CY7C472-40JI

The CY7C472-40JI is one of the CY7C472 series.The CYC47X FIFO series consists of high-speed, low-power,first-in first-out (FIFO) memories with programmable flags and retransmit mark. The CY7C470, CY7C472, and CY7C474 are 8K, 16K, and 32K words by 9 bits wide, respectively.They are offered in 600-mil DIP, PLCC, and LCC packages. Each FIFO memory is organized such  that the data is read in the same sequential order that it was written. Three status pins-Emp-ty/Full (E/F), Programmable Almost Full/Empty (PAFE), and Half Full (HF)-are provided to the user. These pins are de-coded to determine one of six states: Empty, Almost Empty,Less than Half Full, Greater than Half Full, Almost Full, and Full.

Features of the CY7C472-40JI are:(1)8K x 9, 16K x 9, and 32K x 9 FIFO buffer memory; (2)Asynchronous read/write; (3)High-speed 33.3-MHz read/write independent of depth/width; (4)Low operating power-ICC (max.) = 70 mA; (5)Programmable Almost Full/Empty flag; (6)Empty, Almost Empty, Half Full, Almost Full, and Full status flags; (7)Programmable retransmit; (8)Expandable in width; (9)5V ± 10% supply; (10)TTL compatible; (11)Three-state outputs; (12)Proprietary 0.8-micron CMOS technology.

The absolute maximum ratings of the CY7C472-40JI can be summarized as:(1)Storage Temperature:65°C to +150°C; (2)Ambient Temperature with Power Applied:55°C to +125°C;Supply Voltage to Ground Potential:0.5V to +7.0V; (3)DC Voltage Applied to Outputs in High Z State:0.5V to +7.0V;DC Input Voltage: 3.0V to +7.0V;Power Dissipation :1.0W; (4)Output Current, into Outputs (LOW):20 mA.If you want to know more information such as the electrical characteristics, please download the datasheet in www.seekic.com or www.chinaicmart.com.
