2 / 7 page  Integrated Circuits Inc. aIVR8511 Oct 06, 2009 3 FEATURES Standard CMOS process. Embedded EPROM. Embedded 8-bit MCU. 85sec voice duration at 6 KHz sampling with 4-bit ADPCM compression. Combination of voice building blocks to extend playback duration. Table entries are available for voice block combinations. User selectable PCM or ADPCM data compress. Voice Group Trigger Options: Edge / Level; Hold / Un-hold; Retrigger / Non-retrigger. Programmable I/Os, Timer Interrupt and Watch Dog Timer. Built-in oscillator with fixed Rosc, software control sampling frequency 2.2V – 3.6V single power supply and < 5uA low stand-by current. PWM Vout1 and Vout2 drive speaker directly with two levels of volume selection. D/A COUT with ramp-up ramp-down option to drive speaker through an external BJT. 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. |
