FFF CompatibilityThe pin configuration conforms to the standard JEDEC 28-pin parallel memory layout, making it completely pin-compatible.Shares the same physical 28-pin DIP form factor (FDIP28W windowed ceramic or PDIP28).Electrically identical 512Kb CMOS EPROM with a matching 120ns access speed grade.
AI Summary

AT27C512R-12PC by Microchip Technology: EPROM - OTP Memory IC 512Kbit Parallel 120 ns 28-PDIP.

This classic STMicroelectronics alternative is an excellent drop-in match for legacy retro-computing or restoration projects.

  • Direct second-source equivalent from STMicroelectronics with matching 120ns access time
  • Features UV-erasability (windowed FDIP28W package) for reprogramming flexibility in prototyping
  • Direct pin-to-pin drop-in replacement in the same 28-pin socket
  • Obsolete product lifecycle (available primarily as surplus or legacy stock)
  • Standard ceramic package with quartz window requires UV light to erase, unlike one-time-programmable plastics

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
