Description and Introduction

131,072-Word X 8-Bit High-Speed PSRAM **Introduction to the MSM548128BL-70GS-K Memory Module**  

The MSM548128BL-70GS-K is a high-performance synchronous dynamic random-access memory (SDRAM) module designed for applications requiring fast data access and reliable operation. Manufactured with advanced semiconductor technology, this component offers a 128Mb (16M × 8-bit) memory configuration, making it suitable for embedded systems, networking equipment, and industrial electronics.  

Operating at a speed grade of 70ns, the MSM548128BL-70GS-K ensures efficient data processing with low latency. Its synchronous interface allows for precise timing coordination with the system clock, enhancing overall performance in high-speed environments. The module operates at a standard 3.3V supply voltage, balancing power efficiency with robust signal integrity.  

Built with industry-standard packaging, this SDRAM module supports auto-refresh and self-refresh modes, reducing power consumption during idle periods. Its compatibility with various microcontrollers and processors makes it a versatile choice for designers seeking a dependable memory solution.  

The MSM548128BL-70GS-K is designed to meet stringent quality and reliability standards, ensuring stable operation across extended temperature ranges and demanding conditions. Its compact form factor and low-profile design further facilitate integration into space-constrained applications.  

For engineers and developers working on real-time processing, data buffering, or high-throughput systems, the MSM548128BL-70GS-K provides a balanced combination of speed, capacity, and efficiency, making it a practical choice for modern electronic designs.

Alternative Part Number

  • IS41C16256-70K --: Equivalent 256Kx16 fast page mode DRAM with 70ns access time, widely available and pin-compatible in the same SOJ package.
  • AS4C256K16-70JC --: Direct functional replacement for 256Kx16 FPM DRAM at 70ns, offered as a long-life legacy DRAM alternative to OKI parts.
  • HY51V16256C-70 --: 256Kx16 fast page mode DRAM with 70ns speed grade, suitable drop-in substitute for the OKI MSM548128 series.
  • IS41LV16256-50T --: 256K x 16-bit fast asynchronous SRAM with 50 ns access time, functionally similar to the 128K x 8 original and widely available as a drop-in style replacement.
  • CY7C1041CV33-10ZXC --: 256K x 16-bit asynchronous SRAM in a TSOP package with comparable speed grade, offering a robust alternative from a major SRAM vendor.
  • AS6C62256-55SIN --: 32K x 8 low-power CMOS SRAM with 55 ns access time, suitable for legacy designs needing a long-lifecycle replacement for older OKA SRAM parts.
