Automotive-grade  (Flash Memory, MaskROM)
ML22Q5xx、ML22Q3xx、ML22Q2xx、ML225xx

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™)
ML22Q6xx、ML228xx、ML227xx

Long Playback Speech Synthesis LSI ML22Q6xx has a large-capacity 4Mbit to 32Mbit flash memory with rewritable sound data.
The ML228xx and ML227xx incorporate LAPIS Technology's proprietary memory P2ROM capable of short TAT from 4Mbit to 16Mbit.
Both are ideal for long playback such as voice operation guidance.

Short Playback (Flash Memory, MaskROM)
ML22Q56x、ML22Q3xx、ML22Q2xx、ML2256x、ML223xx

Short playback Speech Synthesis LSI has a built-in ROM of 692Kbit to 4Mbit,and speech playback is possible simply by inputting a simple command from the MCU.
This LSI prepares various input interfaces to meet the needs of a wide range of customers.
The speech playback function can be easily realized by simply adding this LSI to the customer's system.

Supports External Memory
