San Jose, Calif.IDT (Integrated Device Technology Inc.) has added a pair of chips to its growing family of multi-port devicesthe 9-Mbit 70P3519 and 4-Mbit 70P3599 high-speed 256K/128K x 36 bit synchronous dual-port devices.
For applications ranging from industrial control to medical imaging and communications, the 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 less power than existing products, according to IDT.
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.
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).
Pricing: In 10,000-unit quantities, the 9-Mbit synchronous dual-port devices are priced at $83.95 each and 4-Mbit dual port devices are available at $64.57.
