256K x 4 Bit Synchronous Static
RAM with Latched Outputs
The MCM67F804 is a 1,048,576 bit static random access memory organized as
262,144 x 4 bits. This device is fabricated using Motorola's high-performance
silicon-gate BiCMOS technology. It features separate TTL input and output buffers,
which are fully I/O compatible at 3.3 V, and incorporates input registers and output
latches on board with high speed SRAM.
The synchronous design allows for precise cycle control with the use of an exter-
nal single clock (K). The Addresses (AO - A17), Data Input (DO - D3), Data Output
(00 - 03), Write-Enable (W), and Chip Enable (E), are registered in on the rising
edge of Clock (K).
The MCM67F804 is available in a 400 mil, 32-lead surface-mount SOJ package.
• Single 5 V ± 10% Power Supply
• Fast Cycle Times: 12115 ns Max
• Single Clock Operation
• TTL Input and Output Levels (3.3 V I/O Compatible)
• Address, Data Input, E, WRegisters on Chip
• Transparent Output Latches
