SNC12010

The SNC12010 is a one-channel voice synthesizer IC with Push-Pull direct dnve circuit. It built-in a 4-bit tiny controller with three A-bit. I/O ports. By programming through the tiny controller in 5NC12010, user's varied applications including voice section combination, key trigger arrangement, output control, and other logic functions can be easily implemented.

The features of SNC12010 can be summarized as (1)single power supply 2.4V - 5.5V; (2)10 seconds voice capacity are provided (@6KHZ sample rate); (3)built in a 4-bit tiny controller; (4)I/O Port: three 4-bit I/O ports PI, P2 and P3 are provided, the dnvinglsink current of P3.2 & P3.3 is up to 8mA/16mA, the IO plns P3.3 can bs modulated with 35.5Khz carry signal to implement IR; (5)function.; (6)64*4 bits RAM are provided; (7)maximum 16K program ROM is provided; (8)32K*10 shared ROM for voice data and program; (9)readable ROM code data; (10)built in one channel speech synthesizer; (11)adaptive playing speed from 2.5k-20kHz is provided; (12)built in an 8-level volume control push-rill direct drive circuit output, directly; (13)connected to Speaker for wound output; (14)system dock: 2MHz; (15)event mark function supported; (16)low power reset; (17)watch dog timer supported.

The absolute maximum ratings of SNC12010 are (1)supply voltage VDD-V: -0.3 to 6.0V; (2)input voltage VIN: VSS-0.3 to VDD+0.3V; (3)operating temperature TOP: 0 to 55.0°C; (4)storage temperature TSTG: -55.0 to 125.0°C.
