The MT28F400B3SG-8 BET is a 4Mbit flash memory device from Quarktwin Technology Ltd., organized as 256K x 16 or 512K x 8. It features seven separately erasable blocks, including a 16KB boot block that is hardware-protected to prevent accidental erasure. The device operates at a supply voltage of 3.3V for all operations, with programming capabilities using either 3.3V or 5V VPP. It supports an access time of 80ns and is designed for high endurance with up to 100,000 erase cycles. The memory is packaged in a 48-pin TSOP Type I configuration, making it suitable for various applications requiring nonvolatile storage. The device is compatible with industry-standard pinouts and is fully TTL-compatible for inputs and outputs.
