The Advanced Micro Devices AM27LS185LM is a 2048-bit (512 x 4) One-Time Programmable (OTP) Read-Only Memory (ROM) device. This component operates asynchronously with a maximum access time of 70ns. It features a TTL compatible interface and a parallel input/output organization. The device is housed in a 28-lead Ceramic Quad Flatpack (CQCC) package with a rectangular shape and quad terminal positioning. Designed for operation across a wide temperature range, from -55°C to +125°C, it supports a supply voltage of 4.5V to 5.5V, with a nominal voltage of 5V. Typical applications for this type of memory component include embedded systems, industrial controls, and legacy system designs requiring high reliability and specific memory configurations. The AM27LS185 series is known for its robust performance in demanding environments.
