CY7C433-25JI

The CY7C433-25JI is first-in first-out (FIFO) memories offered in 600-mil wide and 300-mil wide packages. Each CY7C433-25JI is organized such that the data is read in the same sequential order that it was written. Full and Empty flags are offered to stop overrun and underrun. Three additional pins are also offered to facilitate unlimited expansion i n width, depth, or both. The depth expansion technique steersthe charge signals from one device to another in par allel, thus cutting down the serial addition of propagation delays, so that throughput is not reduced. Data is steered in a similar manner.

Features of the CY7C433-25JI are:(1)asynchronous first-in first-out (FIFO) buffer memories;(2)dual-ported RAM cell;(3)high-speed 50.0-MHz read/write independent of depth/width;(4)low operating power: ICC = 35 mA;(5)empty and full flags (Half Full flag in standalone);(6)retransmit in standalone;(7)expandable in width.

The absolute maximum ratings of the CY7C433-25JI can be summarized as:(1):storage temperature ranges from65°C to +150°C;(2):ambient temperature with power applied is -55°C to +125°C;(3):supply voltage to ground potential is0.5V to +7.0V;(4):DC voltage applied to outputs in high Z state is0.5V to +7.0V;(5):DC input voltage is0.5V to +7.0V;(6):power dissipation is 1.0W;(7):output current, into outputs (LOW) is 20 mA;(8):static discharge voltage(per MILSTD883, Method 3015) is larger than 2000V;(9):latch-up current is greater than 200 mA.
