1 / 10 page SM1124 Series NIPPON PRECISION CIRCUITS—1 NIPPON PRECISION CIRCUITS INC. Multimelody IC for Pagers OVERVIEW The SM1124 Series are melody pager multi-melody ICs fabricated in NPC’s Molybdenum-gate CMOS. A maximum of 16 tunes can be stored in programmable ROM, and the Molybdenum-gate CMOS process realizes small-sized packages and low power dissipation. FEATURES s Maximum of 16 tune selections (with up to 512 steps) s Level hold playback mode s External reference clock input. The frequency can be selected from the following 12 settings. • Playback frequency of each song varies (8 frequencies) - 32.768 kHz system: 32.768 and 65.536 kHz - 37.5 kHz system: 37.5 and 75.0 kHz - 38.4 kHz system: 38.4 and 76.8 kHz - 48.0 kHz system: 48.0 and 96.0 kHz • Playback frequency of all songs is fixed (4 frequencies) - 32.768 kHz system: 131.072 kHz - 37.5 kHz system: 150.0 kHz - 38.4 kHz system: 153.6 kHz - 48.0 kHz system: 192.0 kHz s 2-pin serial data tune selection s Power save function s External clock gating in non-play mode. s 2.4 to 3.6 V supply voltage s 8-pin plastic SOP package s Molybdenum-gate CMOS process PINOUT 8-pin SOP PACKAGE DIMENSIONS Unit: mm CLK SI SC ST VSS VDD MTO TEST 1 4 5 8 0.4 0.1 1.27 0.4 0.2 010 5.2 0.3 0.15 + 0.10 − 0.05 0.695TYP |
