ESCRIPTION
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.
Duration
The I1800 devices offer single-chip solutions with 6 to 16 seconds of record/playback duration
capacity. Sampling rate and duration are determined by an external resistor connected to the ROSC
pin. These specifications apply with the required resistor value for playback duration.

Non-Volatile Storage
The
I1800
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 10,000 times.
Basic Operation
The
I1800
ChipCorder device is controlled by the REC pin, and either of two playback pins, PLAYE
(edge-activated playback), and PLAYL (level-activated playback). The
I1800
parts are configured for
design simplicity in a single-message application. Device operation is explained in section 7.2,
“Functional Description Example”.
Automatic Power-Down Mode
At the end of a playback or record cycle, the
I1800
device automatically returns to a low-power
standby mode, consuming typically 0.5μA, provided that Play REC, XCLK, and FT pins are LOW (see
DC parameters, section 10). During a playback cycle, the device powers down automatically at the
end of the message. During a record cycle, the device powers down immediately after REC is
released LOW.
