ISD2361
ISD2361 is ISD ChipCorder manufactured by Nuvoton Technology.
DESCRIPTION
ISD2361 is a playback only Digital Chip Corder® family product based on flash storage. The device features both internal and external flash support, digital de-pression, prehensive memory management, integrated audio signal path with up to 3 channel concurrent playback and a Class D speaker driver capable of delivering 1W power output. ISD2361 requires no external clock sources or ponents to operate. It can operate under SPI mode, or operate in stand-alone by detecting on level transition on its GPIO pins. ISD2361YYI has 2Mbit non-volatile flash built-in, and can support external NOR serial flash up to 2G bit. ISD2361SYI has 2Mbit non-volatile flash built-in only and cannot support external NOR serial flash.
2 FEATURES
- Performance Enhancements o Support external flash (ISD2361YYI) o GPIO trigger reliability o Better DPWM output SNR o Audio output power efficiency
- Duration o 64 seconds based on 8k Hz/4bit ADPCM in 2Mbit of internal flash storage o ISD2361YYI with external memory
- total addressable space is 2Gbit (1092minutes)
- Audio Management o Store pre-recorded audio (Voice Prompts) using high quality digital pression o Use simple index-based mands 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 Audio streaming for up to 3 channels can be mixed and played back concurrently o Each channel has independent counter which enables user micro-management on VM execution o Mask Jump for branch execution; based on internal register or external GPIO pin
- Chip Control o Serial Peripheral Interface (SPI) for microprocessor control and programming o Standalone control when customized Voice Macro scripts are assigned to GPIO trigger pins
- Sample Rates o 8 sampling frequencies available: 4, 5.3, 6.4, 8, 10.67, 12.8, 16 and 32 k Hz o Each Voice Prompt can have its own optimal sample rate
