LH543611规格书详情
FUNCTIONAL DESCRIPTION
The LH543611 and LH543621 contain two FIFO buffers, FIFO #1 and FIFO #2. These operate in parallel, but in opposite directions, for bidirectional data buffering. FIFO #1 and FIFO #2 each are organized as 512 or 1024 by 36 bits. The LH543611 and LH543621 are ideal either for wide unidirectional applications or for bidirectional data applications; component count and board area are reduced.
FEATURES
• Pin-Compatible and Functionally Upwards-Compatible with Sharp LH5420 and LH543601, but Deeper
• Expanded Control Register that is Fully Readable as well as Writeable
• Fast Cycle Times: 18/20/25/30/35 ns
• Improved Input Setup and Flag Out Timing
• Two 512 × 36-bit FIFO Buffers (LH543611) or Two 1024 × 36-bit FIFO Buffers (LH543621)
• Full 36-bit Word Width
• Selectable 36/18/9-bit Word Width on Port B; Selection May be Changed Without Resetting the BiFIFO
• Programmable Byte-Order Reversal – ‘Big-Endian ↔ Little-Endian Conversion’
• Independently-Synchronized (‘Fully-Asynchronous’) Operation of Port A and Port B
• ‘Synchronous’ Enable-Plus-Clock Control at Both Ports
• R/W, Enable, Request, and Address Control Inputs are Sampled on the Rising Clock Edge
• Synchronous Request/Acknowledge ‘Handshake’ Capability; Use is Optional
• Device Comes Up Into a Known Default State at Reset; Programming is Allowed, but is not Required
• Asynchronous Output Enables
• Five Status Flags per Port: Full, Almost-Full, Half-Full, Almost-Empty, and Empty
• All Flags are Independently Programmable for Either Synchronous or Asynchronous Operation
• Almost-Full Flag and Almost-Empty Flag Have Programmable Offsets
• Mailbox Registers with Synchronized Flags
• Data-Bypass Function
• Data-Retransmit Function
• Automatic Byte Parity Checking with Programmable Parity Flag Latch
• Programmable Byte Parity Generation
• Programmable Byte, Half-Word, or Full-Word Oriented Parity Operations
• 8 mA-IOL High-Drive Three-State Outputs with Built-In Series Resistor
• TTL/CMOS-Compatible I/O
• Space-Saving PQFP and TQFP Packages
