The GA8130 is a digital ChipCorder® providing single-chip storage and playback of high quality audio.
The device features digital de-compression, comprehensive memory management, flash storage, and integrated audio signal path and Class D speaker driver capable of delivering power of 400mW. This family utilizes flash memory to provide non-volatile audio playback with duration up t o 30 seconds (based on 8kHz/4bit ADPCM compression) for a single-chip audio playback solution.
The GA8130 can be controlled and programmed through an SPI serial interface or operated stand-alone by triggers applied to the device’s six GPIO pins.
The GA8130 requires no external clock sources or components except a s peaker to deliver quality audio prompts or sound effects to enhance user interfaces.
In addition the part can provide non-volatile flash storage in 1Kbyte sectors eliminating the need for additional serial EEPROM/Flash devices.
Compared to previous ChipCorder series, this device provides higher sampling frequencies, improved SNR, lower power, fast programming time and integrated program verification
Duration
o GA8130 – 30 seconds based on 8kHz/4bit ADPCM in 1Mbit of flash storage (128KB)
• Audio Management
o Store pre-recorded audio (Voice Prompts) using high quality digital compression
o Use simple index based command for playback – no address needed.
o Execute pre-programmed macro scripts (Voice Macros) designed to control the configuration
of the device and playback Voice Prompts sequences.
• Control
o Serial SPI interface for microprocessor control and programming.
o Stand-alone control where customized Voice Macro scripts are assigned to GPIO trigger
pins.
• Sample Rate
o 7 sampling frequencies 4, 5.3, 6.4, 8, 12.8, 16 and 32 kHz are available.
o Each Voice Prompt can have optimal sample rate.
• Compression Algorithms
o µ-Law: 6, 7 or 8 bits per sample
o Differential µ-Law: 6, 7 or 8 bits per sample
o PCM: 8, 10 or 12 bits per sample
o Enhanced ADPCM: 2, 3, 4 or 5 bits per sample
o Variable-bit-rate optimized compression. This allows best possible compression given a
metric of SNR and background noise levels.
• Oscillator
o Internal oscillator with internal reference: factory trimmed to ±1% deviation at room
temperature.
• Output
o PWM: Class D speaker driver to direct drive an 8Ω speaker or buzzer.
o Delivers 400mW at 3V supply.
• I/Os
o SPI interface: MISO, MOSI, SCLK, SSB for commands and digital audio data
o 6 general purpose I/O pins multiplexed with SPI interface.
