IDT707288S

The IDT707288S is a high-speed 64K x 16 (1M bit) Bank-Switchable Dual-Ported SRAM organized into four independent 16K x 16 banks. The device has two independent ports with separate controls, addresses, and I/O pins for each port, allowing each port to asynchronously access any 16K x 16 memory block not already accessed by the other port. Accesses by the ports into specific banks are controlled via bank select pin inputs under the user's control. Mailboxes of the IDT707288S are provided to allow inter-processor communications. Interrupts are provided to indicate mailbox writes have occurred. An automatic power down feature controlled by the chip enables (CE₀ and CE₁) permits the on-chip circuitry of each port to enter a very low standby power mode and allows fast depth expansion.

The IDT707288S offers a maximum address-to-data access time as fast as 20ns, while typically operating on only 900mW of power, and is available in a 100-pin Thin Quad Plastic Flatpack (TQFP) and a 108-pin ceramic Pin Grid Array (PGA).
