IS26KS256S-DPBLI00

Memory IC Overview

The IS26KS256S-DPBLI00 is a 256 Mbit HyperFlash NOR memory device manufactured by ISSI. It features a synchronous parallel interface with an 8-bit data bus and operates at a maximum clock frequency of 166 MHz. The component supports a supply voltage range of 1.7 V to 1.95 V and utilizes a 24-pin TFBGA package measuring 6x8 mm. It offers a 32M x 8 organization and maintains an active read current of up to 180 mA. The device is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Supports high-speed synchronous parallel access via the HyperFlash interface architecture
• Provides sustained read throughput through double-data rate (DDR) transfer capabilities
• Operates on a single 1.8V power supply with CMOS I/O levels

Memory IC Applications

• Code execution in place (XIP) applications requiring fast boot times
• Storage of firmware and operating system images in embedded systems
• Data logging and configuration storage in industrial control units

Memory IC Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is associated with ISSI rather than Spansion. Confirm that the 24-VFBGA footprint matches your PCB layout constraints. Ensure the 1.8V core voltage requirement aligns with your system's power rails. Check for RoHS compliance status if environmental regulations apply to your deployment region.

Memory IC Selection Notes

Select this component when a parallel interface is required for direct code execution without complex controller overhead. The 166 MHz clock speed suits applications needing rapid random access to small code segments. Consider the 24-pin package size for space-constrained designs where serial flash alternatives would require additional GPIO pins for multiplexing.

Memory IC Part Context

This device belongs to the IS26KS256S series of HyperFlash memories. While often compared to Spansion S26KL series devices due to functional similarities, it is distinctively branded under ISSI. The technology leverages advanced NAND-like density with NOR-like flexibility, targeting cost-sensitive embedded markets requiring high performance.

Memory IC Replacement Considerations

The S26KL256S-10HNVI from Cypress/Infineon serves as a pin-compatible alternative within the same HyperFlash family. Verify that the replacement supports the same 1.8V supply and 166 MHz timing requirements before substitution.
