ALM BZB BZ PWM1, 2 GND 4.0 FUNCTIONAL DESCRIPTION 4.1 SRAM The 256 x 4 bits index SRAM and 128 x 4 bits data SRAM are 2 separate regions. 4.2 Index ROM The 256 x 8 bits index ROM can be used as a 4-bit mode or an 8-bit mode. 4.3 I/O Ports The IOA port can be selected by software separately as input or output, and with/without internal pull-low and different chattering clocks in order for HALT release/ interrupt trigger to reduce the bounce of key_scan: PH6: 512Hz PH8:128Hz PH10: 32Hz The pull-low of the IOA will be masked off for those pins defined as output pins. The IOA port can be used as a pseudo serial output port. The IOB port can be selected by software separately as input or output. The IOC port can be selected by software separately as input or output, and with/without internal pull-low and different chattering clocks in order for HALT release/ interrupt trigger to reduce the bounce of key_scan. The IOD port can be selected by software separately as input or output. The IOD port can be used as a pseudo serial output port. The initial state of all I/O ports is standard input state and IOA, C have pull-low device. Before setting some pins from input to output, you can execute the output function to ensure their output value. The S ports are input pins that contain pull_low. The L_L_H resistor can be selected by mask option and different chattering clocks in the same manner as the IOA, C ports. 4.4 Resistor-to-Frequency Converter We use an RC oscillation circuit and a 16-bit counter to calculate the relative resistance of temperature and humidity sensor. The diagram is shown as Figure 1. There are two types of methodology for measuring the input frequency: first, set FIN (i.e. CX) as the clock input, using timer 2 as interval control or using software to directly control the interval. Second, if the FIN (CX) frequency is too low, either because of a poor resolution for a fixed interval or a longer interval for better resolution but with a longer read-out rate (for example: 10 seconds per read-out), you can switch the measure mode in order to set FIN (CX) as interval control (it will enable the counter from first FIN rising edge to the next 5/20 MTU429B Revision 3.0 28/Oct/1999 MYSON TECHNOLOGY MTU429B (Preliminary) rising edge, then will generate an interrupt) and use FREQ (internal frequency generator output) as clock input, hence you can count the interval of CX. To measure the resistor value of the temperature and humidity sensor, we must first measure the frequency of Rref, then the frequency of sensor. Here the Fref = K / Rref * CX and Fsensor = K / Rsensor * CX, hence Rsensor = Rref * Freq/ Fsensor. Where K is a coefficient for RC-oscillation and will bw a constant in a short time period.

R to F Converter Diagram 4.5 Key_board Scanning Function SEG11~26 shares the key_board scanning output, the output of the key_board scanning is a P open-drain to VDDO (positive power supply) and all other SEGs and COMs are in Hi-z state during this period. This will minimize the effect of the LCD output. The segment 11-26 also could be used as keyscan output and LCD still could be displayed with only slightly affected. SPK 00b5 b4 b3 b2 b1 b0. b5: 1 will disable key-scan output. b4: 1 will set all keyscan output as high, if b5=0. b3~b0: will set the corresponding segment output as 1, if b5=0 and b4=0. During power on, LCD off, STOP condition. All the common & segment output will be the chips supply power. 4.6 EL-Light Set the ELC and ELP clock and duty cycle by ELC X instruction, then turn on and off the ELC and ELP output by SF X and RF X instruction. With external transistor, diode, inductor and resistor, we can pump the ELpanel to AC 100~250V. While the light is turned on, the ELC will turn on before the ELP, but when the light is turned off, the ELP and ELC will turn off after the next falling edge of the ELC to make sure no voltage is left on the EL- panel. 4.7 Timer The 6-bit programmable timer can select PH3/PH9/PH15/FREQ (timer 2 can also select PH5/PH7/PH11/ PH13 by TM2X instruction) as the clock source. When it underflows, the HALT release signal is generated. 6/20 MTU429B Revision 3.0 28/Oct/1999 MYSON TECHNOLOGY D1 L1 Q1 MTU429B (Preliminary) R1 Q2 ELP R2 EL-plane ELC LIT ELP ELC 4.8 Predivider The predivider is a 15-stage counter that uses PH0 as the clock source. The output of T-F/F is changed when the input signal is changed from H to L. PH11~15 are reset to L when PLC 100H instruction is executed, or power-on or external reset is used. When PH14 is changed from H to L, the HALT release signal is generated. 4.9 Alarm/Frequency/Melody There is an 8-bit programmable counter and an 8-bit envelope control for alarm, frequency or melody output from BZ/BZB. The frequency counter can use software to select 1/2 duty, 1/3 duty or 1/4 duty drive mode. FREQ 1/2 DUTY FREQ 1/3 DUTY FREQ 1/4 DUTY FREQ 4.10 INT Function The INT pin can be selected by mask option as pull-high/pull-low or none, and rising edge/falling edge trigger. 4.11 Watchdog Timer The watchdog timer automatically generates a device reset when it overflows. The interval of overflow is 8/64/ 512 x PH10 (set by mask option). You can use software to enable and disable this function. The watchdog enable flag will be disabled by power-on reset or reset-pin reset condition, but can not be disabled by watchdog reset itself. 4.12 HALT Function The HALT instruction will disable all clocks except the predivider, timer, frequency counter, PWM, EL-light generator and chattering clock to minimize the operating current. 4.13 STOP Function The STOP instruction will disable all clocks to minimize the standby current, so only two external factors (INT, IOA/IOC/S port, keyscan) can release the STOP condition. 7/20 MTU429B Revision 3.0 28/Oct/1999 MYSON TECHNOLOGY 5.0 BSOLUTE MAXIMUM RATINGS at Ta=0 to 70 oC, GND=0V Name Symbol VDD1 VDD2 VDD3 VDD4 Vin Vout1 Vout2 Topq Tstg MTU429B (Preliminary) Range -0.3 to 5.5 -0.3 to 5.5 -0.3 to 8.5 -0.3 to 8.5 -0.3 to VDD 1/2 +0.3 -0.3 to VDD1/2 + 0.3 -0.3 to VDD3 + 0.3 0 to +70 -25 to +125 Unit V V V V V V V o o Maximum Supply Voltage Maximum Input Voltage Maximum Output Voltage Maximum Operating Temperature Maximum Storage Temperature C C 6.0 ALLOWABLE OPERATING CONDITIONS at Ta=0 to 70 oC, GND=0V Name Symb.

