The Micron MT25QL256ABA8E12-1SIT TR is a 256 Mbit NOR Flash memory organized as 32M x 8 bits, communicating over an SPI interface with Quad I/O support at a clock frequency of 133 MHz. The Quad I/O capability allows four data lines to operate simultaneously, quadrupling the read throughput compared to single-bit SPI without adding extra package pins — a practical advantage when the MCU or FPGA bus is already pin-limited. The memory is non-volatile and retains data without power.
133 MHz clock — timing margin for the read path
The SPI clock frequency is 133 MHz. Page write cycle time is 2.8 ms; word write is 8 ms.
Package and mounting — 24-TBGA footprint
The device comes in a 24-ball Thin Ball Grid Array (24-TBGA) with a body size of 6 mm x 8 mm (supplier device package 24-T-PBGA). The BGA footprint requires a solder-paste stencil and reflow profile — not a hand-solderable package. Mounting is surface-mount only. The tape-and-reel (TR) and cut-tape (CT) options are available for volume pick-and-place or prototype quantities, respectively.
