The Intel D27512 is a vintage 512-kilobit (64K x 8) Ultraviolet Erasable and Electrically Programmable Read-Only Memory (UV EPROM) chip first introduced in 1983. It features a distinctive quartz window on its ceramic package, which allows the storage cells to be cleared when exposed to intense UV light so the chip can be reprogrammed.
  • Memory Capacity: 512 Kbit organized as 64,384 words by 8 bits.
  • Package Form Factor: Standard 28-pin Ceramic Dual In-Line Package (CDIP / DIP-28).
  • Power Supply (Vcc): Requires a single standard 5.0V supply for read operations.
  • Programming Voltage (Vpp): Typically requires a 12.5V pulse for data writing operations.
  • Output Interface: Parallel interface with 3-state output characteristics for microcomputer bus compatibility.
  • This chip is a standard speed-rated which natively operates at 250 nanoseconds.
