Advanced Micro Devices AM27S40ALM is a 4096-bit (512 x 8) One-Time Programmable Read-Only Memory (OTP ROM) device. This component features a maximum access time of 12ns and operates with TTL logic levels. The memory organization is 512 words by 8 bits. The AM27S40ALM is housed in a 28-terminal Ceramic Quad Flat-Pack (CQCC) package with a rectangular shape and quad terminal positions. It supports a parallel interface and operates across a wide temperature range from -55°C to +125°C. The device requires a supply voltage between 4.5V and 5.5V, with a nominal value of 5V, and has a maximum supply current of 170mA. This component is suitable for applications requiring non-volatile program storage within demanding environments, including aerospace and defense systems, given its MIL-STD-883 Class C screening level.
