 ISD2361
ISD2361
1 GENERAL DESCRIPTION
The ISD2361 is a playback only digital ChipCorder® based on flash storage. The device
features both internal and external flash support, digital de-compression,
comprehensive memory management, integrated audio signal path with up to 3
channel concurrent playback. The ISD2361 integrates a Class D speaker driver
capable of delivering 1W power output.
The ISD2361 requires no external clock sources or components to operate. It can
operate under SPI mode, or operate in stand-alone by detecting on level transition on
its GPIO pins.
The ISD2361 has 2Mbit non-volatile flash built-in, and supports external NOR serial
flash up to 2G bit.
2 FEATURES
Duration
o 64 seconds based on 8kHz/4bit ADPCM in 2Mbit of internal flash storage
o With external memory – total addressable space is 2Gbit (1092minutes)
Audio Management
o Store pre-recorded audio (Voice Prompts) using high quality digital compression
o Use simple index based command for playback – no address needed.
o Execute pre-programmed macro scripts (Voice Macros) designed to control the configuration
of the device and playback Voice Prompts sequences.
Path and playback Control
o Up to 3 channel audio streaming can be mixed and played back concurrently
o Each channel has independent counter which enables user micro-management on VM
execution
o Mask Jump allows branch execution depending on internal register or external GPIO pin
status
Control
o Serial SPI interface for microprocessor control and programming.
o Stand-alone control where customized Voice Macro scripts are assigned to GPIO trigger
pins.
Sample Rate
o 8 sampling frequencies – 4, 5.3, 6.4, 8, 10.67, 12.8, 16 and 32 kHz are available.
o Each Voice Prompt can have optimal sample rate.
Compression Algorithms
o µ-Law: 6, 7 or 8 bits per sample
o Differential µ-Law: 6, 7 or 8 bits per sample
o PCM: 8, 10, 12 or 16 bits per sample
o Enhanced ADPCM: 2, 3, 4 or 5 bits per sample
o Variable-bit-rate optimized compression. This allows best possible compression given a
metric of SNR and background noise levels.
Oscillator
o Internal oscillator with internal reference: factory trimmed to ±1% deviation at room
temperature.
Output
o PWM: Class D speaker driver to direct drive speaker or buzzer.
o Delivers 1.1W at 5.5V on 8Ω load.
