Expanding Multi-port Solutions Allow Higher Performance Memory Buffering
7月 14, 2008
SAN JOSE, Calif., July 14, 2008 – IDT® (Integrated Device Technology, Inc.; NASDAQ: IDTI), a leading provider of essential mixed signal semiconductor solutions that enrich the digital media experience, today announced it has added two new dual-port devices to its growing family of multi-port devices. For applications ranging from industrial control to medical imaging and communications, the new 9-Mbit and 4-Mbit dual-port devices deliver 200MHz performance to satisfy demanding memory buffering requirements. By offering a 1.8V core voltage, the devices utilize significantly less power than existing solutions.
Dual-port devices integrate memory and control logic to enable simultaneous access to a common central memory through independent ports. The IDT solutions allow customers to increase bandwidth and reduce design complexity by solving inter-chip connection issues while offering improved time-to-market by using proven off-the-shelf devices
“At IDT, we continue to look at ways to improve our existing products to provide our customers evolutionary upgrades to solve their next-generation concerns before these concerns become problems,” said Carl May, marketing director for the IDT Flow Control Management group. “These new devices offer significant improvements in performance and power for our customers.”
Features and Benefits
The new 9-Mbit IDT 70P3519 and 4-Mbit 70P3599 are high-speed 256K/128K x 36 bit synchronous dual-port devices. The devices provide a comprehensive range of synchronous functionality, allowing IDT customers to optimize their designs for greater performance and lower power. In addition, the devices also enable customers to manage simultaneous access to a single memory address without the need for external devices. Synchronous functions include counters, multiple independent chip and byte enables, and synchronous interrupts. Moreover, registers on control, data, and address inputs provide minimal setup and hold times allowing faster time-to-market. By including input data registers, the dual-port devices are optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power-down feature, controlled by CE0 and CE1 chip enable pins, permits the on-chip circuitry of each port to enter a very low standby power mode.
The 70P3519 and 70P3599 can support I/O voltages of 3.3V, 2.5V or 1.8V on one or both ports. The power supply for the core of the devices (VDD) is 1.8V. For additional information on the devices, visit www.idt.com/go/synch-dp.
Pricing and Availability
To ease adoption for IDT customers, both the IDT 70P3519 and the 70P3599 are available in the same packages as existing IDT dual-port solutions: 256-pin Ball Grid Array (BGA), 208-pin Plastic Quad Flatpack (PQFP), and 208-pin fine pitch Ball Grid Array (fpBGA). The 9-Mbit synchronous dual-port devices are priced at $83.95 each in 10,000-unit quantities and are sampling now. The 4-Mbit dual port devices are available at $64.57 each in 10,000 unit quantities and are sampling now.
