San Jose, CA--July 29, 1996--ISD (Information Storage Devices Inc., San Jose, CA) announced the ISD33000 series, the 3 V, single-chip record and playback products optimized for portable phones.
The product family is optimized for both analog and digital cellular phones--including personal communication service (PCS), personal handy phone system (PHS), global system mobile, (GSM), Japanese digital cellular (JDC), and cordless phones that rely on 3 V technologies to minimize power consumption. The single-chip solutions are designed to be integrated into phones to sere a built-in answering machines and voice memo pads.
In addition to offering true 3 V (2.7 to 3.3 V) operation, the new ISD33000 product family offers longer recording durations than previous ISD products: up to four minutes. Due to a new ISD chip architecture, the ISD33000 series can be integrated into portable products. Specifically, the series offers a highly integrated serial interface, minimizing pin count and circuit traces.
A new AutoMute feature has been added into the ISD33000 series to virtually eliminate any background noise occurring during playback of silent periods or pauses in audio recordings. The CMOS ISD33000 chips integrate a nonvolatile memory array, oscillator and audio amplifier to provide a complete record and playback system-on-a-chip for portable phones.
The ISD33000 series will offer seven product variations:
- The ISD33060 will record up to 1 minute of audio information at a sampling rate of 8 kHz;
- ISD33075; 75 seconds at 6.4 kHz;
- ISD33090; 1.5 minutes at 5.3 kHz;
- ISD33120; 2 minutes at 8 kHz;
- ISD33150; 2.5 minutes at 6.4 kHz;
- ISD33180; 3 minutes at 5.3 kHz; and
- ISD33240; 4 minutes at 4 kHz.
Samples of the ISD33000 series will be available in August for 2-4 minute durations, and in October from 1-1.5 minute durations, through ISD's direct sales offices, worldwide network of distribution channels and sales representatives. The chips are scheduled to be in full production by November and February, respectively, available in either die form, 28-pin SOIC, PDIP, or TSOP (8 by 13.4 mm) packages. Chips in the ISD33000 series will be priced at between $8.30 and $16.60, depending upon recording durations, packaging and temperature requirements, for quantities of 50,000 units.
