IDT72V2113 Integrated Device Technology, IDT72V2113 Datasheet - Page 2

• Manufacturer Part Number: IDT72V2113
• Description: 256k X 18 / 512k X 9 Supersync Ii Fifo, 3.3v
• Manufacturer: Integrated Device Technology

DESCRIPTION:
First-In-First-Out (FIFO) memories with clocked read and write controls and a
flexible Bus-Matching x9/x18 data flow. These FIFOs offer numerous improve-
ments over previous SuperSync FIFOs, including the following:
• Flexible x9/x18 Bus-Matching on both read and write ports.
• The limitation of the frequency of one clock input with respect to the other has

been removed. The Frequency Select pin (FS) has been removed, thus it
is no longer necessary to select which of the two clock inputs, RCLK or WCLK,
is running at the higher frequency.
The IDT72V2103/72V2113 are exceptionally deep, high speed, CMOS
