AK7756VF Descrição geral
GENERAL DESCRIPTIONThe AK7756 is a highly integrated digital signal processor, including a mono voice audio codec, a MIC pre-amplifier and digital audio I/F. The audio DSP has 9216step at fs = 8kHz parallel processing power. As the AK7756 is a RAM based DSP, it is programmable for user requirements such as hands free and acoustic effect. The AK7756EN is available in a space saving small 28pin QFN package and the AK7756VF is available in a 30pin VSOP package.FEATURES□ DSP - Word length: 24bit (Data RAM 24bit floating point) - Instruction cycle: 13.6 ns (9216 steps at fs=8 kHz) - Multiplier 20 x 20 → 36bit (double precision available) - Divider 20 / 20 → 20bit - ALU: 36bit arithmetic operation (with overflow margin 4bit) 24bit floating point arithmetic and logic operation - Program RAM: 3072 x 36bit - Coefficient RAM: 2048 x 20bit - Data RAM: 1024 x 24-bit (24bit floating point) - Delay RAM: 3072 x 20bit, 3072 x 20bit - Master Clock: 4.6MHz ~ 73.7MHz - JX pins (Interrupt)□ Audio Serial I/F - Master / Slave operation - Right / Left justified and I2S - PCM (Short / Long Frame) - 16bit linear, 8bit A-law, 8bit µ-law□ Mono CODEC - Sampling Rate 8KHz, 16KHz - DAC S/N: 91dB, S/(N+D): 83dB (fs:16kHz) - ADC S/N: 86dB, S/(N+D): 77dB (fs:16kHz)□ Microphone interface - Differential or single-ended input - Programmable Gain (+33dB ~ +15dB and 0dB, 3dB step) - Low Noise Microphone Bias□ Automatic Power Down (CODEC, DSP)□ μP I/F : SPI, I2C-slave□ I2C bootloader□ Power supply Analog (AVDD) : 3.0V ~ 3.6V (typ.3.3V) Digital1 (DVDD) : 3.0V ~ 3.6V (typ.3.3V) Digital2 (DVDD18) : 1.7V ~ 1.9V (typ.1.8V)□ Operating temperature range: -20°C ~ 85°C (AK7756EN), -40°C ~ 85°C (AK7756VF)□ Package: 28pin QFN (AK7756EN) 30pin VSOP (AK7756VF)
