DESCRIPTION Aplus’ aIVR8511 is a 8-bit MCU based Voice chip. It is fabricated with Standard CMOS process with embedded voice storage memory. It can store 85sec voice message with 4-bit ADPCM compression at 6KHz sampling rate. 8-bit PCM is also available as user selectable option to improve sound quality. There are eleven programmable I/O pins. Key trigger and Parallel CPU trigger mode can be configured according to different application requirement. User selectable triggering and output signal options provide maximum flexibility to various applications. Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct speaker driving output minimize the number of external components. Two levels volume control for PWM speaker direct drive is available. 3 Oct 06, 2009 Integrated Circuits Inc. aIVR8511 PIN CONFIGURATION PIN DESCRIPTIONS Pin Names VOUT1 VOUT2_COUT Description PWM output to drive speaker directly PWM output or COUT DAC output select by programmable option VSS Power Ground OSC Oscillator input VDDA Positive Power Supply VDD Positive Power Supply PB0~PB3 Programmable I/O port B PC0~PC3 Programmable I/O port C PD0~PD2 Programmable I/O port D RSTB Reset pin, Low active Note: PB, PC and PD ports are software programmable I/O pins that can be set to different configurations such as pure input, input with pull-up, input with pull-down and output.

Tr is an NPN transistor with beta larger than 150, e.g. 8050D. 4. Rosc = 610K Ohm with Vdd=3.0V can support sampling rate up to 14KHz. 5. For sampling rate higher than 14KHz, smaller value of Rosc should be used. Bonding Diagrams Note: Substrate must be connected to VSS 8 Oct 06, 2009
