Product details

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.

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.

The lifecycle status is listed as Active, but EPROM-based 80C51 MCUs have not been in high-volume factory production for years. 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.
