MCM63P733A
128K x 32 Bit Pipelined BurstRAM Synchronous Fast Static RAM
The MCM63P733A is a 4M-bit synchronous fast static RAM designed to provide a burstable, high performance, secondary cache for the PowerPCTM and other high performance microprocessors. It is organized as 128K words of 32 bits each, fabricated with high performance silicon gate CMOS technology. This device integrates 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). CMOS circuitry reduces the overall power consumption of the integrated functions for greater reliability. 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. Bursts can be initiated with either ADSP or ADSC input pins. Subsequent burst addresses can be generated internally by the MCM63P733A (burst sequence operates in linear or interleaved mode dependent upon 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 four bytes are designated as "a", "b", "c", and "d". 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 MCM63P733A 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 standard JESD8-5 compatible. * MCM63P733A-133 = 4 ns Access/7.5 ns Cycle (133 MHz) MCM63P733A-117 = 4.2 ns Access/8.5 ns Cycle (117 MHz) MCM63P733A-100 = 4.5 ns Access/10 ns Cycle (100 MHz) MCM63P733A-90 = 5 ns Access/11 ns Cycle (90 MHz) * 3.3 V + 10% / - 5% Core, Power Supply, 2.5 V or 3.3 V I/O Supply * ADSP, ADSC, and ADV Burst Control Pins * Selectable Burst Sequencing Order (Linear/Interleaved) * Internally Self-Timed Write Cycle * Byte Write and Global Write Control * Single-Cycle Deselect * Sleep Mode (ZZ) * 100-Pin TQFP Package

Asynchronous Output Enable Input. Clock: This signal registers the address, data in, and all control signals except G, LBO, and ZZ. Linear Burst Order Input: This pin may be left floating; it will default as interleaved. Low -- linear burst counter (68K/PowerPC). High -- interleaved burst counter (486/i960/Pentium). Synchronous Address Inputs: These inputs are registered and must meet setup and hold times. Synchronous Address Inputs: These pins must be wired to the two LSBs of the address bus for proper burst operation. These inputs are registered and must meet setup and hold times. Synchronous Byte Write Inputs: "x" refers to the byte being written (byte a, b, c, d). SGW overrides SBx. Synchronous Chip Enable: Active low to enable chip. Negated high -- blocks ADSP or deselects chip when ADSC is asserted. Synchronous Chip Enable: Active high for depth expansion. Synchronous Chip Enable: Active low for depth expansion. Synchronous Global Write: This signal writes all bytes regardless of the status of the SBx and SW signals. If only byte write signals SBx are being used, tie this pin high. Synchronous Write: This signal writes only those bytes that have been selected using the byte write SBx pins. If only byte write signals SBx are being used, tie this pin low. Sleep Mode: This active high asynchronous signal places the RAM into the lowest power mode. The ZZ pin disables the RAMs internal clock when placed in this mode. When ZZ is negated, the RAM remains in low power mode until it is commanded to READ or WRITE. Data integrity is maintained upon returning to normal operation. Core Power Supply. I/O Power Supply.

NOTES: 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 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.

NOTES: 1. 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. G is a don't care after write cycle begins. To prevent bus contention, G should be negated prior to start of write cycle. 4. 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. 5. This parameter is sampled and not 100% tested. 6. Measured at 200 mV from steady state.

SLEEP MODE TIMING
IN SLEEP MODE
NO READS OR WRITES ALLOWED NORMAL OPERATION
APPLICATION INFORMATION
SLEEP MODE A sleep mode feature, the ZZ pin, has been implemented on the MCM63P733A. 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 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 interface can make use of the MCM63P733A. The burst counter feature of the BurstRAM can be disabled, and the SRAM can be configured to act upon a continuous stream of addresses. See Figure 4. CONTROL PIN TIE VALUES EXAMPLE (H VIH, L VIL)
