SM1350 series High Tone Quality Melody LSI OVERVIEW The SM1350 series are single-chip high tone quality melody ICs, fabricated using NPC’s Molybdenum- gate CMOS process. Melodies are selected in serial or binary (parallel) mode, up to a maximum of 16 melody blocks. There are 4 sound generators incorporated to produce 4 kinds of output tone controlled by 16-tone data, making these ICs ideal for mechanical clocks and similar applications where high tone quality output is demanded. FEATURES s Basic Functions • 4.0 MHz oscillator frequency • Power-save function - Oscillator stopped when no output - S0 to S3, MODE, LH pull-up resistors open • BTL or A-class outputs • Chattering prevention circuit (STN, STOP, S0 to S3) • 10-bit D/A converter s Sound Generator Functions • DWS (dual wave synthesis) sound generators • 4 simultaneous sounds for 4 tones • G2 to F#7 note range • 16-tone programmable s Melody Functions • Up to 16 programmable melodies (singly or in medleys) • 1024-step length (notes, rests, jumps, end codes) • Level hold/one-shot melody modes • Serial/binary (parallel) select modes • 4.8 to 605.6 tempo range in 127 steps • 12 rhythm values 333 3 • Ties and slurs programmable s Control Signal Outputs • BUSYN signal LOW during melody output • CT signal output for external control s 2.4 to 5.5 V supply voltage s Package • 24-pin SSOP (SM1350×××) s Molybdenum-gate CMOS PINOUT(TOP VIEW) VDD S0 S1 S2 S3 MODE LH STOP STN BUSYN CT ICN 1 12 24 XT XTN TO T3N T2N T1N MSBN MSB SP SPN VOL 13 VSS PACKAGE DIMENSIONS 24-pin SSOP (Unit: mm) 10.05 0.20 10.20 0.30 0.7 0.8 0.36 0.10 0.15 +− 00..105 0.50 0.20 0 10 ORDERING INFOMATION Device SM1350 ×××M Package 24pin SSOP NIPPON PRECISION CIRCUITS—1 1 page SM1350 series DC Characteristics VDD = 3 V, Ta = 25 °C, VSS = 0 V, fO = 4.0 MHz Parameter Minimum operating supply voltage1 Maximum operating supply voltage1 Standby current consumption Operating current consumption XT external capacitance XTN external capacitance Clock frequency2 Clock duty cycle2 S0 to S3, MODE, LH, STOP, STN, ICN HIGH-level input voltage S0 to S3, MODE, LH, STOP, STN, ICN LOW-level input voltage S0 to S3, MODE, LH, STOP, STN, ICN HIGH-level input current S0 to S3, MODE, LH, STOP, STN, ICN LOW-level input current BUSYN, CT, TO HIGH-level output current BUSYN, CT,TO LOW-level output current MSB, MSBN HIGH-level output current MSB, MSBN LOW-level output current SP, SPN output current3 Symbol VMIN VMAX ISTBY IDD CG CD fXTI RXTI VIH VIL IIH IIL IOH1 IOL1 IOH2 IOL2 IOH3 Condition No melody output BUSYN, CT, TO, SP, SPN, MSB, MSBN all open min – 5.5 – – – – 3.8 40 VDD − 0.3 VSS VIH = VDD – VIL = VSS – VOH1 = VDD − 0.7 VOL1 = VSS + 0.7 VOH2 = VDD − 0.7 VOL2 = VSS + 0.7 VOH3 = VSS + 0.7 2.0 2.0 3.0 3.0 – Rating typ – – – – 30 30 4.0 50 – – 10 10 – – – – – max 2.4 – 1.0 3.5 – – 4.2 60 VDD VSS + 0.3 20 20 – – – – 4.0 Unit V V µA mA pF pF MHz % V V µA µA mA mA mA mA mA 1.Supply voltage ratings shown are with oscillator running and all functions operating normally. 2.Clock frequency and duty cycle are ratings for the clock input on pin XT. 3.Output current when 20 kΩ volume control resistor is connected to VOL, and all D/A converter bits ON, measured using the circuit of the next page.

Level hold mode (binary select) with “Select change retrigger [No]” mask option If the “Select change retrigger [Yes]” mask option is leading note when any of the S0 to S3 inputs changes selected, a new melody starts playing from the state.

Level hold mode (binary select) with “Select change retrigger [Yes]” mask option Serial select mode (MODE = HIGH) In serial select mode, the next melody is selected by cycling through the melodies in the order #N → #N+1 … #N−1 → #N when the STN input goes LOW. The number of melodies in the cycle is set by master-slice option. Note that when melody output is stopped using the STOP input, the melody-select counter increments.
