The IDT71V67603/7803 SRAMs contain write, data, address and control registers. Internal logic allows the SRAM to generate 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 IDT71V67603/7803 can provide four cycles of data for 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 be pipelined for one cycle before it is available on the next rising clock edge. 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 IDT71V67603/7803 SRAMs utilize IDT’s latest high-performance CMOS process and are packaged in a JEDEC standard 14mm x 20mm 100pin thin plastic quad flatpack (TQFP), a 119 ball grid array (BGA) and a 165 fine pitch ball grid array (fBGA).

The address register is trig gered by a combination of the rising edge of CLK and ADSC Low or ADSP Low and CE Low. Synchronous Address Status from Cache Controller. ADSC is an active LOW input that is used to load the address registers with new addresses. Synchronous Address Status from Processor. ADSP is an active LOW input that is used to load the address registers with new addresses. ADSP is gated by CE. Synchronous Address Advance. ADV is an active LOW input that is used to advance the internal burst counter, controlling burst access after the initial address is loaded. When the input is HIGH the burst counter is not incremented; that is, there is no address advance. Synchronous byte write enable gates the byte write inputs BW1-BW4. If BWE is LOW at the rising edge of CLK then BWx inputs are passed to the next stage in the circuit. If BWE is HIGH then the byte write inputs are blocked and only GW c an initiate a write cycle. Synchronous byte write enables. BW1 c ontrols I/O0-7, I/OP1, BW2 c ontrols I/O8-15, I/OP2, etc. Any active byte write causes all outputs to be disabled. Synchronous chip enable. CE is used with CS 0 and CS1 to enable the IDT71V67603/7803. CE also gates ADSP. This is the clock input. All timing references for the device are made with respect to this input. Synchrono us active HIGH chip select. CS 0 is used with CE and CS1 to enable the chip. Synchronous active LOW chip select. CS1 is used with CE and CS0 to enable the chip. Synchronous global write enable. This input will write all four 9-bit data bytes when LOW on the rising edge of CLK. GW s upersedes individual byte write enables. Synchronous data input/output (I/O) pins. Both the data input path and data output path are registered and triggered by the rising edge of CLK. Asynchronous burst order selection input. When LBO is HIGH, the interleaved burst sequence is selected. When LBO is LOW the Linear burst sequence is selected. LBO is a static input and must not change state while the device is operating. Asynchronous output enable. When OE is LOW the data output drivers are enabled on the I/O pins if the chip is also selected. When OE is HIGH the I/O pins are in a highimpedance state. 3.3V core power supply. 3.3V I/O Supply. Ground. NC pins are not electrically connected to the device. Asynchronous sleep mode input. ZZ HIGH will gate the CLK internally and power down the IDT71V67603/7803 to its lowest power consumption level. Data retention is guaranteed in Sleep Mode. 5310 tbl 02 ADSC ADSP ADV BWE I LOW BW1-BW4 CE CLK CS 0 Individual Byte Write Enables Chip Enable Clock Chip Select 0 Chip Select 1 Global Write Enable Data Input/Output Linear Burst Order I I I I I I I/O I LOW LOW N/A HIGH LOW LOW N/A LOW CS1 GW I/O0-I/O31 I/OP1-I/OP4 LBO OE Output Enable I LOW VDD VDDQ VSS NC ZZ Power Supply Power Supply Ground No Connect Sleep Mode N/A N/A N/A N/A I N/A N/A N/A N/A HIGH NOTE: 1.
