MSM6595A-xxx
1-Mbit Serial Voice ROM
GENERAL DESCRIPTION
The MSM6595A is a MSM6595 short TAT process version.
The MSM6595A is a serial voice ROM with a 1,048,576-word ¥ 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.

(SERIAL ADDRESS) This pin inputs the starting X address of a read operation.
Addressing in units of 1024 words is possible. The 1024-word address data
I
can be input as 10-bit (AX0 - AX9) serial data via the SADX pin.
(SERIAL ADDRESS) This pin inputs the starting Y address of a read operation.
Addressing in units of 1024 words is possible. The 1024-word address data
I
can be input as 10-bit (AY0 - AY9) serial data via the SADY pin.
(SERIAL ADDRESS STROBE) This is the clock input pin which is used to store
I
the serial address data of the X address into the device's internal register.
(SERIAL ADDRESS STROBE) This is the clock input pin to store the serial
ISASY
address data of the Y address into the device's internal register.
(ADDRESS TRANSFER STROBE) This is the input pin for loading the serial
address data into the internal address counter.
