ISD2130SYIR Datasheet | Nuvoton Technology

DESCRIPTION The ISD2100 is a digital Chip Corder® providing single-chip storage and playback of high quality audio. The device features digital de-pression, prehensive memory management, flash storage, and integrated audio signal path and Class D speaker driver capable of delivering power of 400m W. This family utilizes flash memory to provide non-volatile audio playback with duration up to 30 seconds (based on 8k Hz/4bit ADPCM pression) for a single-chip audio playback solution. The ISD2100 can be controlled and programmed through an SPI serial interface or operated stand-alone by triggers applied to the device’s six GPIO pins. The ISD2100 requires no external clock sources or ponents except a speaker to deliver quality audio prompts or sound effects to enhance user interfaces. In addition, the part can provide non-volatile flash storage in 1Kbyte sectors eliminating the need for additional serial EEPROM/Flash devices. ISD2100 provides wide range of sampling frequencies, high SNR performance, low power consumption, fast programming time and integrated program verification. 2 FEATURES - Duration o ISD2130 - 30 seconds based on 8k Hz/4bit ADPCM in 1Mbit of flash storage o ISD2115A - 15 seconds based on 8k Hz/4bit ADPCM in 1Mbit of flash storage - Audio Management o Store pre-recorded audio (Voice Prompts) using high quality digital pression o Use simple index based mand 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 - 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 7 sampling frequencies 4, 5.3, 6.4, 8, 12.8, 16 and 32 k Hz are available o Each Voice Prompt can have optimal sample rate - pression 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 or 12 bits...
