8 Mbit CUI flash in a 48-UBGA — what this part is for
The Intel GT28F800B3T120 is an 8 Mbit (512K x 16) non-volatile flash memory from the ETOX™ series, organised as a Common-Use Interface (CUI) device. It delivers a 120 ns access time and operates from a 2.7 V supply, making it suited for low-voltage embedded systems — code shadowing in telecom line cards, firmware storage in industrial controllers, or configuration memory in networking equipment where the bus must match a slow host without wait states. The industrial temperature range (-40°C to 85°C) covers outdoor base stations and factory-floor PLCs.
120 ns access time — bus timing fit
The 120 ns access time sets the read-cycle window the host controller must meet. A 110 ns variant (GT28F800B3T110) exists in the same footprint and voltage rail.
Active lifecycle — no LTB pressure
The GT28F800B3T120 carries an Active product status. No last-time-buy notice, no NRND flag. For a BOM line that needs this exact density and voltage, that means the manufacturer is still running the part — no forced redesign, no date-code scavenging. The 165 µs word/page write cycle time is typical for this generation; plan the programming throughput accordingly.
