DSC-3208/5 FEATURES: ••••• The IDT7280 is equivalent to two IDT7200 256 x 9 FIFOs ••••• The IDT7281 is equivalent to two IDT7201 512 x 9 FIFOs ••••• The IDT7282 is equivalent to two IDT7202 1,024 x 9 FIFOs ••••• The IDT7283 is equivalent to two IDT7203 2,048 x 9 FIFOs ••••• The IDT7284 is equivalent to two IDT7204 4,096 x 9 FIFOs ••••• The IDT7285 is equivalent to two IDT7205 8,192 x 9 FIFOs ••••• Low power consumption — Active: 685 mW (max.) — Power-down: 83 mW (max.) ••••• Ultra high speed—12 ns access time ••••• Asynchronous and simultaneous read and write ••••• Offers optimal combination of data capacity, small foot print and functional flexibility ••••• Ideal for bi-directional, width expansion, depth expansion, bus-matching, and data sorting applications ••••• Status Flags: Empty, Half-Full, Full ••••• Auto-retransmit capability ••••• High-performance CMOS technology ••••• Space-saving TSSOP ••••• Industrial temperature range (–40 °°°°°C to +85°°°°°C) is available DESCRIPTION: The IDT7280/7281/7282/7283/7284/7285 are dual-FIFO memories that load and empty data on a first-in/first-out basis. These devices are functional andcompatibletotwoIDT7200/7201/7202/7203/7204/7205FIFOsinasingle package with all associated control, data, and flag lines assigned to separate pins. The devices use Full and Empty flags to prevent data overflow and underflowandexpansionlogictoallowforunlimitedexpansioncapabilityinboth word size and depth. Thereadsandwritesareinternallysequentialthroughtheuseofringpointers, with no address information required to load and unload data. Data is toggled in and out of the devices through the use of the Write ( W) and Read (R) pins. The devices utilize a 9-bit wide data array to allow for control and parity bits at the user’s option. This feature is especially useful in data communications applications where it is necessary to use a parity bit for transmission/reception errorchecking.ItalsofeaturesaRetransmit( RT)capabilitythatallowsforreset of the read pointer to its initial position when RT is pulsed LOW to allow for retransmission from the beginning of data. A Half-Full Flag is available in the single device mode and width expansion modes. These FIFOs are fabricated using IDT’s high-speed CMOS technology. They are designed for those applications requiring asynchronous and simul- taneous read/writes in multiprocessing and rate buffer applications.
