MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
8MB Synchronous Fast Static
RAM Module
The MCM72F10 (2MB) is configured as 1M x 72 bits. It is packaged in a
168–pin dual–in–line memory module DIMM. The module uses Motorola’s 3.3 V,
256K x 18 bit flow–through BurstRAMs.
Address (A), data inputs (DQ, DP), and all control signals except output enable
(G) are clock (K) controlled through positive–edge–triggered noninverting
registers.
Write cycles are internally self–timed and initiated by the rising edge of the
clock (K) input. This feature provides increased timing flexibility for incoming
signals. Synchronous byte write (W) allows writes to either individual bytes or to
both bytes.
• Single 3.3 V + 10%, – 5% Power Supply
• Plug and Pin Compatibility with 1MB, 2MB, and 4MB
• Multiple Clock Pins for Reduced Loading
• All Inputs and Outputs are LVTTL Compatible
• Byte Write Capability
• Fast SRAM Access Times: 8/9/12 ns
• High Quality Multi–Layer FR4 PWB With Separate Power and Ground
Planes
• Amp Connector, Part Number: 390064–4
• 168–Pin DIMM Module

NOTES:
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are
exceeded. Functional operation should be restricted to RECOMMENDED OPER-
ATING CONDITIONS. Exposure to higher than recommended voltages for extended
periods of time could affect device reliability.
2. This is a steady–state DC parameter that is in effect after the power supply has
achieved its nominal operating level. Power sequencing can not be controlled and
is not allowed.
3. Power dissipation capability is dependent upon package characteristics and use
environment. See Package Thermal Characteristics.
This device contains circuitry to protect the
inputs against damage due to high static volt-
ages or electric fields; however, it is advised that
normal precautions be taken to avoid application
of any voltage higher than maximum rated volt-
ages to this high–impedance circuit.
