Audio Special Purpose datasheet and documents for BU6929FV-E2
Audio Special Purpose Overview
The BU6929FV-E2 is a voice synthesis IC from ROHM Semiconductor designed for high-quality audio processing. It features an internal serial flash memory to store voice data, eliminating the need for external storage components. The device operates on a single power supply (2.7 V to 3.6 V) and utilizes an SPI interface for communication with a host microcontroller. Designed for surface-mount assembly, it is housed in a compact 28-pin SSOP package.
Audio Special Purpose Feature Summary
- Integrated serial flash memory for voice data storage
- SPI interface for simple host controller connection
- Compact 28-pin SSOP surface-mount package
- Single power supply operation (2.7 V to 3.6 V)
- Low power consumption (10 µA typical)
Audio Special Purpose Applications
- Voice guidance systems for home appliances
- Announcement modules for industrial equipment
- Interactive toys and educational devices
- HIFI audio synthesis interfaces
Audio Special Purpose Procurement Notes
This component is currently listed as End-of-Life (EOL) / Discontinued by ROHM Semiconductor. Distributors may have limited stock or offer substitute options. Verify the specific suffix 'E2' against the manufacturer's current datasheet to confirm RoHS compliance status. Ensure that any replacement parts are validated for pin compatibility and electrical specifications.
Audio Special Purpose Selection Notes
Select this component when a complete voice solution without external memory is required. The SPI interface simplifies firmware development compared to parallel interfaces. Consider the 28-pin SSOP package dimensions if board space is constrained. Verify that the internal flash capacity meets the duration requirements of the desired voice messages. Note the maximum clock frequency of 16.384 MHz and resolution of 16 bits.
Audio Special Purpose Part Context
This part belongs to ROHM's audio special purpose IC lineup, specifically designed for voice synthesis. It integrates the digital signal processing engine and non-volatile storage into a single chip. This integration reduces bill-of-materials count and simplifies PCB layout compared to discrete solutions using separate DSP and flash memory chips.
