ISD5116
1. GENERAL DESCRIPTION
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 I
2
C serial port - address,
control and duration selection are accomplished through an I
2
C 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.
