Quick Detail:
CMOS ASYNCHRONOUS FIFO 65,536 x 9
Description:
The IDT7208 is a monolithic dual-port memory buffer with internal pointers that load and empty data on a first-in/first-out basis. The device uses Full and Empty flags to prevent data overflow and underflow and expansion logic to allow for unlimited expansion capability in both word size and depth.
Data is toggled in and out of the device through the use of the Write (W) and Read (R) pins.
The device's 9-bit width provides a bit for a control or parity at the user’s option. It also features a Retransmit (RT) capability that allows the read pointer to be reset to its initial position when RT is pulsed LOW. A Half-Full Flag is available in the single device and width expansion modes.
The IDT7208 is fabricated using IDT’s high-speed CMOS technology. It is designed for applications requiring asynchronous and simultaneous read/writes in multiprocessing, rate buffering, and other applications.
Applications:
• 65536 x 9 storage capacity
• High-speed: 15ns access time
• Low power consumption
— Active: 660mW (max.)
— Power-down: 44mW (max.)
• Asynchronous and simultaneous read and write
• Fully expandable in both word depth and width
• Pin and functionally compatible with IDT720x family
• Status Flags: Empty, Half-Full, Full
• Retransmit capability
• High-performance CMOS technology
• Industrial temperature range (-40oC to +85oC) is available, tested to military electrical specifications
