Automotive-grade (Flash Memory, MaskROM)
The Automotive-grade Speech Synthesis LSI guarantees an operating temperature of +105°C with 1 to 4 channel mixing and a built-in speaker amplifier. AEC-Q100 qualified products can be provided.
As the fail-safe function, it is equipped with functions necessary for in-vehicle use such as detection of internal temperature of LSI, detection of voltage drop of power supply, and detection of command transfer error.
Long Playback (Flash Memory,P2ROM™)
Long Playback Speech Synthesis LSI ML22Q6xx has a large-capacity 4Mbit to 32Mbit flash memory with rewritable voice data.
The ML228xx and ML227xx incorporate LAPIS Technology's proprietary memory P2ROM capable of short TAT from 2Mbit to 32Mbit.
Both are ideal for long playback such as voice operation guidance.
Short Playback (Flash Memory, MaskROM)
Short playback Speech Synthesis LSI has a built-in ROM of 692Kbit to 4Mbit.
Flash memory products and Mask products are pin compatible, and their characteristics are completely compatible. Developed with flash memory products and mass-produced with mask products, it is also possible to ship flash memory blank (unwritten).
Supports External Memory
External memory compatible speech synthesis LSIs ML226xx and ML224xx can connect up to 128Mbit serial memory externally.
Ideal for long audio playback.
