Rohm Semiconductor has a family of low power audio decoders with integrated mask ROM or flash memory and a 1W monaural speaker amplifier.

The ML22(Q)34x Playback IC is designed to support both speech and sound output in a single chip.

An internal event input system means that audio playback can be started with a sensor or switch event without relying on an additional microcontroller.

It also allows for the control of peripheral circuits such as LEDs.

The family comes in two different versions offering a choice of features like different memory types, speech ROM capacity (640kbit or 896kbit), playback time (20 or 35 seconds) and operating temperature ranges (from -40 to 85° C).
