Product details

What this part is and where it lands

The Intel 5962-9169702MUA is an 8-bit MCU from the M87C51FC series, built around the 80C51 core. It runs at 16 MHz, has 32 I/O lines, a serial port, and an internal oscillator. The program memory is EPROM — UV-erasable, factory-programmed, no field updates. Rated for -55 to 125°C, this is a military-temperature device meant for avionics, missile guidance, satellite, or downhole environments where the board sees extreme thermal cycling.

EPROM: no field updates possible

The program memory is EPROM. Code is written at the factory or in a UV-erasable windowed package. This bulk part is OTP. Once programmed, the firmware is locked.

Sourcing and lifecycle reality

The lifecycle status is listed as Active, but EPROM-based 80C51 MCUs have not been in high-volume factory production for years. This part is sourced through independent distribution channels, not direct from Intel. Availability and current pricing are confirmed at quote time against an RFQ. For dual-sourcing, the 5962-9169701MUA (12 MHz) is a pin-compatible second source if the speed difference is acceptable.

Frequently asked questions

When sourcing 5962-9169702MUA, what's the closest functional second-source — 5962-9169701MUA?

Yes, the 5962-9169701MUA is the closest functional second source. It shares the same M87C51FC die, 32 I/O, EPROM, -55 to 125°C range, 2.7 V supply, and surface-mount package — only the clock speed differs (12 MHz vs 16 MHz). It drops in without rewiring.

Will 5962-9169702MUA drop into a panel that was specified around 5962-9169701MUA without rewiring?

Yes, it drops in without rewiring. The 5962-9169701MUA and 5962-9169702MUA share the same die, package, I/O count, supply voltage, and temperature range. The only difference is the clock speed: 12 MHz on the 01, 16 MHz on the 02. The firmware will run faster, but the PCB layout and BOM footprint are identical.
