Overview
The Advanced Micro Devices 67C4033-10N is an asynchronous FIFO memory component organized as 64 words by 5 bits. It operates at a maximum data rate of 10MHz with a supply voltage range of 4.5V to 5.5V and a maximum supply current of 35mA. The device supports uni-directional bus communication and functions within an operating temperature range of 0°C to 70°C. It is housed in a 20-pin dual in-line package (PDIP) designed for through-hole mounting.
Feature Summary
- Asynchronous first-in-first-out buffering architecture
- Uni-directional data transfer capability
- CMOS RAM-based high-performance design
Applications
- High-speed data buffering between disparate clock domains
- Interface bridging in digital logic systems
- Temporary data storage in microprocessor applications
Procurement Notes
Verify the specific bit-width configuration, as some sources indicate 8-bit variants exist for this base part number. Confirm the 20-DIP package availability and ensure the 10MHz speed grade matches system timing requirements. Check for RoHS compliance status and confirm the manufacturer origin given the transition from Advanced Micro Devices to AMD/GlobalFoundries.
Selection Notes
Select this component when a small-capacity, uni-directional asynchronous buffer is required. Ensure the system voltage aligns with the 4.5V to 5.5V range. Consider the 64-word depth sufficient for the intended latency needs. Verify that the 10MHz maximum frequency meets the interface speed requirements without exceeding the specified limits.
Part Context
This part belongs to the 67C4033 series of CMOS FIFO memories. It represents a legacy product line originally developed by Advanced Micro Devices. The device serves as a standard solution for simple buffering tasks in older or specialized industrial control systems requiring reliable asynchronous data handling.
Replacement Considerations
Direct substitutes may include other 64x5 or 64x8 asynchronous FIFOs from manufacturers like Texas Instruments or ON Semiconductor. Verify pin compatibility and electrical specifications before substitution. Note that newer generations may offer higher speeds or different packaging options.
