AM29C334-2/BZC

Shift Registers Overview

The AM29C334-2/BZC is a specialty memory circuit manufactured by Rochester Electronics, originally designed by Advanced Micro Devices. It functions as a multi-port SRAM with a density of 1152 bits, organized as 64 words by 18 bits. The device operates asynchronously and features two elements with four bits per element. It is housed in a 120-pin ceramic PGA package (CPGA120) with through-hole mounting. The component supports an operating temperature range from -55°C to 125°C and has a typical access time of 40ns.

Shift Registers Feature Summary

• Multi-port SRAM architecture providing simultaneous access capabilities
• Asynchronous operation mode for flexible timing integration
• Ceramic PGA packaging suitable for high-reliability environments

Shift Registers Applications

• High-performance computing systems requiring fast data access
• Industrial control applications operating in extreme temperatures
• Military and aerospace electronic equipment

Shift Registers Procurement Notes

Verify the manufacturer designation, as this part is currently produced by Rochester Electronics under license. Confirm the specific suffix indicates the correct temperature grade and package variant. Ensure compatibility with existing 120-PGA footprints. Request detailed datasheets to validate electrical characteristics against original AMD specifications before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when asynchronous multi-port memory functionality is required within a ruggedized environment. The ceramic PGA package offers superior thermal stability compared to plastic alternatives. Consider the 18-bit word width for specific data bus architectures. Verify that the 40ns access speed meets system timing requirements for the intended application frequency.

Shift Registers Part Context

This component belongs to the AM29C334 series of specialty memory circuits. It represents a legacy design originally developed by Advanced Micro Devices, now maintained by Rochester Electronics for long-term supply. The series is characterized by its multi-port capabilities and robust construction, targeting niche markets where standard commercial components are insufficient.

Shift Registers Replacement Considerations

Direct substitutes include other AM29C334 variants with compatible pinouts. Verify functional equivalence regarding port configuration and access times. Cross-reference with Rochester Electronics' current production lists for updated revision levels.
