1.
Description
The BY25Q32BS is 32M-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.
In order to meet environmental requirements, Boya Microelectronics offers 8-pin SOP 208mil,
8-pad WSON 6x5-mm, and other special order packages, please contacts Boya Microelectronics
for ordering information.
