Description and Introduction

1M x 16Bit x 4 Banks (64-MBIT) SDRAM The IC42S16400 is a SDRAM (Synchronous Dynamic Random Access Memory) module manufactured by ICSI (Integrated Circuit Solution Inc.). Below are the factual specifications, descriptions, and features of the IC42S16400:

### **Specifications:**
- **Type:** Synchronous DRAM (SDRAM)  
- **Density:** 64Mbit (4M x 16-bit)  
- **Organization:** 4 banks, 1M words x 16 bits  
- **Voltage Supply:** 3.3V (±0.3V)  
- **Clock Frequency:** Up to 143 MHz  
- **Access Time:** 5.4 ns (CL=3)  
- **Refresh Method:** Auto-refresh (8K cycles/64ms) and self-refresh  
- **CAS Latency (CL):** 2 or 3 programmable  
- **Burst Length:** 1, 2, 4, 8, or full page  
- **Operating Temperature:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package:** 54-pin TSOP-II (400 mil width)  

### **Descriptions:**
- The IC42S16400 is a high-speed CMOS SDRAM designed for applications requiring high bandwidth and low power consumption.  
- It supports burst read/write operations for efficient data transfer.  
- The device is fully compatible with JEDEC standards for SDRAM.  

### **Features:**
- **Synchronous Operation:** Clock-controlled commands and data transfer.  
- **Programmable Burst Length:** Supports 1, 2, 4, 8, or full-page bursts.  
- **Auto Precharge:** Option for automatic precharge after burst operations.  
- **Power Saving Modes:** Self-refresh and power-down modes for reduced power consumption.  
- **Single 3.3V Power Supply:** Low-voltage operation.  
- **Industrial-Grade Option:** Available for extended temperature range applications.  

This information is based on the manufacturer's datasheet for the IC42S16400 SDRAM module.

Application Scenarios & Design Considerations

1M x 16Bit x 4 Banks (64-MBIT) SDRAM

Alternative Part Number

  • IS42S16400J --: Pin-compatible 64Mb SDR SDRAM from ISSI with the same 4M x 16 organization and 3.3V interface, widely available and a common drop-in replacement.
  • MT48LC4M16A2 --: Industry-standard 64Mb SDR SDRAM organized as 4M x 16 with compatible timing and pinout, well documented and broadly stocked.
  • W9864G6JH --: 64Mb SDR SDRAM in 4M x 16 configuration with similar 3.3V LVTTL interface and timing, suitable as a functional substitute.
  • IS42S16400J-7TLI --: Same 64Mb SDR SDRAM density and organization from ISSI's IS42S series, pin-compatible with the IC42S family and widely available.
  • MT48LC4M16A2P-7E --: Micron 64Mb SDR SDRAM in 4M x 16 organization, functionally equivalent to the IC42S16400 with similar timing and package options.
  • W9864G6JH-6 --: Winbond 64Mb SDR SDRAM organized as 4M x 16, a common drop-in alternative for the IC42S16400 in many designs.
