Description

This article describes the Electronic Component Model CY7C133-25JC, which belongs to the IC Chips category. It is a high-speed CMOS 2K by 16 dual-port static RAM and can be used as a standalone 16-bit dual-port static RAM or as a master dual-port RAM in conjunction with the CY7C143 slave dual-port device in systems requiring 32-bit or greater word widths.

Specifications and 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 asynchronous operation
• Master CY7C133 expands data bus width to 32 bits or more using slave CY7C143
• BUSY output flag on CY7C133; BUSY input flag on CY7C143
• Available in 68-pin PLCC

Application Scenarios

The CY7C133-25JC is suitable for various applications that require shared or buffered data, such as cache memory for DSP, bit-slice, or multiprocessor designs.

Comparison

• True dual-ported memory cells provide simultaneous reads of the same memory location.
• Low operating power of ICC = 150 mA (typ.)
• Fully asynchronous operation.

• Not suitable for applications that do not require dual-port operation and shared data.
