2-Channel Mixing Oki ADPCM Algorithm-Based Speech Synthesis LSI

This document contains minimum specifications. For full specifications, please contact your nearest Oki office or

representative.

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.

• ML22Q54

The ML22Q54 is a speech synthesis device with a 4-Mbit flash memory built in. The voice data can be easily

written to the flash memory using a special tool. The on-chip flash memory product is suitable for the diversified

low volume production or short delivery time applications that the on-chip mask ROM product cannot support.

The ML22Q54 is most suitable for evaluation because the circuit configuration is the same as the on-chip mask

ROM product.

A combination of fixed and variable messages can be written because it is easy to write to the built-in flash

memory. It is also possible to store and read data, other than voice, to/from an area in the flash memory not used

as voice data.
