CY7C141-25JXC

Memory IC Overview

The CY7C141-25JXC is a 1K x 8 dual-port static RAM manufactured by Infineon Technologies. It features true dual-ported memory cells allowing simultaneous reads of the same location. The device operates at a maximum access time of 25 ns with fully asynchronous operation and automatic power down capabilities. It utilizes 0.65 micron CMOS technology for optimized speed and power consumption, supporting a maximum operating current of 110 mA. The component is housed in a 52-pin Pb-free Plastic Leaded Chip Carrier (PLCC) package.

Memory IC Feature Summary

• True dual-ported memory architecture enabling independent access to any memory location from two ports simultaneously.
• Integrated BUSY output flag on the master port to signal contention when accessing locations currently accessed by the other port.
• INT flag functionality for port-to-port communication, indicating data placement in unique interrupt locations.
• Automatic power down feature controlled independently on each port via chip enable pins.

Memory IC Applications

• Cache memory implementations for digital signal processors
• Bit-slice processor designs requiring shared data buffers
• Multi-processor systems utilizing buffered data exchange

Memory IC Procurement Notes

Verify the specific ordering suffix JXC confirms the 52-pin Pb-free PLCC package configuration. Confirm the commercial temperature range specification aligns with system requirements. Ensure compatibility with existing 5V logic levels and check for end-of-life status through official Infineon channels before finalizing procurement plans.

Memory IC Selection Notes

Select this component for applications requiring high-speed asynchronous dual-port memory with independent control pins. The device supports expansion to wider data buses when paired with slave devices like the CY7C140 series. Consider the integrated arbitration logic and interrupt flags for complex multi-master environments without external buffering components.

Memory IC Part Context

This part belongs to the CY7C130/131/140/141 family of 1K x 8 dual-port SRAMs. The CY7C141 variant functions as a slave device in expanded configurations, accepting BUSY inputs rather than generating them. It shares architectural similarities with the CY7C131 master device but differs in pin definitions regarding arbitration signals.

Memory IC Replacement Considerations

CY7C141-25JC serves as a standard leaded alternative within the same speed grade. CY7C141-25NC provides a plastic quad flatpack option. Verify package dimensions and pinout compatibility before substituting with these variants or other speed grades in the CY7C141 series.
