ISD1800 SERIES 6. PIN DESCRIPTION PIN NAME PIN NO. I/O FUNCTION VSSD, VSSA 1, 16 REC 1 2 I Record: The REC input is an active-HIGH record signal. The device records whenever REC is HIGH. This pin must remain HIGH for the duration of the recording. REC takes precedence over either playback (PLAYL or PLAYE) signal. If REC is pulled HIGH during a playback cycle, the playback immediately ceases and recording begins. A record cycle is completed when REC is pulled LOW.

ISD1800 SERIES PIN NAME PIN NO. I/O FUNCTION MIC 10 I Microphone Input: The microphone input transfers its signals to the on-chip preamplifier. An on-chip Automatic Gain Control (AGC) circuit controls the gain of the preamplifier. An external microphone should be AC coupled to this pin via a series capacitor. The capacitor value, together with an internal 10 KΩ resistance on this pin, determines the low-frequency cutoff for the I1800 passband.

ISD1800 SERIES PIN NAME PIN NO. I/O FUNCTION VCCA, VCCD 18, 27 ROSC 19 I The Resistor Controlled Oscillator input: This enables the user to vary the I1800 device record and playback duration. The resistor connected between the ROSC pin and VSS (R2) determines the sample frequency and the filter upper pass band for the I1800 device. Please refer to the table in Duration Section for duration selection. FT 25 I Feed Through: This mode allows use of the speaker drivers for external signals.

ISD1800 SERIES 7. FUNCTIONAL DESCRIPTION 7.1. DETAILED DESCRIPTION Speech/Sound Quality Winbond’s patented ChipCorder® technology provides natural record and playback. The input voice signals are stored directly in nonvolatile cells and are reproduced without the synthetic effect often heard with digital solid-state speech solutions. A complete sample is stored in a single cell, minimizing the memory necessary to store a single message.
PAGE 10
ISD1800 SERIES 7.2. FUNCTIONAL DESCRIPTION EXAMPLE The following example operating sequence demonstrates the functionality of the ISD1800 devices. 1. Record a message filling the memory Pulling the REC pin HIGH initiates a record cycle form the beginning of the message space. The device will automatically power down after REC is release LOW. An EOM marker is written at the end of message. If REC is held HIGH, the recording continues until the message space has been filled.
PAGE 11
ISD1800 SERIES 8. RECLEDoperation The RECLED output pin provides an active-LOW signal, which can be used to drive an LED as a “record-in-progress” indicator. It returns to a HIGH state when the REC pin is released LOW or when the recording is completed due to the memory being filled. This pin also pulses LOW to indicate the end of a message has been reached. 9. ROSC operation The duration of the device can be varied by changing the value of R2 (ROSC).
