ML22Q294
Internal Memory Type

ML22Q274/ML22Q284/ML22Q294 is a speech synthesis LSI supporting an in-vehicle quality that incorporates Flash memory for storing sound code data.
ML22Q274 can be controlled the clock synchronization serial interface, ML22Q284 can be controlled with a standalone interface, and ML22Q294 can be controlled with a I2C interface.
By integrating D-class speaker amplifier, solution required for sound output is made possible with single chip.
