- Features programmable burst lengths and sequential/interleaved burst modes.  
- Auto refresh and self-refresh modes are available for power-saving operation.  

### **Features:**
- **Synchronous Operation:** Clock-controlled command and data operations.  
- **Programmable Burst Length:** Supports 1, 2, 4, 8, or full-page burst.  
- **CAS Latency Options:** 2 or 3 programmable.  
- **Auto Precharge:** Configurable for each burst access.  
- **Low Power Consumption:** Standby and power-down modes supported.  
- **Single 3.3V Power Supply:** No additional voltage requirements.  
- **Burst Termination:** Supports burst stop and precharge commands.  

This information is based solely on the manufacturer's datasheet for the IS42S32800D-7BLI.

Application Scenarios & Design Considerations

8M x 32 256Mb SYNCHRONOUS DRAM

Alternative Part Number

  • MT48LC32M8A2P-7E --: 32M x 8 SDR SDRAM in the same 54-pin TSOP package with 7ns speed grade, a direct functional equivalent to the IS42S32800D.
  • W9825G6KH-6 --: 256Mb SDR SDRAM organized as 32M x 8 with compatible interface and timing, widely used as a drop-in substitute for ISSI 32M x 8 parts.
  • AS4C32M8SA-7TCN --: 32M x 8 SDR SDRAM in 54-pin TSOP II with 7ns speed, specifically marketed as a pin-compatible replacement for IS42S32800 series devices.
