2 / 88 page ISD5100 – SERIES - 2 - 1. GENERAL DESCRIPTION The ISD5100 ChipCorder Series provide high quality, fully integrated, single-chip Record/Playback solutions for 1- to 16-minute messaging applications that are ideal for use in cellular phones, automotive communications, GPS/navigation systems and other portable products. The ISD5100 Series products are an enhancement of the ISD5000 architecture, providing: 1) the I 2C serial port - address, control and duration selection are accomplished through an I 2C interface to minimize pin count (ONLY two control lines required); 2) the capability of storing digital data, in addition to analog data. This feature allows customers to store phone numbers, system configuration parameters and message address locations for message management capability; 3) Various internal circuit blocks can be individually powered-up or -down for power saving. The ISD5100 Series include: • ISD5116 from 8 to 16 minutes • ISD5108 from 4 to 8 minutes • ISD5104 from 2 to 4 minutes • ISD5102 from 1 to 2 minutes Analog functions and audio gating have also been integrated into the ISD5100 Series products to allow easy interface with integrated digital cellular chip sets on the market. Audio paths have been designed to enable full duplex conversation record, voice memo, answering machine (including outgoing message playback) and call screening features. This product enables playback of messages while the phone is in standby, AND both simplex and duplex playback of messages while on a phone call. Additional voice storage features for digital cellular phones include: 1) a personalized outgoing message can be sent to the person by getting caller-ID information from the host chipset, 2) a private call announce while on call can be heard from the host by giving caller-ID on call waiting information from the host chipset. Logic Interface Options of 2.0V and 3.0V are supported by the ISD5100 Series to accommodate portable communication products (2.0- and 3.0-volt required). Like other ChipCorder ® products, the ISD5100 Series integrate the sampling clock, anti-aliasing and smoothing filters, and the multi-level storage array on a single-chip. For enhanced voice features, the ISD5100 Series eliminate external circuitry by integrating automatic gain control (AGC), a power amplifier/speaker driver, volume control, summing amplifiers, analog switches, and a car kit interface. Input level adjustable amplifiers are also included, providing a flexible interface for multiple applications. Recordings are stored into on-chip nonvolatile memory cells, providing zero-power message storage. This unique, single-chip solution is made possible through Winbond’s patented multilevel storage technology. Voice and audio signals are stored directly into solid-state memory in their natural, uncompressed form, providing superior quality on voice and music reproduction. |
