With a 200 ns access time, it fits into legacy 8-bit microprocessor and microcontroller systems where the bus timing expects a 200 ns or slower memory cycle — a 10 MHz 8086 with 4 wait states, for example, or a 68000 running at 8 MHz with the DTACK line stretched. ## Active production, RoHS non-compliant The part is RoHS non-compliant (lead-bearing solder balls / die-attach), so it is exempt from the RoHS directive for certain applications or intended for repair / legacy-support builds where the exemption applies. ## Bulk tube delivery Shipped in bulk tubes (anti-static PDIP rails) — no tape-and-reel option. The 28-pin PDIP footprint is a 0.600-inch wide body, 0.100-inch pitch, compatible with standard DIP sockets or wave-solder through-hole assembly.","metaTitle":"TMS27PC256-2NL OTP ROM, 32Kx8, 200ns PDIP28","metaDescription":"Texas Instruments TMS27PC256-2NL OTP ROM, 32Kx8, 200ns access, PDIP28.
