Semiconductor MSM6597A-xxx
Semiconductor 3-Mbit Serial Voice ROM
This version: Feb. 1999 MSM6597A-xxx Previous version: May. 1997
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. MSM6597A DC Characteristics

PIN DESCRIPTIONS
Pin SOP SSOP Symbol Type
Description Power supply pin. Insert a bypass capacitor of 0.1 mF or more between this pin and the GND pin. Ground pin (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 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 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 the serial address data of the X address into the device's internal register. (SERIAL ADDRESS STROBE) This is the clock input pin which is used 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 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 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 by 1 at the falling edge of RDCK. (DATA OUT) The data output pin is always kept in a high-impedance state when CS1, CS2, and CS3 are all kept "H" or when RDCK is kept "H". This pin reflects the "H" or "L" level data being read, and the current data is hold until RDCH is asserted High. (CHIP SELECT) When either CS1, CS2, or CS3 is "L", bank 1, bank 2, or bank 3 is selected, respectively. Setting all three signals "H" disables all input and output pins. These pins enable parallel use of multiple serial voice ROMs by connecting the data output pins. Pin for testing. Apply "L" level. Pins for testing. Leave these pins open.
