S87C511

Microcontrollers Overview

The S87C511 is an 8-bit microcontroller based on the MCS-51 architecture, manufactured by Altera. It features a maximum operating speed of 16MHz and includes 4KB (4K x 8) of EPROM program memory. The device provides 128 bytes of RAM for data storage. It is housed in a 44-QFP package with dimensions of 10x10 mm and supports surface mount technology.

Microcontrollers Feature Summary

• Integrates 4KB of EPROM for non-volatile program storage within the MCS-51 architecture
• Supports surface mount mounting via a compact 44-QFP package
• Operates at clock speeds up to 16MHz for standard 8-bit processing tasks

Microcontrollers Applications

• Embedded control systems requiring MCS-51 compatibility
• Industrial automation controllers
• Consumer electronics logic circuits

Microcontrollers Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. Ensure the component matches the 44-QFP physical footprint. Confirm that the EPROM variant aligns with the required firmware programming capabilities. Cross-reference the manufacturer designation with Intel or Altera records to validate authenticity.

Microcontrollers Selection Notes

Select this component when an 8-bit MCS-51 core is required with integrated EPROM. Consider the 16MHz speed limit for timing constraints. Evaluate the 44-QFP package size against board space limitations. Compare RAM requirements against the 128-byte capacity available in this specific model.

Microcontrollers Part Context

This microcontroller belongs to the MCS-51 family, originally developed by Intel and later associated with Altera. It represents a legacy 8-bit architecture widely used in embedded applications. The S87C511 specifically denotes the EPROM version of this controller line.

Microcontrollers Replacement Considerations

Check for direct equivalents such as the 80C511 or other MCS-51 derivatives. Verify pin compatibility and memory configuration before substitution. Ensure the replacement supports the same voltage levels and interface requirements.
