Mitsubishi announces 4-MBIT, 12-NS fast SRAMs that are among the CMOS speed leaders; Revolutionary pin-out design reduces noise, supports high throughput and preserves data integrity for high-speed networking and telecom applications.SUNNYVALE, Calif.--(BUSINESS WIRE)--May 20, 1997--The Electronic Device Group of Mitsubishi Electronics America, Inc., today announced the availability of 4-Mbit SRAMs that have access times as fast as 12 ns, making Mitsubishi among the speed leaders in SRAMs using a CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. process technology. They also feature a revolutionary dual center Vcc and Ground pin-out design, which significantly reduces noise susceptibility, allowing them to support high throughput and preserve data integrity in high-speed telecommunications and networking applications. The density and speed of the 4-Mbit SRAMs are particularly advantageous for designers of communications, networking and storage applications, as well as the following applications: -0- -- high-density cache modules for midrange to high-end mainframes and servers -- PostScript(r) graphics acceleration for high-end printers -- wireless communication base stations -0- "These 4-Mbit CMOS devices are for significantly higher density applications than Mitsubishi's first revolutionary pin-out Fast SRAMs introduced last October," said Reid Swanson, Mitsubishi Electronics' marketing manager for Fast SRAM See static RAM. SRAM - static random-access memory products. "The revolutionary pin-out design significantly reduces switching noise, allowing these Fast SRAMs to have higher performance in telecom and networking applications. Since they are available in both 3.3-volt and 5-volt single-supply voltages, these devices provide developers with a migration path to lower power applications." Designed in Mitsubishi's 0.4-mm, high-performance CMOS process technology, the 4-Mbit Fast SRAMs are available in 4-Mword x 1-bit, 1-Mword x 4-bit, and 500-Kword x 8-bit organizations and 3.3-volt single-supply or 5-volt single-supply versions, featuring maximum access times of 12ns, 15ns and 20ns. The Fast SRAMs include a power-down feature that substantially reduces power consumption while providing the same fast access time as normal power mode. All inputs and outputs are also TTL (1) (Time To Live) A parameter in a network packet that sets a time limit to its validity. In order to prevent an IP packet from propagating endlessly through the network, the value in the TTL field is reduced by each router. compatible. The 3.3-volt single-supply 4-Mbit Fast SRAMs are being offered in x1, x4, and x8 organizations under the M5M5V4R01, M5M5V4R04, M5M5V4R08 product numbers, respectively. The 5-volt single-supply 4-Mbit Fast SRAMs are being offered in x1, x4, and x8 organizations under the M5M54R01, M5M54R04, M5M54R08 product numbers, respectively. The 3.3-volt M5M5V4R01, M5M5V4R04, and M5M5V4R08 devices feature a typical active power dissipation of 297mW, 297mW, and 363mW, respectively, with each device dissipating 3.3mW in standby mode A sleep mode in a portable computer that provides an almost immediate resumption of operation when turned back on. In standby mode, the hard disk and display are turned off, and the CPU is throttled down to its lowest-power state. . The 5-volt, M5M54R01, M5M54R04, and M5M54R08 devices feature a typical active power dissipation of 450mW, 450mW, and 550mW, respectively, with each device dissipating 5mW in standby mode. Other key features: -0- -- "Chip-select" input and tristate outputs make memory expansion easy for developers, allowing them to make OR-ties with other chips. -- "Output enable" input eliminates data bus contention Bus contention is an undesirable state of the bus of a computer, in which more than one memory mapped device or the CPU is attempting to place output values onto the bus at once. problems during the write cycle. -- No clocks and no refresh for fully static operation. -- Common data I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output on the M5M5V4R01, M5M5V4R04, M5M54R01, M5M54R04 devices. Product packaging, availability and pricing The M5M5V4R01, M5M54R01, M5M5V4R04, and M5M54R04 Fast SRAMs are available in 32-pin small outline J-lead See SOJ. (SOJ (Small Outline package J-lead) A small-dimension, plastic, rectangular surface mount chip package with j-shaped pins on its two long sides. See J-lead, SOP and chip package. SOJ - Small Outline J ) packages. The M5M5V4R08 and M5M54R08 Fast SRAMs are available in 36-pin SOJ packages. The Fast SRAMs are sampling now and will be shipping in volume during the third quarter of 1997. Pricing is $42 each in 1,000-unit quantities.
