Oki Electric Industry 

ML2216-XXX/ML22P16

Oki ADPCM2 Algorithm-Based Speech Synthesis LSI

FEDL2216DIGEST-04

Issue Date: Nov. 16, 2009

GENERAL DESCRIPTION

The ML2216-XXX is speech synthesis device with a 8Mbit P2ROM built-in.

The ML2216-XXX incorporates ADPCM2 decoder, 12-bit D/A converter, and low-pass filter. Moreover, the

monophonic speaker amplifier for driving a direct speaker is built in.

The ML2216-XXX carried out all functions required for a voice response circuit to one chip. For this reason,

inclusion to small and pocket equipment became still easier.

ML2216-xxx serves as write-in shipment.

ML22P16 is speech synthesis device with 8M bit OTP memory built-in. User is able to program a device one time

by using exclusive tool.
