Micron Technology, Inc. Memory RC28F128J3F75F

The RC28F128J3F75F is a 128 Mbit NOR Flash memory device from Quarktwin Technology Ltd., featuring a symmetrical architecture with 128 blocks of 1 Mbit each. It operates with an initial access speed of 75 ns and supports 25 ns asynchronous page-mode reads. The device includes a 256-word write buffer for x16 mode and a 256-byte write buffer for x8 mode, with an effective programming time of 1.41 µs per byte. This memory operates within a system voltage range of 2.7 V to 3.6 V and is available in two packaging options: a 56-lead TSOP and a 64-ball Easy BGA package. Enhanced security features include individual block locking, password access, and a one-time programmable register with 64 bits for unique information. The device supports program and erase suspend operations and is compatible with the Common Flash Interface (CFI). The RC28F128J3F75F is designed for a wide operating temperature range of -40 °C to +85 °C and offers a minimum of 100,000 erase cycles per block, ensuring reliability for embedded applications.
