ISD Announces New Sound Developement & Programming Systems

ISD-SD200/203 Series

The ISD-SD200/203 Universal Sound Development and Programming System offers a PC-based, sound file editor and programmer for ISD33000 series products. A new Microsoft Windows^® version of the Sound Mapper™ software lets users graphically edit and precisely program one or more sound files onto multiple ISD33000 chips. This system lets manufacturers program a master recording and copy it onto all ISD chips, e.g., for pre-recorded outgoing messages in portable phone TADs, or for pre-programmed messages in exact locations of the ISD33000 series products.

The ISD-SD200/203 system consists of one Main System Module (ISD-SD200), one eight socket Programming Pod (ISD-SD203P/E) or Handler Interface (ISD-SD203H), Sound Mapper application software and necessary cabling. The Main System Module attaches directly to one of three different Programming Pods. Programming Pods have eight sockets for either the `P'-PDIP package (ISD-SD203P), `E'-TSOP package (ISD-SD203E) or a special handler interface (ISD-SD203H) for high volume production needs. The ISD-SD200 system lets users maximize message storage and program multiple ISD ChipCorder^® products simultaneously.

The ISD-ES301 Development System

The ISD-ES301 Development System is designed for customer application development and ISD33000 product evaluation. The ISD-ES301 provides a platform for developing microcontroller software to control any product within the ISD33000 ChipCorder series. The features provided by the ISD-ES301 development system include: a parallel port interface for PC control to the SPI port of the ISD33000 device; an external interface for direct ISD33000 device manipulation; on-board microphone and external speaker; automatic gain control for microphone input; and internal battery power.

The ISD-ES301 also includes a socket for a Motorola 68HC705-C4A microcontroller which interfaces to the ISD33000, the LCD display and the keypad. Firmware written for the Motorola 68HC705-C4A microcontroller provides a user interface for controlling the ISD33000 device. The firmware for the Motorola 68HC705-C4A microcontroller is provided as an application example. A PC DOS-based program written in "C" programming language is also provided. This software interfaces to the ISD-ES301 Development System using the PC's parallel port and has the same functionality as the microcontroller user interface firmware.

"Our new Windows interface for the ISD-SD200/203 Series simplifies the sound editing and programming process for our customers" said Phillip Pyo, director of product marketing for ISD. He added that, "The ES301 Development System gives designers a platform to test and emulate with the ISD33000 before system integration. In addition, the microcontroller code for message management, offered with this system, should help our customers bring their applications to market more quickly."

ISD33000

The ISD33000 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-volt technologies to minimize power consumption. The single-chip solutions are designed to be integrated into phones to serve as built-in answering machines and "hands free" voice memo pads. ISD also expects the chips to be integrated into voice pagers, personal voice organizers, personal digital assistants, portable instrumentation equipment and tapeless pocket recorders. In addition to offering true 3-volt (2.7 to 3.3V) operation, the new ISD33000 product family offers recording durations up to four minutes.

Availability and Pricing

The ISD-SD200 Main System Module is currently available and is now priced at $1,235 US. The ISD-SD203P Programming Pods for PDIP packaged devices (8 sockets) or the ISD-SD203E for TSOP (28 lead) packaged devices (8 sockets) are currently available and are each now priced at $1,640 US. The ISD -SD203H Handler Interface (for large volume production) will be available in the second quarter 1997 at a price still to be determined. The ISD-ES301 will be available in February, 1997 and is expected to be priced at $495 US.
