ISD1916 1. GENERAL DESCRIPTION Winbond’s ISD1916 ChipCorder® is a new single-chip multiple-message record/playback series with dual operating modes (address trigger and direct trigger) with wide operating voltage ranging from 2.4V to 5.5V. The sampling frequency can be selected from 4 to 12 kHz via an external resistor, which also determines the duration from 10.6 to 32 seconds.
ISD1916 2.1. Address trigger operational mode • While in address. NORM mode, flexible message duration is defined by start address and end • Utilize four start addresses ( S0 , S1 , S2 & S3 ) and four end addresses ( E0 , E1 , E2 & E3 ) to specific the message duration. 2.2. • REC • PLAYE : Edge-trigger playback from start to end addresses and stops at EOM marker, if EOM is prior to end address. Toggle on-off. • PLAYL : Level-hold playback from start to end addresses.

ISD1916 5. PIN DESCRIPTION PIN NAME VSSD S0 / M1 PIN # 1 2 I/O I I FUNCTION Digital Ground: Ground path for digital circuits. [1] S0 : In Norm mode, Start Address Bit 0. is active, low active operation on 1st Message. Internal pull-up M1 : When MODE S1 / M2 3 I & debounce existed. [1] S1 : In Norm mode, Start Address Bit 1. M2 : When MODE S2 / M3 4 I is active, low active operation on 2nd Message. Internal pull-up & debounce existed. [1] S2 : In Norm mode, Start Address Bit 2.
ISD1916 PIN NAME MIC- PIN # 19 I/O I FUNCTION MIC- : Inverting input of the differential microphone signal. While FT is enabled, MIC- pin is disabled and must be floated. Oscillator Resistor: Connect an external resistor from this pin to VSSA to select the internal sampling frequency. Analog Power Supply: Power supply for analog circuits. Rosc 20 I VCCA LED 21 22 I O PLAYE / FMC2 23 I PLAYE : In Norm mode, low active input, edge-trigger playback from start to end addresses & toggle on-off.
ISD1916 6. FUNCTIONAL DESCRIPTION There are two operational modes: address trigger ( NORM ) and direct trigger ( MODE ). After a new condition is selected on NORM / MODE , the power must be cycled to enable it. 6.1. ADDRESS TRIGGER ( NORM ) OPERATION The start address bits ( S0 , S1 , S2 & S3 ) and end address bits ( E0 , E1 , E2 & E3 ) are used to access the memory location and they can divide the memory into a maximum of 16 slots.

ISD1916 6.1.2. Edge-triggered Playback ( PlayE ) Operation • • Low active input, edge-trigger, toggle on-off, debounce required. Playback begins from the start address to end address or EOM, whichever is occurred first. • • • At the end of message, LED pulses Low momentarily. Then device will automatically power down. During playback, a subsequent trigger terminates the playback operation. If EOM marker is not encountered, then LED will not pulses Low momentarily.

XCLK Feature • When precision sampling frequency is required, external clock mode can be activated by setting XCLK to Low. Under such condition, the resistor at Rosc pin must be removed and the external clock signal must be applied to the Rosc pin. These conditions must be satisfied prior to any operations.

Rosc Operation • • • • When the ROSC varies from 53.3 KΩ to 160 KΩ, the sampling frequency changes from 12 to 4 kHz accordingly. When ROSC resistor value is changed during playback, the tone of a recorded message will alter either faster or slower.
ISD1916 • If PlayL is held at Low during power turns on and constantly maintained at Low, the device will play the message repeatedly, with insignificant dead time between messages regardless of sampling frequencies. This status will sustain unless power is turned off or PlayL somehow returns to High. 6.3.5. Automatic Single Message Playback • If LED is connected to PlayE , once PlayE is triggered, then the device plays message repeatedly without power down between the looping playback.
