IS25LP128F-RMLA3-TR

IS25LP128F-RMLA3-TR is a high-density SPI serial flash memory from ISSI (IS25LP family). It provides non-volatile storage for firmware and data in embedded systems.
Key points:
- Capacity: 128 Megabits (16 MB).
- Interface: SPI-compatible, low-voltage operation (typically 2.7–3.6 V) with fast read support.
- Performance: High-speed read (up to the device’s rated MHz), page programming, and sector/block erase operations.
- Organization and memory map: Common sector sizes (e.g., 4 KB sectors; larger blocks for erasure); typical page sizes around 256 bytes.
- Features: Standard security and protection features (status register, write protection, power-down modes, etc.), suitable for firmware boot code and application data.
- Package/packing: RMLA3 denotes the specific package variant; -TR indicates tape-and-reel shipping.
Notes:
- Exact timing, commands, and packaging details (pinout, pin assignments, voltage range) are in the ISSI IS25LP128F datasheet. Check the datasheet for the precise package and electrical characteristics of the RMLA3-TR variant.
