MAMP580 vocoder chip

详情

MAMP**0 is a low bit rate speech vocoder chip developed by Shenzhen Microdevice Technology Co. Ltd, which is based on MELPe standard, supporting 3 types of encoding bit rate: ***0bps, ***0bps and **0bps.

MAMP**0 has built-in FLASH and RAM and can do real-time speech encoding/decoding with single chip, no need for external storage, which make it very simple for users to design their systems.

MAMP**0 has an internal CODEC with built-in ADC, DAC, analog amplifiers and filters, no need for external CODEC. It can directly connect micphone and earphone(speaker) as a real single chip speech encoding/decoding solution. While, MAMP**0 also has a standard PCM interface, through which it can connect external CODECs to meet some users requirement.

MAMP**0 connects to MCU with UART. User can read and write encoded speech data and configuration data using UART , which is asynchronous and full-duplex.

MAMP**0 packs in LQFP*8 package and has a quite low power consumption.
