1 / 12 page MCM69F536C 1 MOTOROLA FAST SRAM 32K x 36 Bit Flow–Through BurstRAM Synchronous Fast Static RAM The MCM69F536C is a 1M–bit synchronous fast static RAM designed to pro- vide a burstable, high performance, secondary cache for the 68K Family, PowerPC ™, 486, i960™, and Pentium™ microprocessors. It is organized as 32K words of 36 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 data RAM applications. Synchronous design allows precise cycle control with the use of an external clock (K). BiCMOS 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 MCM69F536C (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 four bytes are designated as “a”, “b”, “c”, and “d”. SBa controls DQa, SBb controls DQb, and so on. 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 MCM69F536C operates from a 3.3 V power supply and all inputs and outputs are LVTTL compatible. • MCM69F536C–8.5 = 8.5 ns Access / 12 ns Cycle MCM69F536C–9 = 9 ns Access / 12 ns Cycle MCM69F536C–10 = 10 ns Access / 15 ns Cycle MCM69F536C–12 = 12 ns Access / 16.6 ns Cycle • Single 3.3 V + 10%, – 5% Power 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 • 5 V Tolerant on all Pins (Inputs and I/Os) • 100–Pin TQFP Package The PowerPC name is a trademark of IBM Corp., used under license therefrom. i960 and Pentium are trademarks of Intel Corp.
