Modul

LORECA LOR2201BCR CloudLinkTM Hearing Aids Bluetooth System-in-Package

The module is specifically designed for hearing aid devices requiring

communication, high performance audio processing capabilities and programming

flexibility when form−factor and power consumption are key design constraints

The L O R 2 2 0 1 B C R SiP module is a hearing aid processing system,

based on RISC-VMCU, mixed−signal audio processing system, 32bit

Risc Core for link management.Compaction for hearing aid devices，

connection for audio source and communication.

.
