LH543620 Overview
The LH543620 is a FIFO (First-In, First-Out) memory device, based on fully-static CMOS RAM technology, capable of containing up to 1024 36-bit words. It can replace four or more nine-bit-wide FIFOs in many applications. The input port and the output port operate independently of each other.
LH543620 Key Features
- Fast Cycle Times: 20/25/30 ns
- Selectable 36/18/9-Bit Word Width for Both Input Port and Output Port
- Byte-Order-Reversal Function (i.e., ‘Big-Endian’ £ ‘Little-Endian’ Conversion)
- 16-mA-IOL Three-State Outputs
- Automatic Byte Parity Checking
- Selectable Byte Parity Generation
- Five Status Flags: Full, Almost-Full, Half-Full, Almost-Empty, and Empty
- All FIFO Status Flags are Synchronous (AE, HF, AF Through Programming of Control Register)
- Programmed Values may be entered from either Port
- Two Enable Control Signals for each Port
