MLS ChipCorder Series

ISD MLS ChipCorder® series provides high-quality, fully integrated, single-chip record/playback solutions for 6 seconds - to 16-minute messaging applications, ideal for real time recording through Microphone or Analog input in portable products. The MLS series is designed for operation in either standalone or microcontroller (SPI, I²C) mode.  Some devices incorporate a proprietary message management system that allows the chip to self-manage address locations for multiple messages. This exclusive feature provides sophisticated messaging flexibility in a simple push-button environment. The devices include an on-chip oscillator (with external resistor control) , microphone preamplifier with Automatic Gain Control (AGC) , an auxiliary analog input, anti-aliasing filter, Multi-Level Storage (MLS) array, smoothing filter, volume control, Class D/AB speaker driver, and current/voltage output.

Recordings are stored into the on-chip Flash memory cells, providing zero-power message storage. This unique single-chip solution utilizes Nuvoton’s patented multilevel storage technology. Voice and audio signals are directly stored onto memory array in their natural form, providing high-quality voice reproduction.
