描述 Description

DESCRIPTION
The MSM54V25632A is a synchronous graphics random access memory organized as 128 K words x 32 bits x 2 banks.
This device can operate up to 100 MHz by using synchronous interface. In addition, it has 8-column Block Write function and Write per bit function which improves performance in graphics systems.FEATURES
• 131,072 words x 32 bits x 2 banks memory
• Single 3.3 V ±0.3 V power supply
• LVTTL compatible inputs and outputs
• All input signals are latched at rising edge of system clock
• Auto precharge and controlled precharge
• Internal pipelined operation: column address can be changed every clock cycle
• Dual internal banks controlled by A9 (Bank Address: BA)
• Independent byte operation via DQM0 to DQM3
• 8-column Block Write function
• Persistent write per bit function
• Programmable burst sequence (Sequential/Interleave)
• Programmable burst length (1, 2, 4, 8 and full page)
• Programmable CAS latency (1, 2 and 3)
• Burst stop function (full-page burst)
• Power Down operation and Clock Suspend operation
• Auto refresh and self refresh capability
• 1,024 refresh cycles/16 ms
• Package:
      100-pin plastic QFP (QFP100-P-1420-0.65-BK4) (Product : MSM54V25632A-xxAGBK4)
