Description

The ML22Q54 is a 2-channel mixing speech synthesis device with an on-chip voice data (i.e., phrases) storing mask ROM and a flash memory. Besides playing the built-in voice data, this device can output voice data that is input from outside the device. This ML22Q54 allows to select the playback method from the 8-bit PCM, non-linear 8-bit PCM, 16-bit PCM, 2-bit ADPCM2, and 4-bit ADPCM2 algorithms. And the sound volume is adjustable as well.

The ML22Q54 incorporates a 14-bit D/A converter, low-pass filter, and 1-bit DAC (PWM output). It is easy to configure a speech synthesizer by externally connecting a power amplifier and a CPU to the ML2250 family.

The ML22Q54 line-up includes 2 types of products: with on-chip mask ROM, and with on-chip flash memory.
