Synchronous dual-port RAM
3 September 2008
DSP, Micros & Memory
IDT recently announced the availability of two new dual-port variants to its family of multiport memory devices.
For applications ranging from industrial control to medical imaging and communications, the new 9 Mbit and 4 Mbit dual-port devices deliver 200 MHz performance to satisfy demanding memory buffering requirements.
Dual-port devices integrate memory and control logic to enable simultaneous access to a common central memory, through independent ports. By offering a 1,8 V core voltage, the devices offer a low-power solution.
The new 9 Mbit 70P3519 and 4 Mbit 70P3599 are high-speed 256 K/128 K x 36 bit synchronous dual-port devices, providing a comprehensive range of synchronous functionality. In addition, the devices also enable management of 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, while registers on control, data and address inputs feature minimal setup-and-hold times. By including input data registers, the devices are optimised for applications having unidirectional or bidirectional data flow in bursts. An automatic power-down feature, controlled by chip enable pins, permits the on-chip circuitry of each port to enter a very low standby power mode.
Both devices support I/O voltages of 3,3, 2,5 or 1,8 V on one or both ports, from a core supply of 1,8 V. To ease adoption, both devices are available in the same packages as existing IDT dual-port solutions: 266 pin BGA (ball grid array), 208 pin PQFP (plastic quad FlatPack), and 208 fpBGA (fine pitch BGA).
