BY25Q80A Description
1. Description
The BY25Q80A is 8M-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, 173-mil or 208mil, an 8-pad WSON 6x5-mm, an 8-pin USON 3x3-mm, and other special order packages, please contacts Boya Microelectronics for ordering information. Figure 1. Logic diagram
