DESCRIPTION

The A25Q128 is 128M-bit Serial Peripheral

Interface (SPI) Flash memory, and supports the

Dual/Quad SPI: Serial Clock, Chip Select, Serial

Data I/O0 (SI), I/O1 (SO), I/O2 (/WP), and I/O3

(/HOLD). The Dual I/O data is transferred with

speed of 240Mbits/s and the Quad I/O & Quad

output data is transferred with speed of 480Mbits/s.

The device uses a single low voltage power supply,

ranging from 2.7 Volt to 3.6 Volt.

Additionally, the device supports JEDEC standard

manufacturer and device ID and three 256-bytes

Security Registers.

The A25Q128 is available in SOP8, DFN8(5x6) and

SOP16 packages.
