IDT723613

CMOS Clocked FIFO With Bus Matching and Byte Swapping 64 x 36 Integrated Device Technology, Inc. IDT723613 FEATURES: Free-running CLKA and CLKB may be asynchronous or coincident (permits simultaneous reading and writing of data on a single clock edge) 64 x 36 storage capacity FIFO buffering data from Port A to Port B Mailbox bypass registers in each direction Dynamic Port B bus sizing of 36-bits (long word), 18-bits (word), and 9-bits (byte) Selection of Big- or Little-Endian format for word and byte bus sizes Three modes of byte-order swapping on Port B Programmable Almost-Full and Almost-Empty flags Microprocessor interface control logic FF, AF flags synchronized by CLKA EF, AE flags synchronized by CLKB Passive parity checking on each Port Parity Generation can be selected for each Port Low-power advanced BiCMOS technology Supports clock frequencies up to 67 MHz Fast access times of 10 ns Available in 132-pin quad flatpack (PQF) or space-saving 120-pin thin quad flatpack (TQFP) Industrial temperature range (-40oC to +85oC) is available, tested to military electrical specifications DESCRIPTION: The IDT723613 is a monolithic, high-speed, low-power, BiCMOS synchronous (clocked) FIFO memory which supports clock frequencies up to 67 MHz and has read-access times as fast as 10 ns. The 64 x 36 dual-port SRAM FIFO buffers data from port A to port B. The FIFO has flags to indicate empty and full conditions, and two programmable flags, Almost-F...
