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.

The major differences between the MSM6595A and MSM6595 are shown below.

PIN DESCRIPTIONS

		Pin				Symbol	Type		Description
	QFJ	SOP	DIP	SSOP
9		12	9	15		VDD	—		Power supply pin. Insert a bypass capacitor of 0.1 mF or more between this
									pin and the GND pin.
18		24	18	30		GND	—		Ground pin
									(SERIAL ADDRESS) This pin inputs the starting X address of a read operation.
6		9	6	12		SADX	I		Addressing in units of 1024 words is possible. The 1024-word address data
									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.
1		1	1	1		SADY	I		Addressing in units of 1024 words is possible. The 1024-word address data
									can be input as 10-bit (AY0 - AY9) serial data via the SADY pin.
7		10	7	13		SASX	I		(SERIAL ADDRESS STROBE) This is the clock input pin which is used to store
									the serial address data of the X address into the device's internal register.
2		2	2	2		SASY	I		(SERIAL ADDRESS STROBE) This is the clock input pin to store the serial
									address data of the Y address into the device's internal register.
									(ADDRESS TRANSFER STROBE) This is the input pin for loading the serial
8		11	8	14		TAS	I		address data into the internal address counter.
									The X and Y addresses are stored at the falling edge of TAS.
									(READ CLOCK) This is the clock input pin for reading information out of the data
13		15	13	18		RDCK	I		register. Internal operation starts at the falling edge of RDCK. The information
									in the data register is output on the DOUT pin. The internal address counter is
									automatically incremented at the falling edge of RDCK.
									(DATA OUT) The data output pin is always kept in a high-impedance state when
17		22	17	28		DOUT	O		RDCK or CS is kept at "H". This pin reflects the "H" or "L" level data being read,
									and the current data is held until RDCK is asserted High.
4		4	4	5		CS	I		(CHIP SELECT) Setting this pin to "H" disables all input and output pins. This pin
									enables parallel use of multiple serial voice ROMs by connecting the data output pins.
10		13	10	16		TEST	I		Pins for testing. Apply a "L" level to the TEST pin and "H" level to the TEST pin.
3		3	3	3		TEST
16		21	16	27		TESTO1	O		Pins for testing. Leave these pins open.
