ZB25D20

The ZB25D20A/10A of non-volatile flash memory device supports the standard Serial Peripheral Interface (SPI). Traditional SPI single bit serial input and output (Single I/O or SIO) is supported as well as optional two bit (Dual I/O or DIO) serial protocols. This multiple width interface is called SPI Multi-I/O or MIO.


The SPI protocols use only 4 signals:
Chip Select (CS#)
Serial Clock (CLK)
Serial Data
- IO0 (DI)
- O1 (DO)

The ZB25D20A/10A support the standard Serial Peripheral Interface (SPI) and Dual Output SPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), O1 (DO). SPI clock frequencies of up to 100MHz are supported allowing equivalent clock rates of 200MHz (100MHz x 2) for Dual Output when using the Fast Read Dual Output. These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories.
The ZB25D20A/10A provides an ideal storage solution for systems with limited space, signal connections, and power. These memories' flexibility and performance is better than ordinary serial flash devices. They are ideal for code shadowing to RAM, executing code directly (XIP), and storing reprogrammable data.
