Motorola Integrates ISD Chips into GSM Phones

Motorola has integrated Information Storage Devices' (ISD's) voice record and playback chips into its new cd900 family of dual-band GSM digital cellular phones. The Motorola phones contain the VoiceNote memo recorder, which is powered by ISD's ISD33180 +3 VDC single-chip record and playback products. Through VoiceNote, the Motorola phones can offer up to three minutes of message recording for storing memos and recording phone calls.

The ISD33180 is a member of the ISD33000 family of voice record and playback chips. Optimized for both analog and digital phones, these +3 VDC chips serve as built-in answering machines and voice memo pads while providing on the fly recording functionality. They do not require battery power to retain recorded messages. Messages can be recorded and re-recorded reliably over 100,000 times.
