3、FP), 119 ball grid array (BGA) and 165 fine pitch ball grid arrayPin Description SummaryDescriptionThe IDT71V3577/79 are high-speed SRAMs organized as 128K x 36/256K x 18. The IDT71V3577/79 SRAMs contain write, data,address and control registers. There are no registers in the data output path (flow-
4、through architecture). Internal logic allows the SRAM to gen-erate a self-timed write based upon a decision which can be left until the end of the write cycle.The burst mode feature offers the highest level of performance to the system designer, as the IDT71V3577/79 can provide four cycles of data f
5、or a single address presented to the SRAM. An internal burst address counter accepts the first cycle address from the processor, initiating the access sequence. The first cycle of output data will flow-through from the array after a clock-to-data access time delay from the rising clock edge of the s
6、ame cycle. If burst mode operation is selected (ADV =LOW), the subsequent three cycles of output data will be available to the user on the next three rising clock edges. The order of these three addresses are defined by the internal burst counter and the LBO input pin.The IDT71V3577/79 SRAMs utilize
7、 IDTs latest high-performance CMOS process and are packaged in a JEDEC standard 14mm x 20mm 100-pin thin plastic quad flatpack (TQFP) as well as a 119 ball grid array (BGA) and a 165 fine pitch ball grid array (fBGA).A 0-A 17Address Inputs Input Synchronous CE Chip Enable Input Synchronous CS 0, CS

12、K and ADSC Low or ADSP Low and CE Low.ADSC Address Status (Cache Controller)I LOW Synchronous Address Status from Cache Controller. ADSC is an active LOW input that is used to load the address registers with new addresses.ADSP Address Status (Processor)I LOW Synchronous Address Status from Processor
13、. ADSP is an active LOW input that is used to load the address registers with new addresses. ADSP is gated by CE .ADVBurst Address Advance ILOWSynchronous Address Advance. ADV is an active LOW input that is used to advance the internal burst counter,controlling burst access after the initial address
14、 is loaded. When the input is HIGH the burst counter is not incremented; that is, there is no address advance.BWE Byte Write EnableI LOWSynchronous byte write enable gates the byte write inputs BW 1-BW 4. If BWE is LOW at the rising edge of CLK then BW x inputs are passed to the next stage in the ci
15、rcuit. If BWE is HIGH then the byte write inputs are blocked and only GW can initiate a write cycle.BW 1-BW 4Individual Byte Write Enables I LOW Synchronous byte write enables. BW 1 controls I/O 0-7, I/O P1, BW 2 controls I/O 8-15, I/O P2, etc. Any active byte write causes all outputs to be disabled
