to exceed the absolute maximum ratings. Also, take care to prevent the analog power supply (AVCC and AVR) and analog input from exceeding the digital power supply (VCC) when the analog system power supply is turned on and off. 2. Treatment of Unused Input Pins Leaving unused input pins open could cause malfunctions. They should be connected to a pull-up or pull-down resistor. The VINT pin of MB89PV940 and MB89P945 is the only exception. 3. Treatment of Power Supply Pins on Microcontrollers with A/D Converter Connect to be AVCC = VCC and AVSS = VSS even if the A/D converter are not in use. 4. Treatment of N.C. Pins Be sure to leave (internally connected) N.C. pins open. 5. Power Supply Voltage Fluctuations Although VCC power supply voltage is assured to operate within the rated range, a rapid fluctuation of the voltage could cause malfunctions, even if it occurs within the rated range. Stabilizing voltage supplied to the IC is therefore important. As stabilization guidelines, it is recommended to control power so that VCC ripple fluctuations (P-P value) will be less than 10% of the standard VCC value at the commercial frequency (50 to 60 Hz) and the transient fluctuation rate will be less than 0.1 V/ms at the time of a momentary fluctuation such as when power is switched. 6. Note to Noise in the External Reset Pin (RST) If the reset pulse applied to the external reset pin (RST) does not meet the specifications, it may cause malfunctions. Use caution so that the reset pulse less than the specifications will not be fed to the external reset pin (RST). 12 MB89940 Series s PROGRAMMING TO THE EPROM ON THE MB89P945 1.

Notes on Using A/D Converter • Input impedance of the analog input pins The A/D converter used for the MB89940 series contains a sample hold circuit as illustrated below to fetch analog input voltage into the sample hold capacitor for eight instruction cycles after activating A/D conversion. For this reason, if the output impedance of the external circuit for the analog input is high, analog input voltage might not stabilize within the analog input sampling period. Therefore, it is recommended to keep the output impedance of the external circuit low (below 10 kΩ). Note that if the impedance cannot be kept low, it is recommended to connect an external capacitor of about 0.1 µF for the analog input pin. Analog Input Equivalent Circuit Sample hold circuit . C = 33 pF . Analog input pin Comparator If the analog input impedance is higher than 10 kΩ, it is recommended to connect an external capacitor of approx. 0.1 µF. . R = 6 kΩ . Close for 8 instruction cycles after activating A/D conversion. Analog channel selector • Error The smaller the | AVCC – AVSS |, the greater the error would become relatively. 33 MB89940 Series 8.
