9 / 23 page ISD1600B SERIES Publication Release Date: Jan. 23, 2007 - 9 - Revision 1.2 6. FUNCTIONAL DESCRIPTION 6.1. DETAILED DESCRIPTION 6.1.1 Audio Quality Winbond’s patented ChipCorder ® MLS technology provides natural high quality record and playback solution on a single chip. The input audio signals are stored directly into the non- volatile memory and are reproduced in its natural form without any compression artifacts caused by the digital speech solutions. A complete sample is stored in a single cell, minimizing the memory needed to store a single message. 6.1.2 Duration The ISD1600B series offer single-chip solution with record & playback duration from 6.6 seconds to 40 seconds. Sampling frequency and duration are determined by an external resistor connected to the Rosc pin. Sampling Frequency Rosc ISD1610B ISD1612B ISD1616B ISD1620B 12 KHz 53 k Ω 6.6 secs 8 secs 10.6 secs 13.3 secs 8 KHz 80 k Ω 10 secs 12 secs 16 secs 20 secs 6.4 KHz 100 k Ω 12.5 secs 15 secs 20 secs 25 secs 5.3 KHz 120 k Ω 15 secs 18 secs 24 secs 30 secs 4 KHz 160 k Ω 20 secs 24 secs 32 secs 40 secs 6.1.3 Flash Storage The ISD1600B product utilizes the on-chip Flash memory providing zero-power message storage. The message is retained for up to 100 years without power. In addition, the device can be re-recorded typically over 100,000 times. 6.1.4 Basic Operation The ISD1600B ChipCorder ® device is controlled by either the REC , or one of the two playback modes, PLAYE and PLAYL . The ISD1600B parts are configured for simple design in single-message application. Detailed operations are explained in Section 6.2. 6.1.5 vAlert With vAlert option, after Record, the LED blinks slowly to indicate a new message exists. Once playback is performed, the LED will not blink again and resume to normal operating conditions. 6.1.6 Automatic Power-Down Mode At the end of a playback or record cycle, the ISD1600B device automatically enters into a low- power mode, consuming typically 1µA, provided that PLAYE , PLAYL and REC are High (see DC parameters Section). During a playback cycle, the device powers down automatically |
