TC58FVT321/B321FT/XB-70,-10
TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
32-MBIT (4M × 8 BITS / 2M × 16 BITS) CMOS FLASH MEMORY
DESCRIPTION
The TC58FVT321/B321 is a 33,554,432-bit, 3.0-V read-only electrically erasable and programmable flash memory
organized as 4,194,304 words × 8 bits or as 2,097,152 words × 16 bits. The TC58FVT321/B321 features commands
for Read, Program and Erase operations to allow easy interfacing with microprocessors. The commands are based on
the JEDEC standard. The Program and Erase operations are automatically executed in the chip. The
TC58FVT321/B321 also features a Simultaneous Read/Write operation so that data can be read during a Write or
Erase operation.
