Timberwolf Digital Signal Processor family,
powered by AcuEdge™ Technology
Sound Classifier, designed for Connected Home applications
ZL38062
Preliminary Data Sheet
Description
The ZL38062 is part of Microsemi’s Timberwolf audio
processor family of products that feature the
company’s innovative AcuEdge acoustic technology,
which is a set of highly-complex and integrated
algorithms. These algorithms are incorporated into a
powerful DSP platform that allow the user to extract
intelligible information from the audio environment.
The Microsemi AcuEdge Technology ZL38062 device
is ideal for Connected Home applications. Its license-
free, royalty-free intelligent ZLS38062 audio Firmware
provides Sound Classification capabilities, Acoustic
Echo Cancellation (AEC), Noise Reduction (NR) and a
variety of other voice enhancements to improve both
the intelligibility and subjective quality of voice in harsh
acoustic environments.
Microsemi offers additional tools to speed up the
product development cycle. The MiTuner™ ZLS38508
or ZLS38508LITE GUI software packages allow a
user to interactively configure the ZL38062 device.
The optional MiTuner ZLE38470BADA Automatic
Tuning Kit provides automatic tuning and easy control
for manual fine tuning adjustments.
Applications
• Security cameras and monitoring systems
• Smoke/Fire and Carbon Monoxide alert reporting
• Integrated smart home gateways
• Intercoms

ZLS38062 Firmware
There are three Firmware images that may be selected
to provide the desired operating mode. Firmware
images can be swapped during normal operation to
switch modes dynamically. Firmware image size varies
with firmware load.
ZLS38062.1 (Alarm Detector)
• Detects T3 (Temporal smoke alarm) signals
• Detects T4 (Temporal carbon monoxide alarm)
signals
• Low power listening mode
ZLS38062.2 (Glass Break and Energy Detectors)
• Detects the sound of breaking glass
• Programmable Energy Detector
• Detects T3 (Temporal smoke alarm) signals
• Detects T4 (Temporal carbon monoxide alarm)
signals
ZLS38062.0 (Full Duplex Communication)
• Full Narrowband and Wideband Acoustic Echo
cancellation operation
• Supports long tail AEC (up to 256 ms)
• Non-Linear AEC provides higher tolerance for
speaker distortions
• Non-Linear processor
• G.168 Line Echo Canceller
• Howling detection/cancellation
• Prevents oscillation in AEC audio path
• Advanced noise reduction reduces background
noise from the near-end speech signal using
Psychoacoustic techniques

ZL38062
Preliminary Data Sheet
ZLS38062.0 (Full Duplex Communication) (cont.)
• Provisions for stereo audio mixing (sample rate of
44.1 or 48 kHz) and stereo music record and
playback (sample rate of 48 kHz) with 8 kHz or
16 kHz voice processing
• Various encoding/decoding options:
• 16-bit linear, G.722, G.711 A/μlaw
• Send and receive path equalizers
• Caller ID Type 1 & 2
• Programmable tone generation
• DTMF detection
• Dual 16-bit digital-to-analog converters (DAC)
• Sampling up to 48 kHz and internal output
drivers
• Headphone amps capable of 4 single-ended or
2 differential outputs
• 32 mW output drive power into 16 ohms
• Impulse pop/click protection
• 1 Digital Microphone input supporting
1 or 2 Microphones
• 2 TDM ports shared between PCM and
Inter-IC Sound (I2S)
• Each port can be a clock master or a slave
• Each port supports delayed and non-delayed
(GCI) timing and I2S normal and left justified
modes
• Each port provides sample rate conversion
and synchronous TDM bus operation
ZL38062 Hardware Features
• DSP with Voice Hardware Accelerators
• SPI or I2C Slave port for host processor interface
• General purpose UART port for debug
• Master SPI port for serial Flash interface
• Boots from SPI or Flash
• Can run unattended (controllerless), self-
booting into a configured operational state
• Flash firmware can be updated from SPI Slave
• 14 General Purpose Input/Output (GPIO) pins (11
with the 56 pin WLCSP)
• 2 low power modes controlled by reset
The MiTuner™ Automatic Tuning Kit and
ZLS38508 MiTuner GUI
Microsemi's Automatic Tuning Kit option includes:
• Audio Interface Box hardware
• Microphone and Speaker
• ZLS38508 MiTuner GUI software
• Allows tuning of Microsemi's AcuEdge
Technology Audio Processor
The ZLS38508 software features:
• Auto Tuning and Subjective Tuning support
• Allows tuning of key parameters of the system
design
• Provides visual representations of the audio paths
with drop-down menus to program parameters,
allowing:
• Control of the audio routing configuration
• Programming of key building blocks in the
transmit (Tx) and receive (Rx) audio paths
• Setting analog and digital gains
• Configuration parameters allow users to “fine
tune” the overall performance
Tools
• ZLK38000 Evaluation Kit
