MSM6691
DRAM Interface IC
MSM6691
GENERAL DESCRIPTION
DRAMs can be used for voice storage by connecting the MSM6691 with OKI's integrate R/W
(Read/Write) ICs, the MSM6388, and the MSM6588. The MSM6691 translates the signals
associated with the dedicated serial register interface of the MSM6388 and MSM6588 driver
interface when used in a stand-alone mode.
FEATURES
• DRAM (¥ 1-bit configuration)
• 1-Mbit DRAM (M 51100A, M511001A) : Four units can be used.
• 4-Mbit DRAM (M 514100A, M514101A) : Four units can be used.
• Power voltage : 5V single
• Built-in refresh circuit (RAS only refresh)
• Oscillation frequency : 8MHz (during refresh)
• Sampling frequency
• 4 kHz to 32 kHz when MSM6388 is connected.
• 4 kHz to 16 kHz when MSM6588 is connected.
• Package : 44-pin plastic QFP (QFP44-P-910-2K) (Product name : MSM6691GS-2K)
