5962-9169702MUA

Overview

The Altera 5962-9169702MUA is a military-grade 8-bit microcontroller based on the M87C51FC architecture. It features an 80C51 CPU core with a maximum operating frequency of 16 MHz. The device integrates 32 KB (32K x 8) of One-Time Programmable Read-Only Memory (OTPROM). This component is designed for high-reliability applications requiring robust processing capabilities within a compact form factor.

Feature Summary

• Integrates an 80C51 CPU core for standard 8-bit instruction set compatibility
• Includes 32 KB of non-volatile OTPROM for permanent code storage
• Supports clock speeds up to 16 MHz for efficient data processing

Applications

• Military and aerospace embedded control systems
• High-reliability industrial automation controllers
• Secure hardware modules requiring fixed firmware

Procurement Notes

Verify that the specific part number corresponds to the M87C51FC derivative, as commercial equivalents may differ in memory type or voltage specifications. Confirm that the OTPROM nature of the device aligns with the project's requirement for non-updatable firmware, as this characteristic prevents post-manufacturing code modifications. Ensure environmental ratings meet the intended operational temperature range.

Selection Notes

Select this component when a hardened 80C51-compatible architecture is required for mission-critical environments. It is suitable for designs where firmware must remain immutable after production. Consider the trade-off between the fixed memory capacity and the need for future updates, as OTPROM does not support reprogramming. Evaluate if the 16 MHz performance ceiling meets the real-time processing demands of the target application.

Part Context

This part belongs to the broader family of Altera (now Intel) military-grade programmable logic and microcontroller products. These components are characterized by enhanced reliability standards and extended temperature ranges compared to commercial variants. The 5962 prefix indicates compliance with MIL-PRF-38534 or similar military procurement specifications, ensuring rigorous quality control and traceability for defense and space applications.
