JS27HP4G08SDDA-45M-SU

Memory IC Overview

The JS27HP4G08SDDA-45M-SU is a 4 Gbit NAND Flash memory featuring an x8 I/O interface and 1.8V supply voltage (1.7V to 1.95V). It utilizes a 63-Ball FBGA package measuring 9.0 x 11.0 mm. The device supports ONFI 1.0 commands, includes 4-bit ECC for 528 bytes, and offers 100,000 program/erase cycles with 10-year data retention. Operating temperature ranges from -40°C to +105°C.

Memory IC Feature Summary

• Supports Copy Back Program for fast data rewriting without external buffering
• Includes internal ECC for 4-bit error correction per 528 bytes
• Features hardware write protection via the WP pin
• Provides Cache Read functionality to improve read throughput

Memory IC Applications

• Solid state mass storage applications
• Automotive Grade 2 embedded systems
• Industrial control data logging

Memory IC Procurement Notes

Verify that the specific suffix 'M' confirms Automotive Grade 2 classification (-40°C to +105°C) rather than Industrial grade. Ensure the 1.8V power rail strictly adheres to the 1.7V to 1.95V range. Confirm the x8 bus width matches the system controller's interface capabilities before finalizing procurement.

Memory IC Selection Notes

Select this component when a 4 Gbit density with x8 parallel interface is required. The 1.8V Vcc specification distinguishes it from 3.3V variants. Verify compatibility with ONFI 1.0 command sets. Consider the 63-FBGA footprint constraints during PCB layout design.

Memory IC Part Context

This part belongs to the JSC NAND Series by Jeju Semiconductor Corp. It shares pinout compatibility with other densities in the family, facilitating migration between different storage capacities without rearranging the board footprint.

Memory IC Replacement Considerations

Cross-reference with JS27HU4G08SDDA-25M-SU if 3.3V operation is needed instead of 1.8V. Check JS27HP4G16SDDA-45M-SU if a wider x16 interface is preferred.
