TC58FVB800FT-80 – Parallel NOR Flash – Toshiba

The Toshiba TC58FVB800FT-80 is an 8 Mbit (1M x 8 / 512K x 16) 3V CMOS parallel NOR flash memory with a bottom boot-block architecture in a 48-pin TSOP package. This obsolete, hard-to-find device is stocked and available for RFQ.

The Toshiba TC58FVB800FT-80 is an 8 megabit (8 Mbit) CMOS parallel NOR flash memory from Toshiba’s legacy TC58FV 3-volt flash family. It is organized as 1,048,576 words × 8 bits or 524,288 words × 16 bits (1M x 8 / 512K x 16), with a software-selectable byte/word data bus. The “B” in the part number designates the bottom boot-block sector layout, making it well suited to microcontroller and embedded designs that place boot code at the low end of the address map. The device is supplied in a 48-pin TSOP package (“FT” suffix), and the “-80” suffix denotes the access-time speed grade.

As a member of Toshiba’s 3V (“FV”) flash line, the TC58FVB800FT-80 operates from a single low-voltage supply and offers in-system reprogrammability, sector erase, and standard parallel NOR flash command-set operation for reliable execute-in-place (XIP) code storage. This part is now obsolete / end-of-life and is no longer carried by authorized distributors, so it is sourced primarily through the independent-distribution channel.
