FFF CompatibilityThe physical footprint and JEDEC standard pinout are identical to the original CY62256NLL-70PXC in the 28-pin 600-mil PDIP package.Matches the physical 28-pin plastic dual in-line package (PDIP) with 600-mil row spacing.The electrical characteristics meet or exceed the original, including a faster 55 ns access time and wide 2.7V to 5.5V supply voltage range.Maintains the exact same JEDEC 28-pin 600-mil PDIP pinout and footprint for direct board mounting.Perfect physical physical duplicate in 28-PDIP.Exceeds original requirements by offering wider industrial operating temperature limits alongside faster performance.
AI Summary

CY62256NLL-70PXC by Infineon Technologies: SRAM - Asynchronous Memory IC 256Kbit Parallel 70 ns 28-PDIP.

The AS6C62256-55PCN is a high-confidence, active drop-in replacement specifically designed to succeed obsolete JEDEC-standard 256K SRAMs. It operates over the same commercial temperature range of 0°C to 70°C and features ultra-low standby power consumption.

  • Direct drop-in replacement with JEDEC standard 28-pin 600-mil PDIP package.
  • Slightly faster access time of 55 ns compared to the original 70 ns.
  • Wider voltage supply range of 2.7V to 5.5V (covers original 4.5V to 5.5V).

The AS6C62256-55PIN is the industrial-grade sibling of the 55PCN, offering an extended temperature range of -40°C to +85°C. It serves as an excellent upgrade for designs operating in harsher environments.

  • Direct drop-in replacement with identical package and pin assignments.
  • Extended industrial temperature range of -40°C to +85°C compared to original 0°C to 70°C.
  • Slightly faster access speed of 55 ns vs 70 ns.

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.

Frequently asked questions

Yes. The Infineon Technologies CY62256NLL-70PXC is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
