256K x 4 Bit Synchronous Static
RAM with Registered Outputs
The Motorola MCM67P804 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 SiCMOS technology. It features separate TIL input and
output buffers, which are fully 1/0 compatible at 3.3 V, and incorporates input and
output registers 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 - 03), Data Output
(00 - 03), Write Enable (W), and Chip Enable (E) are registered in on the rising
edge of Clock (K).
The MCM67P804 is available in a 400 mil, 32-lead surface-mount SOJ package.
• Single 5 V ± 10% Power Supply
• Fast Cycle Times: 10/12 ns Max
• Single Clock Operation
• TIL Input and Output Levels (3.3 V 1/0 Compatible)
• Address, Data Input, E, W, Registers on Chip
• 100 MHz Maximum Clock Cycle Time
• Self Timed Write
• High Output Drive Capability: 85 pFIOutput at Rated Access Time
