ISD1210S

Overview

The ISD1210S is a single-chip voice record and playback device from the ISD1200 series, manufactured by Winbond. It provides a 10-second recording duration with a sampling frequency of 6.4 kHz and a filter passband of 2.6 kHz. The device operates on a single +5V supply and features an on-chip oscillator, microphone preamplifier, automatic gain control, and speaker amplifier. Recordings are stored in nonvolatile memory, allowing for zero-power message storage with a typical retention of 100 years and 100,000 record cycles. It supports fully addressable multiple messages via eight address pins.

Feature Summary

• Single-chip solution integrating analog transceivers, filters, and amplifiers for direct voice signal storage.
• Automatic power-down mode reduces standby current to 0.5 µA after each cycle.
• Push-button interface supports both edge-activated and level-activated playback modes.
• Patented Multi-Level Storage technology enables high-quality natural voice reproduction without synthetic effects.

Applications

• Single-message or multi-message voice prompts
• Toy and novelty items requiring voice interaction
• Industrial control systems with voice feedback
• Security alarms and monitoring devices

Procurement Notes

Verify the manufacturer designation, as the ISD1200 series was originally developed by Winbond. Confirm the specific package type (PDIP or SOIC) required for your design, as availability may vary between packaged units and die forms. Ensure the voltage supply matches the +5V specification and that the temperature range meets commercial requirements.

Selection Notes

Select the ISD1210S when a 10-second duration at 6.4 kHz sampling rate is sufficient for the application. Choose this part over the ISD1212 if higher speech quality is prioritized over longer recording time. Consider the addressing capabilities if multiple distinct messages need to be stored and played back sequentially within the same chip.

Part Context

The ISD1210S belongs to the ISD1200 series of ChipCorder devices, which also includes the 12-second ISD1212 variant. These devices utilize Winbond's proprietary Multi-Level Storage technology to store audio directly in EEPROM cells. The series is designed for simple push-button operation without the need for external microcontrollers or development systems.

Replacement Considerations

The ISD1212 serves as a functional alternative within the same series, offering 12 seconds of recording time at a lower 5.3 kHz sampling rate. Other members of the ISD1200 series may offer different durations or operational modes but share similar interface characteristics.

FAQ

How does the ISD1210S handle power consumption during idle states?

The device automatically enters a low-power standby mode after completing a record or playback cycle, consuming a typical standby current of only 0.5 µA.

Can the ISD1210S play back multiple distinct messages?

Yes, the device has eight address inputs (A0-A7) that allow for fully addressable storage, enabling the recording and playback of up to 80 distinct message segments.

Recordings are stored in nonvolatile memory and typically retain data for up to 100 years without power.
