Overview
The ISD5104SYR is a single-chip voice record/playback solution from the ISD5100 ChipCorder series, manufactured by Nuvoton Technology Corporation. It provides 2 to 4 minutes of recording duration and features up to 1 Mb of storage capacity for dual analog and digital data. The device operates on a supply voltage of +2.7V to +3.3V and supports 2.0V and 3.0V interface logic. It utilizes an I2C serial interface for control and data transfer, with typical operating currents of 15 mA during playback and 30 mA during recording. Standby current is typically 1 µA. The component is housed in a 28-lead SOIC package.
Feature Summary
- Dual storage capability for both analog voice messages and digital system data within a single chip.
- Integrated audio processing including automatic gain control (AGC), power amplifier, and volume control.
- Supports simplex and duplex conversation recording and playback via dedicated microphone and auxiliary inputs.
- Controlled via standard I2C serial interface requiring only two control lines for address and command operations.
Applications
- Cellular phones and portable communication devices
- Automotive communications systems
- GPS and navigation systems
Procurement Notes
Verify the specific suffix 'SYR' against the official datasheet to confirm tape and reel packaging and temperature grade. Ensure the host system voltage aligns with the specified 2.7V to 3.3V range. Confirm I2C address pin configurations match the application design requirements.
Selection Notes
Select this model when a recording duration between 2 and 4 minutes is required. Consider the ISD5102 or ISD5108 if shorter or longer durations are needed respectively. Verify that the available 1 Mb memory space accommodates both the desired analog message length and any necessary digital data storage.
Part Context
The ISD5104 is part of the ISD5100 series, which enhances the previous ISD5000 architecture by adding I2C control and digital memory capabilities. This series integrates sampling clocks, filters, and multi-level storage arrays to eliminate external circuitry for voice messaging applications.
Replacement Considerations
ISD5104SOI is the SOIC variant without the R suffix. ISD5104PDIP is the PDIP package variant. Check datasheet section 12 for exact ordering codes and suffix definitions regarding packaging and temperature ranges.
