The Advanced Micro Devices AM27S21LM is a high-speed TTL-compatible Flash memory device organized as 256 words by 4 bits, offering a total density of 1 Kbit. This asynchronous device features a maximum access time of 60ns and operates across a wide temperature range of -55°C to 125°C. Housed in a 20-terminal ceramic quad flat pack (CQCC20), it is designed for demanding applications. Its robust construction and MIL-STD-883 Class C screening make it suitable for use in aerospace and defense systems, as well as industrial control and high-reliability computing platforms. The parallel interface and 5V nominal supply voltage ensure compatibility with established system architectures.
