GENERAL DESCRIPTION
The MSM6596A is the shorter-TAT processing version of the MSM6596. The MSM6596A is a serial voice ROM with a 1,048,576-word ¥ 1-bit ¥ 2-bank configuration. The MSM6596A 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 and CS2. A read and playback device with predetermined messages can easily be configured by storing thevoice data into the MSM6596A and combining it with one of OKI's recording and playback ICs and serial register IC.
A serial register is required to drive the MSM6596A by the MSM6388 or MSM6588. (The MSM6596A does not operate without a serial register.) The major functional differences between the MSM6596A and MSM6596 are shown below.
