AM9516A-6JC

Overview

The AM9516A-6JC is a dual-channel DMA controller manufactured by Advanced Micro Devices. It operates with a maximum clock frequency of 6.06 MHz and utilizes MOS technology. The device features a 24-bit address bus width and an external data bus width of 16 bits, supporting compatibility with the Intel 8086 and Motorola 68000 architectures. It is housed in a 48-pin ceramic DIP package (CDIP48) with side-brazed termination. The component requires a 5 V power supply and functions within an operating temperature range of -55 °C to +70 °C.

Feature Summary

• Supports direct memory access operations for two independent channels
• Provides hardware compatibility with standard 16-bit microprocessor buses
• Utilizes ceramic packaging for robust thermal and mechanical stability

Applications

• Data transfer management in 8086-based computer systems
• Peripheral interface control in 68000 architecture environments
• High-speed I/O buffering in industrial embedded controllers

Procurement Notes

Verify the specific suffix 'JC' against official AMD documentation to confirm exact temperature grade and package variant. Ensure compliance with RoHS directives if required, as historical components may not meet current environmental standards. Confirm pinout alignment with target PCB layout before integration.

Selection Notes

Select this component when interfacing legacy 16-bit processors requiring dedicated DMA handling. Compare performance metrics against newer integrated solutions if system size or power consumption are critical constraints. Validate that the 6.06 MHz speed meets the timing requirements of the connected peripheral devices.

Part Context

This part belongs to the AMD 9516 series of DMA controllers, designed for high-performance data movement in early personal computers and workstations. It serves as a standalone peripheral chip often paired with CPU modules like the 8086 or 68000 to offload data transfer tasks from the main processor.

Replacement Considerations

Direct pin-compatible replacements are limited due to the specific vintage of the component. Consider functional equivalents from other manufacturers offering 16-bit DMA controllers with similar bus widths and channel counts, ensuring voltage levels and timing parameters match.
