/Boyamicro 4M SOP8 BY25Q40ASSIG Flash

Boyamicro 4M SOP8 BY25Q40ASSIG Flash

The BY25Q40A is 4M-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 216Mbits/s and the Quad I/O & Quad output  data is transferred with speed of 432Mbits/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 an 8-pin SOP 150-mil,  or 208mil, an 8-pin TSSOP 173-mil, an 8-pad USON 3x2-mm, and other special order packages,  please contacts Boya Microelectronics for ordering information.
