 MLS-Chipcorder

The ISD MSL 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 MSL series is designed for operation in either standalone or microcontroller (SPI, I?C) 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. For Playback only applications See ISD Digital ChipCorderSeries.
