Advanced Micro Devices AM27S31AFMB is a 32K x 8 OTP ROM with a 45ns access time, designed for high-reliability applications. This TTL-compatible device offers 262,144 bits of non-volatile storage in a 24-lead ceramic flatpack (CDFP24). Operating asynchronously, it supports a supply voltage range of 4.5V to 5.5V with a nominal 5V requirement. The component is rated for operation across an extended temperature range of -55°C to +125°C, meeting MIL-STD-883 Class B (Modified) screening standards. Its surface-mount configuration with a 1.27mm terminal pitch makes it suitable for dense board layouts. Applications include aerospace, defense, and industrial systems requiring robust, radiation-tolerant memory solutions.
