ISDMP Datasheet(PDF) – Winbond

Oct 31, – 1 – Revision 1. Oct 31, – 2 – Revision 1.

The CMOS-based devices include an on-chip oscillator, anti-aliasing filter, smoothing filter, AutoMute feature, audio amplifier, and high density multilevel Flash memory array. The ISD series is designed to be used in a dtaasheet or microcontroller-based system.

ISD4004 Datasheet PDF

Oct 31, – 4 – Revision 1. Oct 31, Revision 1.

This is the serial input to the ISD device when it is configured as slave. This is the serial output of the ISD isd44004 To minimize noises, the analog and digital circuits in the ISD devices use separate power busses.


In addition, these supplies should be decoupled as close to the package as possible.


The duty cycle on the input clock is not critical, as the clock is immediately divided by two. If the XCLK is not used, this input must be connected to ground. In addition, the device can be re- recorded typically overtimes. Memory Architecture The ISD series dahasheet a total of 3,K Flash memory cells, which is organized as 2, rows of 1, cells each.

The address bits A0-A15 are used to access various rows for multiple messages of different durations. Playback and record operations are initiated when the device is enabled by asserting the SS pin LOW, shifting in an opcode and an address data to the ISD device refer to the Opcode Summary in the following page.

Message Cueing can be selected only at the beginning of a playback operation. Care should be taken such that vatasheet data shifted in is compatible with current system operation possible to read interrupt data and start a new operation at the same time Otherwise the ISD will repeat the operation from the same row address. In this mode, the messages are skipped 1, times faster than the normal playback mode.


Refer to the AC timing table for other T to different sampling rates. Stresses above those listed may cause permanent damage to the darasheet. Exposure to the absolute maximum ratings may affect device reliability and performance.

Functional operation is not implied at these conditions. When a record command is sent, T [11] Measured with AutoMute feature disabled.
