The 71T75902 2.5V CMOS Synchronous SRAM organized as 1M x 18 (18 Megabit). It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Thus it has been given the name ZBTTM, or Zero Bus Turnaround.

The 71V016 3.3V CMOS SRAM is organized as 64K x 16. All bidirectional inputs and outputs of the 71V016 are LVTTL-compatible and operation is from a single 3.3V supply. Fully static asynchronous circuitry is used, requiring no clocks or refresh for operation.

The 71V124 3.3V CMOS SRAM is organized as 128K x 8. The JEDEC center power/GND pinout reduces noise generation and improves system performance. All bidirectional inputs and outputs of the 71V124 are LVTTL-compatible and operation is from a single 3.3V supply. Fully static asynchronous circuitry is used; no clocks or refreshes are required for operation.

The 71V2546 3.3V CMOS Synchronous SRAM is organized as 128K x 36. It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Thus, it has been given the name ZBTTM, or Zero Bus Turnaround. The 71V2546 has an on-chip burst counter. In the burst mode, it can provide four cycles of data for a single address presented to the SRAM.

The 71V2556 3.3V CMOS synchronous SRAM, organized as 128K x 36, is designed to eliminate dead bus cycles when turning the bus around between reads and writes or writes and reads. Thus, it has been given the name ZBT™, or Zero Bus Turnaround. The 71V2556 contains data I/O, address, and control signal registers. It can provide four cycles of data for a single address presented to the SRAM.

The 71V256SA 3.3V CMOS Asynchronous SRAM is organized as 32K x 8. When in standby mode, its very low power characteristics contribute to extended battery life. Under full standby mode (CS at CMOS level, f=0), power consumption is guaranteed to be less than 6.6mW. Fully static asynchronous circuitry is used; no clocks or refreshes are required for operation.

The 71V25761 3.3V CMOS synchronous SRAM is organized as 128K x 36 and contains write, data, address, and control registers. The burst mode feature offers the highest level of performance to the system designer, as the 71V25761 can provide four cycles of data for a single address presented to the SRAM.

The 71V30 high-speed 1K x 8 dual-port static RAM is designed to be used as a stand-alone 8-bit dual-port SRAM. It has two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power-down feature, controlled by CE, permits the on-chip circuitry of each port to enter a very low standby power mode.

The 71V321 is a high-speed 2K x 8 dual-port static RAM with internal interrupt logic for interprocessor communications. The device provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power-down feature, controlled by CE, permits the on-chip circuitry of each port to enter a very low standby power mode.

The 71V3556 3.3V CMOS synchronous SRAM, organized as 128K x 36, is designed to eliminate dead bus cycles when turning the bus around between reads and writes or writes and reads. Thus, it has been given the name ZBT™, or Zero Bus Turnaround. The 71V3556 contains data I/O, address, and control signal registers.
