MCM69F819
256K x 18 Bit Flow–Through
BurstRAM Synchronous
Fast Static RAM
The MCM69F819 is a 4M bit synchronous fast static RAM designed to provide
a burstable, high performance, secondary cache for the PowerPC and other
high performance microprocessors. It is organized as 256K words of 18 bits
each. This device integrates input registers, a 2–bit address counter, and high
speed SRAM onto a single monolithic circuit for reduced parts count in cache
dataRAMapplications. Synchronousdesignallowsprecisecyclecontrolwiththe
use of an external clock (K).
ZP PACKAGE
PBGA
CASE 999–02
Addresses (SA), data inputs (DQx), and all control signals except output
enable(G) and linear burst order (LBO) are clock (K) controlled through positive
edge–triggered noninverting registers.
TQ PACKAGE
TQFP
CASE 983A–01
Bursts can be initiated with either ADSP or ADSC input pins. Subsequent burst
addresses can be generated internally by the MCM69F819 (burst sequence
operates in linear or interleaved mode dependent upon the state of LBO) and
controlled by the burst address advance (ADV) input pin.
Write cycles are internally self–timed and are initiated by the rising edge of the
clock (K) input. This feature eliminates complex of–chip write pulse generation
and provides increased timing flexibility for incoming signals.
Synchronous byte write (SBx), synchronous global write (SGW), and synchro-
nous write enable (SW) are provided to allow writes to either individual bytes or
to all bytes. The two bytes are designated as “a” and “b”. SBa controls DQa and
SBb controls DQb. Individual bytes are written if the selected byte writes SBx are
asserted with SW. All bytes are written if either SGW is asserted or if all SBx and
SW are asserted.
For read cycles, a flow–through SRAM allows output data to simply flow freely
from the memory array.
The MCM69F819 operates from a 3.3 V core power supply and all outputs
operate on a 2.5 V or 3.3 V power supply. All inputs and outputs are JEDEC stan-
dard JESD8–5 compatible.

1. X = Don’t Care. 1 = logic high. 0 = logic low.
2. Write is defined as either 1) any SBx and SW low or 2) SGW is low.
3. G is an asynchronous signaand is not sampled by the clock K. G drives the bus immediately (t
) following G going low.
GLQX
4. On write cycles that follw read cycles, G must be negated prior to the start of the write cycle to ensure proper write data setup times. G must
also remain negated at the completion of the write cycle to ensure proper write data hold times.
5. This read assumes the RAM was previously deselected.

ABSOLUTE MAXIMUM RATINGS (See Note 1)
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 maxi-

1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are
exceeded. Functional operation should be restricted to RECOMMENDED OPER-
ATING CONDITIONS. Exposuretohigherthanrecommendedvoltagesforextended
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 is not necessary.
3. Power dissipation capability is dependent upon package characteristics and use

APPLICATION INFORMATION
STOP CLOCK OPERATION
operation for all three stop clock modes, stop read, stop
write, and stop deselect:
To achieve the lowest power operation for all three stop
clock modes, stop read, stop write, and stop deselect:
In the stop clock mode of operation, the SRAM will hold all
state and data values even though the clock is not running
(full static operation). The SRAM design allows the clock to
start with ADSP and ADSC, and stops the clock after the last
write data is latched, or the last read data is driven out.
When starting and stopping the clock, the AC clock timing
and parametrics must be strictly maintained. For example,
clock pulse width and edge rates must be guaranteed when
starting and stopping the clocks.To achieve the lowest power
•
•
Force the clock to a low state.
Force the control signals to an inactive state (this
guarantees any potential source of noise on the clock
input will not start an unplanned on activity).
•
Force the address inputs to a low state (V ), preferably
IL
< 0.2 V.

Although this BurstRAM has been designed for PowerPC–
based and other high end MPU–based systems, these
SRAMs can be used in other high speed L2 cache or
memory applications that do not require the burst address
feature. Most L2 caches designed with a synchronous inter-
face can make use of the MCM69F819. The burst counter
feature of the BurstRAM can be disabled, and the SRAM can
be configured to act upon a continuous stream of addresses.
