MX30LF2G28AD-XKI

Memory IC Overview

The MX30LF2G28AD-XKI is a 2Gb SLC NAND Flash memory device manufactured by Macronix. It features an x8 data bus width and operates within a voltage range of 2.7V to 3.6V. The device utilizes a 63-ball VFBGA package with dimensions of 9mm x 11mm. It supports ONFI 1.0 compliance and includes cache read capabilities for fast access. The memory array is organized into two planes, each containing 1024 blocks. Page size is 2048 bytes with 128-byte spare area, while block size is 128K bytes with 8K spare area.

Memory IC Feature Summary

• Supports ONFI 1.0 standard with multiplexed command, address, and data inputs.
• Features two-plane architecture enabling simultaneous program and erase operations.
• Includes hardware data protection via WP# pin and PT pin for chip-level locking.
• Provides secure OTP support and unique ID read functionality with PUF-like code structure.

Memory IC Applications

• Embedded system code storage
• Data storage in industrial applications
• Consumer electronics firmware retention

Memory IC Procurement Notes

Verify the specific ordering suffix XKI corresponds to the 63-ball VFBGA package and Industrial temperature grade (-40°C to +85°C). Confirm that the D suffix indicates the generation and 28A denotes the x8 mode A configuration. Ensure compatibility with host ECC requirements of 8-bit per (512+32) Byte as specified in the datasheet.

Memory IC Selection Notes

Select this component for designs requiring 2Gb capacity with x8 interface and single voltage operation. Consider the two-plane feature if parallel processing speed is needed. Verify that the 63-VFBGA package fits the PCB layout constraints. Check if the ONFI 1.0 compliance meets the controller's interface standards.

Memory IC Part Context

This part belongs to the MX30LFxG28AD family, which also includes 1Gb and 4Gb variants. All members share similar electrical characteristics and command sets but differ in density and page/block sizes. The XKI suffix specifically identifies the VFBGA package option within this series.

Memory IC Replacement Considerations

MX30LF1G28AD-XKI offers 1Gb capacity with identical package and interface. MX30LF4G28AD-XKI provides 4Gb capacity with the same form factor. Both are direct pin-compatible alternatives within the same product family.

Memory IC FAQ

What is the block protection mechanism?

Block protection is enabled by connecting the PT pin high at power-on, which protects the entire chip. Temporary or solid protection can be configured via BP bits using the Set Feature command.

How does the Cache Read operation work?

Cache Read allows first-byte read-access latency of 25us and sequential read of 20ns. The internal buffer preloads the next page during the current read cycle to reduce subsequent access times.
