Overview

CMOS PARALLEL-SERIAL FIFO 2048 x 9, 4096 x 9 Integrated Device Technology, Inc.
IDT72103 IDT72104 FEATURES: • 35ns parallel port access time, 45ns cycle time • 50MHz serial input/output frequency • Serial-to-parallel, parallel-to-serial, serial-to-serial, and parallel-to-parallel operations • Expandable in both depth and width with no external components • Flexishift™ — Sets programmable serial word width from 4 bits to any width with no external components • Multiple flags: Full, Almost-Full (Full-1/8),Full-MinusOne, Empty, Almost-Empty (Empty + 1/8), Empty-Plus One, and Half-Full • Asynchronous and simultaneous read or write operations • Dual-Port, zero fall-through time architecture • Retransmit capability in single-device mode • Packaged in 44-pin PLCC • Industrial temperature range (-40oC to +85oC) is available, tested to military electrical specifications APPLICATIONS: • • • • • • • • • High-speed data acquisition systems Local area network (LAN) buffer High-speed modem data buffer Remote telemetry data buffer FAX raster video data buffer Laser printer engine data buffer High-speed parallel bus-to-bus communications Magnetic media controllers Serial link buffer DESCRIPTION: The IDT72103/72104 are high-speed Parallel-Serial FlFOs to be used with high-performance systems for functions such as serial communications, laser printer engine control and local area networks.
A serial input, a serial output and two 9-bit parallel ports make four modes of data transfer possible: serial-to-parallel, parallel-to-serial, serial-to-serial, and parallel-to-parallel.
The IDT72103/72104 are expandable in both depth and width for all of these operational configurations.
