Description

The MSM6597A-xxx 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 of MSM6597A-xxx 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 ad-dresses. Banks of MSM6597A-xxx 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 pl-ayback ICs and with one of Oki's serial registers.

A serial register MSM6597A-xxx is required to drive the MSM6597A when used with the MSM6388 or MSM6588. (The MSM6597A does not operate without a serial register.)
