1-Mbit Serial Voice ROM
This version: Feb. 1999
MSM6595A-xxx
Previous version: May. 1997
GENERAL DESCRIPTION
The MSM6595A is a MSM6595 short TAT process version.
The MSM6595A is a serial voice ROM with a 1,048,576-word
樓
1-bit configuration.
The MSM6595A has a built-in internal address-generating circuit. A single, external clock input
allows continuous, serial read operations. The internal addresses are automatically incremented by
1 by read operation. 1024 words in X direction and 1024 words in Y direction can be addressed by
inputting external serial addresses. A read and playback device with predetermined messages can
easily be configured by storing voice data into the MSM6595A and by combining it with one of Oki's
recording and playback ICs and a serial register IC.
A serial register is required to drive the MSM6595A by the MSM6388 or MSM6588. (The MSM6595A
does not operate without a serial register.)
The major differences between the MSM6595A and MSM6595 are shown below.
