Description
This is a summary of the electronic component model C025, which falls under the product category of IC chips. The CY7C024/0241 and CY7C025/0251 are low-power CMOS 4K x 16/18 and 8K x 16/18 dual-port static RAMs. This model has various arbitration schemes to handle situations when multiple processors access the same piece of data. It has two ports that allow independent, asynchronous access for reads and writes to any location in memory.
Specifications and features
- True Dual-Ported memory cells which allow simultaneous reads of the same memory location
- 4K x 16 organization (CY7C024)
- 4K x 18 organization (CY7C0241)
- 8K x 16 organization (CY7C025)
- 8K x 18 organization (CY7C0251)
- 0.65-micron CMOS for optimum speed/power
- High-speed access: 15 ns
- Low operating power: ICC = 150 mA (typ.)
- Fully asynchronous operation
- Automatic power-down
- Expandable data bus to 32/36 bits or more using Master/Slave chip select when using more than one device
- On-chip arbitration logic
- Semaphores included to permit software handshaking between ports
- INT flag for port-to-port communication
- Separate upper-byte and lower-byte control
- Pin select for Master or Slave
- Available in 84-pin PLCC and 100-pin TQFP
Application Scenarios
The C025 model IC chips are ideal for use in devices with multiple processors that require asynchronous access to memory. Some examples of such devices are embedded systems and networking equipment.
