There are 256, 512, 1,024, 2,048, and 4,096 words respectively by 9 bits wide. Each FIFO memory is organized such that the data is read in the same sequential order that it was written. Full and empty flags are provided to prevent overrun and underrun. Three additional pins are also provided to facilitate unlimited expansion in width, depth, or both. The depth expansion technique steers the control signals from one device to another in parallel. This eliminates the serial addition of propagation delays, so that throughput is not reduced. Data is steered in a similar manner. The read and write operations may be asynchronous each can occur at a rate of 50 MHz. The write operation occurs when the write W signal is LOW. Read occurs when read R goes LOW. The nine data outputs go to the high impedance state when R is HIGH. A Half Full HF output flag that is valid in the standalone and width expansion configurations is provided. In the depth expansion configuration, this pin provides the expansion out XO information that is used to tell the next FIFO that it is activated. In the standalone and width expansion configurations, a LOW on the retransmit RT input causes the FIFOs to retransmit the data. Read enable R and write enable W must both be HIGH during retransmit, and then R is used to access the data. The CY7C419, CY7C420, CY7C421, CY7C424, CY7C425, CY7C428, CY7C429, CY7C432, and CY7C433 are fabricated using an advanced 0.65-micron P-well CMOS technology. Input ESD protection is greater than 2000V and latch-up is prevented by careful layout and guard rings. • San Jose, CA 95134-1709 • 408-943-2600 [+] Feedback Pin Configurations Figure 32-Pin PLCC/LCC CY7C419/21/25/29/33 Figure 32-PIn TQFP Figure 28-Pin DIP Table Selection Guide 4K x 9 Frequency MHz Maximum Access Time ns ICC1 mA Page 2 of 17 [+] Feedback CY7C419/21/25/29/33 Maximum Rating Exceeding maximum ratings may impair the useful life of the device.
