CMOS ASYNCHRONOUS FIFO IDT7200L 256 x 9, 512 x 9 and 1,024 x 9 IDT7201LA IDT7202LA o o Industrial temperature range (40 C to +85 C) is available FEATURES: (plastic packages only) First-In/First-Out dual-port memory Green parts available, see ordering information 256 x 9 organization (IDT7200) 512 x 9 organization (IDT7201) DESCRIPTION: 1,024 x 9 organization (IDT7202) The IDT7200/7201/7202 are dual-port memories that load and empty data Low power consumption on a first-in/first-out basis. The devices use Full and Empty flags to prevent data Active: 440mW (max.) overflow and underflow and expansion logic to allow for unlimited expansion Power-down: 28mW (max.) capability in both word size and depth. Ultra high speed12ns access time The reads and writes are internally sequential through the use of ring Asynchronous and simultaneous read and write pointers, with no address information required to load and unload data. Data Fully expandable by both word depth and/or bit width is toggled in and out of the devices through the use of the Write (W) and Read 720x family is pin and functionally compatible from 256 x 9 to 64k x 9 (R) pins. Status Flags: Empty, Half-Full, Full The devices utilize a 9-bit wide data array to allow for control and parity bits Auto-retransmit capability at the users option. This feature is especially useful in data communications High-performance CEMOS technology applications where it is necessary to use a parity bit for transmission/reception Military product compliant to MIL-STD-883, Class B error checking. It also features a Retransmit (RT) capability that allows for reset Standard Military Drawing 5962-87531, 5962-89666, 5962-89863 of the read pointer to its initial position when RT is pulsed LOW to allow for and 5962-89536 are listed on this function retransmission from the beginning of data. A Half-Full Flag is available in the Dual versions available in the TSSOP package.

They IDT7280 = 2 x IDT7200 are designed for those applications requiring asynchronous and simultaneous IDT7281 = 2 x IDT7201 read/writes in multiprocessing and rate buffer applications. Military grade IDT7282 = 2 x IDT7202 product is manufactured in compliance with MIL-STD-883, Class B.
