CMOS SERIAL-TO-PARALLEL FIFO 2048 x 9 4096 x 9 Integrated Device Technology, Inc. IDT72132 IDT72142 Features : - 35ns parallel-port access time, 45ns cycle time - 50MHz serial port shift rate - Expandable in depth and width with no external ponents - Programmable word lengths including 8, 9, 16-18, and 32-36 bit using Flexshift™ serial input without using any additional ponents - Multiple status flags: Full, Almost-Full (1/8 from full), Half-Full, Almost Empty (1/8 from empty), and Empty - Asynchronous and simultaneous read and write operations - Dual-Port zero fall-through architecture - Retransmit capability in single device mode - Produced with high-performance, low-power CMOS technology - Available in the 28-pin plastic DIP - Industrial temperature range (-40o C to +85o C) is available, tested to military electrical specifications DESCRIPTION: The IDT72132/72142 are high-speed, low-power serial-toparallel FIFOs. These FIFOs are ideally suited to serial munications applications, tape/disk controllers, and local area networks (LANs). The IDT72132/72142 can be configured with the IDTs parallel-to-serial FIFOs (IDT72131/72141) for bidirectional serial data buffering. The FIFO has a serial input port and a 9-bit parallel output port. Wider and deeper serial-to-parallel data buffers can be built using multiple IDT72132/72142 chips. IDTs unique Flexshift serial expansion logic (SIX, ) makes width expansion possible with no additional ponents. These FIFOs will expand to a variety of word widths including 8, 9, 16, and 32 bits. The IDT72132/142 can also be directly connected for depth expansion. Five flags are provided to monitor the FIFO. The full and empty flags prevent any FIFO data overflow or underflow conditions. The Almost-Full (7/8), Half-Full, and Almost Empty (1/8) flags signal memory utilization within the FIFO. The IDT72132/72142 is fabricated using IDTs high-speed submicron CMOS technology.
