29-07-2020 | Lapis Semiconductor | Automotive Technologies

LAPIS Semiconductor, a ROHM Group Company, launched the automotive speech synthesis ICs, ML2253x series, optimised for audible notifications and sound effects in ADAS and AVAS.


The Speech Synthesis ICs offer an innovative technology as well as features for higher safety, improved flexibility on application level, therefore decreasing overall system costs and simplifying the hardware and software design.


“ROHM is embracing the growing market and increased safety demand by the auto makers for reliable voice and sound generation systems,” says Stefan Drouzas, senior application marketing manager at ROHM Semiconductor GmbH.


Employing a state-of-the-art compression method (HQ-ADPCM), the series offers superior audio playback with reduced memory usage for storing audio data.


To enhance the versatility of development from day one and beyond shipment of the finished product, the memory content can be updated through the main MCU, when connected to a communication network (IoT).
