5 / 12 page ¡ Semiconductor MSM6234 5/12 R1, R2, R3, R4, C1, C2, C3, C4 These are input pins of negative logic to be connected to the keyboard. The standard 2 of 8 keyboard can be used with MSM6234RS as illustrated below. R1 to R4 are the input pins of the row side, while C1 to C4 are the input pins of the column side. All the pins are provided with the pull-up resistor of 20 kW to 150 kW internally. The dual tone is output from the TONE OUT pin, by setting both of a row input and a column input to the ground voltage. The Table 1 (See Note) shows the relation between the nominal frequency and the tone output frequency, while the Table 2 (See Note) shows the input condition of R1 to R4 pins and C1 to C4 pins. • Refer to the Table 1 and Table 2 Table-1 R MSM6234RS R = 20 kW to 150 kW VDD R1 R R2 R R3 R R4 R C4 R C3 R C2 R C1 A B C D 3 6 9 # 2 5 8 0 1 4 7 * ROW COL VSS 2 of 8 keyboard Effective Input Nominal Frequency Tone Output Frequency Accuracy (%) Remarks R1 R2 R3 R4 (ROW) C1 C2 C3 C4 (COLUMN) 697 Hz Low Group High Group 770 Hz 852 Hz 941 Hz 1209 Hz 1336 Hz 1477 Hz 1633 Hz 699.1 Hz 766.2 Hz 847.4 Hz 948.0 Hz 1215.9 Hz 1331.7 Hz 1471.9 Hz 1645.0 Hz +0.30% +0.73% +0.57% +0.74% –0.49% –0.54% –0.32% –0.35% |
