Description
CY7C133 CY7C143 2K x 16 Dual-Port Static RAM .
The CY7C133 and CY7C143 are high-speed CMOS 2K by 16 dual-port static RAMs.
Features
* True dual-ported memory cells which allow simultaneous reads of the same memory location
* 2K x 16 organization
* 0.65-micron CMOS for optimum speed/power
* High-speed access: 25/35/55 ns
* Low operating power: ICC = 150 mA (typ. )
* Fully asynchronou
Applications
* requiring shared or buffered data, such as cache memory for DSP, bit-slice, or multiprocessor designs. Each port has independent control pins; Chip Enable (CE), Write Enable (R/WUB, R/WLB), and Output Enable (OE). BUSY signals that the port is trying to access the same location currently being acces
