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.
