Introduction

The ISD5116 ChipCorder Product provides high quality, fully integrated, single-chip Record/Playback solutions for 8- to 16-minute messaging applications that are ideal for use in cellular phones, automotive communications, GPS/navigation systems and other portable products. The ISD5116 product is an enhancement of the ISD5000 architecture, providing: 1) the I²C serial port - address, control and duration selection are accomplished through an I²C interface to minimize pin count (ONLY two control lines required); 2) the capability of storing digital data, in addition to analog, information. These features allow customers to store phone book numbers, system configuration parameters and message address pointers for message management capability. Analog functions and audio gating have also been integrated into the ISD5116 product 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 ISD5116 to accommodate portable communication products customers (2.0- and 3.0-volt required). Like other ChipCorder products, the ISD5116 integrates the sampling clock, anti-aliasing and smoothing filters, and the multi-level storage array on a single-chip. For enhanced voice features, the ISD5116 eliminates 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 voice and music reproduction.
