ISD1600B series publication release date: dec. 01, 2008 - 3 - revision 1.22 1. general description the nuvoton ? ISD1600B chipcorder ? series is a high quality, fully integrated, single-chip single- message voice record and playback device ideally su ited to a variety of electronic systems. the message duration is user selectable in ranges from 6.6 seconds to 40 seconds, depending on the specific device. the sampling frequency of each dev ice can also be adjusted from 4 khz to 12 khz with an external resistor, giving the user greater fl exibility in duration versus recording quality for each application. operating voltage spans a range from 2.4 v to 5.5 v to ensure that the ISD1600B devices are optimized for a wide range of ba ttery or line-powered applications. the devices include an on-chip oscillator (with exter nal resistor control), microphone preamplifier with automatic gain control (agc), anti-aliasing filter, multi-level storage (mls) array, smoothing filter, pulse width modulation (pwm) class d speaker dr iver, and current output. voice signals can be fed into the chip through a differential microphone input fo r recording. the pwm out put can directly drive a standard 8 speaker or a typical buzzer, while the separate single-ended current output can drive an external amplifier. recordings are stored into the on-chip flash me mory cells, providing zero-power message storage. this unique single-chip solution is made possibl e through nuvoton?s patented multi-level storage (mls) technology. audio data are stored directly in solid-state memo ry without digital compression, providing superior quality voice and music reproduction. www.datasheet.co.kr datasheet pdf - http://www..net/

ISD1600B series publication release date: dec. 01, 2008 - 8 - revision 1.22 pin name soic / pdip functions pin no. v cca 10 analog power supply : it is important to have a separate path for each power back to the power terminal to minimize the noises. decoupling capacitors to v ssa should be as close to the device as possible. v ccp 10 v ccp : power supply for pwm speaker drivers. it is important to have a separate path for each power back to the power terminal to minimize noise. decoupling capacitors to v ssp should be as close to the device as possible. sp+ 11 speaker positive : the sp+, class d pwm output, provide a differential output with sp- pin to drive an 8 ? speaker or buzzer directly. during power down or recording, this pin is tri-stated. agc 12 automatic gain control : the agc dynamically adjusts the gain of the preamplifier to compensate the wide range of microphone input levels. the agc allows the full range of signal to be recorded with minimal distortion. nominal values of 4.7 f give satisfactory results in most cases. connecting this pin to ground provides maximum gain to the preamplifier circuitry. conver sely, connecting this pin to power supply provides minimum gain to the preamplifier circuitry. aud 13 aud : the aud provides a single-ended current output to drive an external amplifier. during standby or recording, this pin is tri-stated. r osc 14 oscillator resistor : this enables the user to vary the record and/or playback duration of the device. a resistor connected between the r osc pin and v ssa determines the sample frequency for the ISD1600B device. please refer to the duration section in section 6.1. v ccd 15 digital power supply : it is important to have a separate path for each power back to the power terminal to minimize noise. decoupling capacitors should be as close to the device as possible. 16 led output : this pin is low during a record cycle and blinks during playback cycle. it can be used to drive an led to indicate either a record or playback cycle is in progress. led note: [1] 600k (typical). www.datasheet.co.kr datasheet pdf - http://www..net/
ISD1600B series publication release date: dec. 01, 2008 - 9 - revision 1.22 6. functional description 6.1. d etailed d escription 6.1.1 audio quality nuvoton?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 comp lete 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 6.6 secs 8 secs 10.6 secs 13.3 secs 8 khz 80 k 10 secs 12 secs 16 secs 20 secs 6.4 khz 100 k 12.5 secs 15 secs 20 secs 25 secs 5.3 khz 120 k 15 secs 18 secs 24 secs 30 secs 4 khz 160 k 20 secs 24 secs 32 secs 40 secs 6.1.3 flash storage the ISD1600B product utilizes the on-chip fl ash 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 oper ations are explained in section 6.2. 6.1.5 automatic power-down mode at the end of a playback or record cycle, the ISD1600B device automatically enters into a low- power mode, consuming typi cally 1a, provided that playe , playl and rec are high (see dc parameters section). during a playback cycle, the device powers down automatically at the end of the message. during a record cy cle, the device powers down immediately after rec is released to high. 6.2. f unctional d escription e xample the following example operating sequences demonstrate the functionality of the ISD1600B series. www.datasheet.co.kr datasheet pdf - http://www..net/
ISD1600B series publication release date: dec. 01, 2008 - 10 - revision 1.22 6.2.1. record a message the device starts recording from the beginning of the memory when rec transits from high to low and stays at low. a record cycle is completed when rec is pulled to high or entire memory is filled up. then an end-of-message (eom ) marker is written at the end of message, enabling a subsequent playback cycle to term inate appropriately. hence, the device automatically enters into standby mode. record takes precedence over playback operation. if rec is pulled low during a playback cycle, the playback immediately halts and record ing starts from the beginning of the memory. holding rec low after recording will increase standby current consumption. 6.2.2. edge-trigger playback a playback operation starts from the beginning of the memory when playe detects a low going signal exceeding the specified debounced time. playback continues until an eom marker is encountered. upon completion of a pl ayback cycle, the devic e automatically enters into standby mode. during playback, a subsequent low going signal will terminate the current playback operation. holding this pin low after playback operati on will increase standby current consumption. 6.2.3. level- trigger playback playl when switches from high to low and stays at low, a playback starts from the beginning of the memory until either an eom mark er is reached, then it automatically powers down. playl if is pulled high at any time during pl ayback, the playba ck operation stops immediately and the device enters into the power-down mode. 6.2.4. led operation the led is low during recording, which turns on an led as a recording indicator. however, during playback, the led blinks a few times per second to indicate a playback operation. it returns to a high when operation stops. 6.2.5. r osc operation the duration can be varied by changing the value of r osc . this means the designer has the flexibility to choose different sampling frequency, up to 12 khz, depending upon the needs. this feature allows frequency shifting where a recorded audio can be played back faster or slower than normal for special sound effects. another feature is a ?pause? function that can be activated by taking the r osc resistor to v cc to stop playback momentarily, and to resume when the resistor is switched back to ground. www.datasheet.co.kr datasheet pdf - http://www..net/
