ISD1210P

Overview

The ISD1210P is a single-chip voice record/playback device from the ISD1200 series, providing 10 seconds of recording duration. It operates on a single +5V supply and features an on-chip oscillator, microphone preamplifier, automatic gain control, and speaker amplifier. The device utilizes Multi-Level Storage technology to store voice signals directly in nonvolatile memory cells, ensuring zero-power message storage with 100-year retention and 100,000 record cycles. It supports edge- or level-activated playback via push-button interface and includes fully addressable segments for multiple messages.

Feature Summary

• Single-chip solution integrating analog transceivers, filters, and nonvolatile memory for direct voice storage without synthetic effects.
• Automatic power-down mode reduces standby current to 0.5 µA typical after each cycle.
• Fully addressable architecture allows handling of multiple distinct messages using eight address inputs.
• Push-button interface supports both edge-activated (PLAYE) and level-activated (PLAYL) playback initiation.

Applications

• Single-message or multi-message paging systems
• Voice prompts for industrial equipment or appliances
• Security alarm announcements
• Educational toys with recorded speech

Procurement Notes

Verify the manufacturer designation, as the datasheet identifies Winbond as the producer while the prompt specifies Nuvoton. Confirm the package type availability, as the ISD1200 series is offered in PDIP, SOIC, and die formats. Ensure the specific part number suffix corresponds to the required packaging and temperature range before ordering.

Selection Notes

Select the ISD1210P when a fixed 10-second recording duration at a 6.4 kHz sampling rate is required. Choose this model over the ISD1212 if lower power consumption during operation is prioritized, as the higher sampling rate of the ISD1210 may impact current draw. Verify that the application environment stays within the commercial temperature range of 0°C to 70°C for packaged units.

Part Context

The ISD1210P belongs to the ISD1200 series of ChipCorder devices, which also includes the ISD1212 for 12-second durations. These devices are designed for simple, low-cost voice messaging applications requiring high-quality natural audio reproduction. The series leverages patented Multi-Level Storage technology to eliminate the need for external microcontrollers or complex digital signal processing circuits.

Replacement Considerations

The ISD1212 is a compatible alternative within the same series offering 12 seconds of duration. For longer recording times, consider the ISD1400 series. Direct pin-to-pin replacements should be verified against the specific package type (PDIP/SOIC) and operating temperature requirements.

FAQ

How does the ISD1210P handle automatic power management?

The device automatically enters a low-power standby mode consuming typically 0.5 µA immediately after completing a record or playback cycle. This occurs whether the cycle finishes naturally or is terminated by pulling the REC signal HIGH.

What is the function of the AGC pin?

The AGC pin dynamically adjusts the preamplifier gain to compensate for varying microphone input levels. Connecting an external capacitor and resistor network to this pin allows tuning of the attack and release times for optimal audio recording quality.

Can the ISD1210P play back multiple messages sequentially?

Yes, by utilizing the A4 Operational Mode (Consecutive Addressing), the device can inhibit the address pointer reset, allowing messages to be recorded or played back consecutively across different address segments.
