MSM6052-70GS

The MSM6052-70GS is Tone/Pu|se switchable repertory sialer which are fabricated by OK's low power consumption CMOS silicon gate technology .All of these LSIs can generate either DTMF (Dual Tone Multi frequency) signal or DP(Dial Pulse)signal.

Features of the MSM6052-70GS are:(1)either DTMF signal or DP signal generation.500 digits reperftory memory ; (2)24 telephone numbers which can be recalled by single key operation and additional 30 telephone numbers which can be recalled by 2-digits abbreviated code; (3)mixed dialing,mixed stering(repertory memory); (4)last number redial(32 digits maximum); (5)auto insertion of 4 seconds access pause; (6)pulse rate 10/20 pps pin selectable; (7)make/break ratio 34/66 or 40/60 pin selectable; (8)alarn tone for wrong operations; (9)3.58 MHz for ceramic resonator oscillation circuit on-chip; (10)supply voltage range 2.5V~6V; (11)Low stand-by current 0.2 A maximum.

The absolute maximum ratings of the MSM6052-70GS can be summarized as:(1)supply voltage:-0.3~7V; (2)input voltage:-0.3~Vdd+0.3V; (3)output voltage:-0.3~Vdd+0.3; (4)power dissipation:200max mW; (5)storage temperature:-55~+125.If you want to know more information such as the electrical characteristics about the BF904, please download the datasheet in www.seekic.com or www.chinaicmart.com.
