LAPIS ML22Q321
The ML22321/ML22Q321, which include mask ROM and Flash memory for storing speech data, respectively, are speech synthesis LSIs which can control speech playback utilizing a serial interface. It includes speaker amplifier and 16bit DA Converter, so it is possible to have high quality sound and solution for playback with 1chip. It was developed by “Ky’s”.GENERAL DESCRIPTION
