T25S80 (8Mbit) serial flash memory supports standard Serial Peripheral Interface (SPI) and dual/four SPI: serial clock, chip selection, serial data I/O0 (SI), I/O1 (SO), I/O2 (WP #), I/O3 (HOLD #). The transmission speed of dual input/O data is 266Mbit/s, and the transmission speed of four input/O data is 532Mbit/s.

8MB serial flash memory
-1024K bytes
-256 bytes per programmable page
Standard, dual channel, four-way SPI

-Dual SPI: SCLK, CS #, IO0, IO1, WP #, HOLD#
-Four SPI channels: SCLK, CS #, IO0, IO1, IO2, IO3
High speed clock frequency
-133MHz for fast reading of 30PF load
-Dual I/O data transmission can reach up to 266Mbits/s
-Four channel I/O data transmission, up to 532Mbit/s
Software/hardware write protection
-Write protect all/part of the memory through software
-Enable/disable protection using WP # pin
-Top/bottom block protection
Durability and data retention
-At least 100000 programming/erasing cycles
-Typical 20-year data retention period
Allow XiP (on-site execution) operations
-High speed reading reduces the total acquisition time of XiP instructions
-Continuous reading with Wrap further reduces data latency for filling SoC cache
