Description
The BY25D80 is 8M-bit Serial Peripheral Interface (SPI) Flash memory, and supports the Dual SPI:
Serial Clock, Chip Select, Serial Data I/O0 (SI), I/O1 (SO). The Dual Output data is transferred
with speed of 108Mbits/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.
In order to meet environmental requirements, Boya Microelectronics offers an 8-pin SOP 150-mil,
173-mil or 208mil, an 8-pad USON 3x3-mm, an 8-pin USON 3x2-mm and other special order
packages, please contacts Boya Microelectronics for ordering information.
