Description and Introduction

SwitchStarTM ATM Cell Based 8 x 8 1.2Gbps non-blocking Integrated Switching Memory The IDT77V400S156DS is a high-performance, low-power, 3.3V CMOS synchronous FIFO memory device. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 262,144 x 18 (4.5 Mbit)
- **Operating Voltage:** 3.3V ±10%
- **Operating Temperature Range:** Commercial (0°C to +70°C) / Industrial (-40°C to +85°C)
- **Speed Grade:** 156 MHz (6.4 ns access time)
- **Package:** 100-pin TQFP (Thin Quad Flat Pack)
- **I/O Type:** 3.3V LVTTL-compatible

### **Descriptions:**
- **Type:** Synchronous FIFO (First-In, First-Out) memory
- **Purpose:** Designed for high-speed buffering in networking, telecommunications, and data processing applications.
- **Architecture:** Supports independent read and write clocks for asynchronous operation.
- **Data Width:** 18-bit input and output (supports parity or control bits).

### **Features:**
1. **High-Speed Operation:** 
   - 156 MHz clock frequency (6.4 ns cycle time).
   - Zero wait-state operation at full speed.
  
2. **Low Power Consumption:** 
   - CMOS technology for reduced power usage.
   - Standby and sleep modes available.

3. **Flexible Depth Expansion:** 
   - Cascadable for deeper FIFOs using external logic.

4. **Programmable Flags:** 
   - Almost Full/Almost Empty, Half-Full, and programmable offset flags.
   - Supports configurable threshold levels.

5. **Retransmit Function:** 
   - Allows data to be reread without resetting the FIFO.

6. **Bypass Mode:** 
   - Enables direct data transfer from input to output for testing.

7. **Error Detection:** 
   - Optional parity checking on data inputs and outputs.

8. **Industrial-Grade Options:** 
   - Available in extended temperature range (-40°C to +85°C).

9. **Packaging:** 
   - 100-pin TQFP for compact PCB integration.

This device is optimized for applications requiring high-speed data buffering with minimal latency and power consumption.
