SN67D03B

SN67d03B One Channel Direct Drive Speech Controller INTRODUCTION SN67d03B is a 3 seconds one-channel single chip voice synthesizer IC which contains a PWM Direct Drive Circuit. There are two IO pins (one input, one IO), which can be configured as two trigger pins, or one trigger and one output. By filling a coding form, users’ applications, including section combination, trigger modes, and different output status, can be easily implemented. FEATURES Single power supply 2.4V – 5.5V 3 seconds voice capacity is provided 1-bit input port (P1) and 1-bit I/O port (P2) are provided 16*1 bits RAM are provided Built in a high quality speech synthesizer Two different playing rate, 6KHz and 8KHz. Built in a PWM Direct Drive circuit output BUO1 and BUO2 directly connected to Speaker for sound output System clock: 2MHZ Low Voltage Reset PIN ASSIGNMENT Symbol P1 P2 VDD OSC GND BUO1 BUO2 TEST I/O I I/O I I I O O I www.DataSheet4U.com Function Description Input port I/O port Positive power supply Oscillation component connection pin Negative power supply PWM output 1 PWM output 2 For Sonix test Ver1.0 1 July 12, 2006 SN67d03B One Channel Direct Drive Speech Controller ABSOLUTE MAXIMUM RATINGS Items Supply Voltage Input Voltage Operating Temperature Storage Temperature Symbol VDD-V VIN TOP TSTG Min -0.3 GND-0.3 -20.0 -55.0 Max 6.0 VDD+0.3 70.0 125.0 Unit.
