GENERAL DESCRIPTION
The ML2250 family 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 ML2250 family 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 ML2250 family 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 ML2250 family line-up includes 2 types of products: with on-chip mask ROM, and with on-chip flash memory.● ML2252/54-XXX This is a CMOS single chip speech synthesis device with an on-chip mask ROM. Products with 2 types of mask ROMs are available in the ML2250 family depending upon the total playback time length.
