3-Mbit Serial Voice ROM
GENERAL DESCRIPTION
The MSM6597A is a MSM6597 short TAT process version.
The MSM6597A is a serial voice ROM with a 1,048,576-word
￥
1-bit
￥
3-bank configuration.
The MSM6597A 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. Banks are switched with
CS1
,
CS2
, and
CS3
.
A read and playback device with predetermined messages can easily be configured by storing voice
data into the MSM6597A and by combining it with one of Oki's recording and playback ICs and with
one of Oki's serial registers.
A serial register is required to drive the MSM6597A when used with the MSM6388 or MSM6588. (The
MSM6597A does not operate without a serial register.)
The major differences between the MSM6597A and MSM6597 are shown below.