bias and 1/4 bias. If 1/2 bias chosen, VDD3 need be connected to VDD2 (VDD3 is equal to VDD2). *2: VDD4 is only used for LCD operating in 1/4 bias. If 1/3 bias chosen, VDD4 need be connected to VDD3 (VDD4 is equal to VDD3). If 1/2 bias chosen, VDD4 need be connected to VDD2 (VDD4 is equal to VDD2). *3: BAK is defined as chip’ internal power supply node, which is used only for internal logic circuitry. s A. Whatever the power mode used, all external VDD# pins must connect a capacitor (0.05uF or 0.1uF) to GND for decoupling power noise using. B. All VDD# pins other than Vsupply are from voltage charge pump, i.e. If no clock, then VDD# pins can not supply out. C. Vsupply is the power supply for Chip and depends on the power mode used, all the input and output pins voltage range follow the Vsupply. 9.2 The capacitor connected between CUP2 and CUP3 is only when MTU429B operating in 1/4 bias. 9.3 Some notes for BCF flag BCF is always set to “High” automatically after Power on, Reset and Stop mode. A. For power saving use, BCF may be set to “Low” which can reduce chip’ current consumption. s B. Ag and Li battery mode applications: After Power on, Reset or release from Stop mode. Need to wait 2 seconds long, then can set BCF to “Low”. C. Larger current load and fast clock: a. BCF should be set to “High” for the case of fast clock or larger current load (such as RFC, ADC, DAC, EL-light and Buzzer output) use. b. After set BCF to “high”, need wait 2 ms long at least, then can enable larger current load. Or after disable Larger current load, need wait 2ms long at least, then can set BCF to “Low” D. Li battery mode applications: Especially for Li battery mode, BCF switching will cause a temporary current surge (or power noise) on BAK. Furthermore if not necessary, don’ switch BCF too often as possible. t E. Improperly use of BCF will cause malfunction to chips. 19/20 MTU429B Revision 3.0 28/Oct/1999 MYSON TECHNOLOGY MTU429B (Preliminary) F. Lower current consumption and reliability: The chip’ reliability will greatly decrease if invalid use BCF, especially for Li-battery mode. Because the s chip’ internal power also switches between VDD1 and VDD2, which also cause a temporary power s noise. 9.4 Input pin Any input pins floating will cause chips in malfunction and large current consumption. 9.5 32.768KHz X’ al oscillator t Always layout the X’al as close the Chips as possible and don’ place any signals across the layout routing. t t Since X’al oscillation circuit consumes current only 0.5uA to 1uA, any power noise will disturb the oscillation. t The proper external capacitors for Xin and Xout are necessary for the accuracy and stability of oscillation. 1/( Cin+Cpcb ) + 1/( Cout+Cpcb ) = 1/CL The Chip’ Xout pin has an internal capacitor around 10~20pf connected to BAK (chip’ internal Node). s s For example Epson’ C-001R 20ppm, CL=12.5pf s Cin = 25pf Cout = 15pf The time accuracy will be around +/- 0.5 second/day Note: The parasitic capacitors of X’al pins in PCB layout need be considered in above calculation. t 9.6 RFC / Event counter / IOA for MTU429B If anyone uses RFC / Event counter function and IOAs in the same application, make sure the pin IOA1 (which is corresponding to CX by mask option) must set as IOA’ output mode by SPA instruction. Or the s signal changes on CX pin may cause halt release or interrupt for IOA’ port. In this case the program couldn’ s t function properly. Myson Technology, Inc. No. 2, Industry E. Rd.
