MOTOROLA SEMICONDUCTOR TECHNICAL DATA Product Preview 128K x 36 and 256K x 18 Bit Pipelined BurstRAM Synchronous Fast Static RAM The MCM63P736 and MCM63P818 are 4M bit synchronous fast static RAMs designed to provide a burstable, high performance, secondary cache for the PowerPC and other high performance microprocessors. The MCM63P736 is organized as 128K words of 36 bits each and the MCM63P818 is organized as 256K words of 18 bits each. These devices integrate input registers, an output register, a 2-bit address counter, and high speed SRAM onto a single monolithic circuit for reduced parts count in cache data RAM applications. Synchronous design allows precise cycle control with the use of an external clock (K). Addresses (SA), data inputs (DQx), and all control signals except output enable (G), sleep mode (ZZ), and linear burst order (LBO) are clock (K) controlled through positive-edge-triggered noninverting registers. Bursts can be initiated with either ADSP or ADSC input pins. Subsequent burst addresses can be generated internally by the MCM63P736 and MCM63P818 (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 off-chip write pulse generation and provides increased timing flexibility for incoming signals. Synchronous byte write (SBx), synchronous global write (SGW), and synchronous write enable (SW) are provided to allow writes to either individual bytes or to all bytes. The bytes are designated as "a", "b", etc. SBa controls DQa, SBb controls DQb, etc. 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, pipelined SRAMs output data is temporarily stored by an edge-triggered output register and then released to the output buffers at the next rising edge of clock (K). The MCM63P736 and MCM63P818 operate 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 standard JESD8-5 compatible.

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 signal and is not sampled by the clock K. G drives the bus immediately (tGLQX) following G going low. 4. On write cycles that follow 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.

Write is defined as either any SBx and SW low or SGW is low. Chip Enable is defined as SE1 low, SE2 high, and SE3 low whenever ADSP or ADSC is asserted. 2. All read and write cycle timings are referenced from K or G. 3. In order to reduce test correlation issues and to reduce the effects of application specific input edge rate variations on correlation between data sheet parameters and actual system performance, FSRAM AC parametric specifications are always specified at VDDQ/2. In some design exercises, it is desirable to evaluate timing using other reference levels. Since the maximum test input edge rate is known and is given in the AC Test Conditions section of the data sheet as 1 V/ns, one can easily interpolate timing values to other reference levels. 4. This parameter is sampled and not 100% tested. 5. Measured at 200 mV from steady state. MOTOROLA FAST SRAM MCM63P736*MCM63P818 13 OUTPUT Z0 = 50 RL = 50 1.25 V Figure 2.

It allows the system designer to place the RAM in the lowest possible power condition by asserting ZZ. The sleep mode timing diagram shows the different modes of operation: Normal Operation, No READ/WRITE Allowed, and Sleep Mode. Each mode has its own set of constraints and conditions that are allowed. Normal Operation: All inputs must meet setup and hold times prior to sleep and t ZZREC nanoseconds after recovering from sleep. Clock (K) must also meet cycle, high, and low times during these periods. Two cycles prior to sleep, initiation of either a read or write operation is not allowed. No READ/WRITE: During the period of time just prior to sleep and during recovery from sleep, the assertion of either ADSC, ADSP, or any write signal is not allowed. If a write operation occurs during these periods, the memory array may be corrupted. Validity of data out from the RAM can not be guaranteed immediately after ZZ is asserted (prior to being in sleep). Sleep Mode: The RAM automatically deselects itself. The RAM disconnects its internal clock buffer. The external clock may continue to run without impacting the RAMs sleep current (IZZ). All inputs are allowed to toggle -- the RAM will not be selected and perform any reads or writes. However, if inputs toggle, the IZZ (max) specification will not be met. NON-BURST SYNCHRONOUS OPERATION Although this BurstRAM has been designed for PowerPC- and Pentium-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 interface can make use of the MCM63P736 and MCM63P818. The burst counter feature of the BurstRAMs can be disabled, and the SRAMs can be configured to act upon a continuous stream of addresses. See Figure 6.
