MX29F800CBTI-70G

Memory IC Overview

The MX29F800CBTI-70G is an 8-megabit (1M x 8 or 512K x 16) single-voltage NOR flash memory manufactured by Macronix. It operates on a 4.5V to 5.5V supply and features a 70ns access time. The device utilizes a 48-pin TSOP package with a bottom boot sector architecture, consisting of sectors sized at 16KB, 8KB, 32KB, and multiple 64KB blocks. It supports asynchronous parallel interfaces, hardware sector protection, and includes Ready/Busy status outputs.

Memory IC Feature Summary

• Supports switchable 8-bit or 16-bit data bus widths for flexible system integration
• Features a dedicated bottom boot sector configuration for reliable code execution storage
• Provides hardware-based sector protection mechanisms to prevent accidental programming or erasure
• Includes embedded write state controllers for automatic program and erase algorithm management

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Industrial control applications needing sector protection
• Consumer electronics utilizing single voltage power supplies
• Automotive infotainment modules operating within industrial temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'BTI' confirms the Bottom Boot Sector layout, 48-pin TSOP physical package, and Industrial temperature grade (-40°C to +85°C). Ensure the '-70' designation matches the required 70ns timing specification for your target interface speed. Confirm RoHS compliance status aligns with current manufacturing standards before finalizing orders.

Memory IC Selection Notes

Select this component when a fixed 5V supply environment is available and a bottom-start boot block is necessary for firmware placement. Compare against top-boot variants if address mapping requirements differ. Consider the 48-pin TSOP footprint constraints during PCB layout design. Verify that the 70ns access speed meets the processor's maximum clock cycle requirements without adding wait states.

Memory IC Part Context

This part belongs to the MX29F series of single-voltage NOR flash memories from Macronix. It shares architectural similarities with other devices in the family but is distinguished by its specific 8Mb capacity and bottom boot sector arrangement. The TSOP-48 package offers a compact surface-mount solution suitable for space-constrained electronic designs requiring robust data retention.
