1998.6.18 Ver.A MITSUBISHI LSIs PRELIMINARY Notice: This is not a final specification. Some parametric limits are subject to change. M5M564R16DJ,TP-10,-12,-15 1048576-BIT (65536-WORD BY 16-BIT) CMOS STATIC RAM DESCRIPTION The M5M564R16D is a family of 65536-word by 16-bit static RAMs, fabricated with the high performance CMOS process and designed for high speed application. These devices operate on a single 3.3V supply, and are directly TTL compatible. They include a power down feature as well. In write and read cycles, the lower and upper bytes are able to be controled either togethe or separately by LB and UB.

Each mode is summarized in the function table. A write cycle is executed whenever the low level W overlaps with low level LB and/or low level UB and low level S. The address must be set-up before write cycle and must be stable during the entire cycle. The data is latched into a cell on the traling edge of W, LB, UB or S, whichever occurs first, requiring the set-up and hold time relative to these edge to be maintained. The output enable input OE directly controls the output stage. Setting the OE at a high level, the output stage is in a high impedance state, and the data bus contention problem in the write cycle is eliminated. A read cycle is excuted by setting W at a high level and OE at a low level while LB and/or UB and S are in an active state. (LB and/or UB=L, S=L) When setting LB at a high level and other pins are in an active state, upper-Byte are in a selectable mode in which both reading and writing are enable, and lower-Byte are in a non-selectable mode. And when setting UB at a high level .
