256K x 36, 512K x 18 3.3V Synchronous ZBT™ SRAMs ZBT™ Feature 3.3V I/O, Burst Counter Pipelined Outputs Features ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ IDT71V65603 IDT71V65803 Address and control signals are applied to the SRAM during one clock cycle, and two cycles later the associated data cycle occurs, be it read or write. The IDT71V65603/5803 contain data I/O, address and control signal registers. Output enable is the only asynchronous signal and can be used to disable the outputs at any given time. A Clock Enable (CEN) pin allows operation of the IDT71V65603/5803 to be suspended as long as necessary. All synchronous inputs are ignored when (CEN) is high and the internal device registers will hold their previous values. There are three chip enable pins (CE1, CE2, CE2) that allow the user to deselect the device when desired. If any one of these three are not asserted when ADV/LD is low, no new memory operation can be initiated. However, any pending data transfers (reads or writes) will be completed. The data bus will tri-state two cycles after chip is deselected or a write is initiated. The IDT71V65603/5803 have an on-chip burst counter. In the burst mode, the IDT71V65603/5803 can provide four cycles of data for a single address presented to the SRAM. The order of the burst sequence is defined by the LBO input pin. The LBO pin selects between linear and interleaved burst sequence. The ADV/LD signal is used to load a new external address (ADV/LD = LOW) or increment the internal burst counter (ADV/LD = HIGH). The IDT71V65603/5803 SRAM utilize IDT's latest high-performance CMOS process, and are packaged in a JEDEC Standard 14mm x 20mm 100pin thin plastic quad flatpack (TQFP) as well as a 119 ball grid array (BGA) and 165 fine pitch ball grid array (fBGA) . 256K x 36, 512K x 18 memory configurations Supports high performance system speed - 150MHz (3.8ns Clock-to-Data Access) ZBTTM Feature - No dead cycles between write and read cycles Internally synchronized output buffer enable eliminates the need to control OE Single R/W (READ/WRITE) control pin Positive clock-edge triggered address, data, and control signal registers for fully pipelined applications 4-word burst capability (interleaved or linear) Individual byte write (BW1 - BW4) control (May tie active) Three chip enables for simple depth expansion 3.3V power supply (±5%) 3.3V I/O Supply (VDDQ) Power down controlled by ZZ input Packaged in a JEDEC standard 100-pin plastic thin quad flatpack (TQFP), 119 ball grid array (BGA) and 165 fine pitch ball grid array(fBGA). Description The IDT71V65603/5803 are 3.3V high-speed 9,437,184-bit (9 Megabit) synchronous SRAMS. They are designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Thus, they have been given the name ZBTTM, or Zero Bus Turnaround.

DSC-5304/05 IDT71V65603, IDT71V65803, 256K x 36, 512K x 18, 3.3V Synchronous SRAMs with Feature, 3.3V I/O, Burst Counter, and Pipelined Outputs ZBT Commercial and Industrial Temperature Ranges Pin Definitions(1) Symbol Pin Function I/O Active Description A0-A18 Address Inputs I N/A Synchronous Address inputs. The address register is triggered by a combination of the rising edge of CLK, ADV/LD low, CEN low, and true chip enables. ADV/LD Advance / Load I N/A ADV/LD is a synchronous input that is used to load the internal registers with new address and control when it is sampled low at the rising edge of clock with the chip selected. When ADV/LD is low with the chip deselected, any burst in progress is terminated. When ADV/ LD is sampled high then the internal burst counter is advanced for any burst that was in progress. The external addresses are ignored when ADV/LD is sampled high. R/W Read / Write I N/A R/W signal is a synchronous input that identifies whether the current load cycle initiated is a Read or Write access to the memory array. The data bus activity for the current cycle takes place two clock cycles later. CEN Clock Enable I LOW Synchronous Clock Enable Input. When CEN is sampled high, all other synchronous inputs, including clock are ignored and outputs re main unchanged. The effect of CEN sampled high on the device outputs is as if the low to high clock transition did not occur. For normal operation, CEN must be sampled low at rising edge of clock. BW1-BW4 Individual Byte Write Enables I LOW Synchronous byte write enables. Each 9-bit byte has its own active low byte write enable. On load write cycles (When R/W and ADV/LD are sampled low) the appropriate byte write signal (BW1-BW4) must be valid. The byte write signal must also be valid on each cycle of a burst write. Byte Write signals are ignored when R/W is sampled high. The appropriate byte(s) of data are written into the device two cycles later. BW1-BW4 can all be tied low if always doing write to the entire 36-bit word. CE1, CE2 Chip Enables I LOW Synchronous active low chip enable. CE1 and CE2 are used with CE2 to enable the IDT71V65603/5803. (CE1 or CE2 sampled high or CE2 sampled low) and ADV/LD low at the rising edge of clock, initiates a deselect cycle. The ZBTTM has a two cycle deselect, i.e., the data bus will tri-state two clock cycles after deselect is initiated. CE2 Chip Enable I HIGH Synchronous active high chip enable. CE2 is used with CE1 and CE2 to enable the chip. CE2 has inverted polarity but otherwise identical to CE1 and CE2. CLK Clock I N/A This is the clock input to the IDT71V65603/5803. Except for OE, all timing references for the device are made with respect to the rising edge of CLK. I/O0-I/O31 I/OP1-I/OP4 Data Input/Output I/O N/A 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. LBO Linear Burst Order I LOW 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 it must not change during device operation. OE Output Enable I LOW Asynchronous output enable. OE must be low to read data from the 71V65603/5803. When OE is high the I/O pins are in a high-impedance state. OE does not need to be actively controlled for read and write cycles. In normal operation, OE can be tied low. ZZ Sleep Mode I N/A Asynchronous sleep mode input. ZZ HIGH will gate the CLK internally and power down the 71V65603/5803 to its lowest power consumption level. Data retention is guaranteed in Sleep Mode. VDD Power Supply N/A N/A 3.3V core power supply. VDDQ Power Supply N/A N/A 3.3V I/O Supply. VSS Ground N/A N/A Ground. 5304tbl 02 NOTE: 1.

To avoid bus contention, the output buffers are designed such that tCHZ (device turn-off) is about 1ns faster than tCLZ (device turn-on) at a given temperature and voltage. The specs as shown do not imply bus contention because tCLZ is a Min. parameter that is worse case at totally different test conditions (0 deg.
