Advanced Information

PRELIMINARY

FUNCTIONAL DESCRIPTION

O

The I5216 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 PBX systems, cellular

phones, automotive communications, GPS/navigation systems, and other portable products. The I5216

product is an enhancement to the ISD5116 architecture, providing: 1) A full duplex Voice CODEC with

µ-Law and A-Law compander, with I2S and PCM interface ports; 2) A 2.2V microphone bias supply for

reduced noise coupling. This supply can also be used to power down the external microphone with the

system.

Analog functions and audio gating have also been integrated into the I5216 product to allow for easy

interfacing with integrated chip sets on the market. Audio paths have been designed to enable full

duplex conversation record, voice memo and answering machine (including outgoing message

playback).

Logic Interface Options of 2.0V and 3.0V are supported by the I5216 to accommodate both portable

communication (2.0- and 3.0-volt required) and automotive product customers (5.0-volt required).

Like other ChipCorder products, the I5216 integrates the sampling clock, anti-aliasing and smoothing

filters, and multi-level storage array on a single chip. For enhanced voice features, the I5216 eliminates

external circuitry by integrating automatic gain control (AGC), a power amplifier/speaker driver, volume

control, summing amplifiers, analog switches, and a Voice CODEC. Input level adjustable amplifiers

are also included, providing a flexible interface for multiple applications.

Recordings are stored in 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.

SPEECH/SOUND QUALITY

The I5216 ChipCorder product can be configured, via software, to operate at 4.0, 5.3, 6.4, and 8.0 kHz

sampling frequencies, allowing the user a choice of speech quality options. Increasing the duration

decreases the sampling frequency and bandwidth, which affects sound quality. The "Input Sample

Duration" table below compares filter pass band and product durations.

DURATION

To meet end-system requirements, the I5216 device is a single-chip solution, which provides 8 to 16

minutes of voice record and playback, depending on the sample rates defined by the customer's

software.
