ST M28W160BT M28W160BB 16 Mbit (1Mb x16 Boot Block) Low Voltage Flash Memory handbook(1)
The M28W160BT and M28W160BB are 16 Mbit (1 M × 16) low‑voltage flash memory devices offered in TSOP48 and UBGA46 packages. The document provides a detailed description of the memory architecture, electrical specifications, pin functions, and supported commands such as read, program, erase, and CFI query.
Key features include a supply voltage range of 2.7 V–3.6 V (optional 12 V for fast programming), up to 100 000 program/erase cycles per block, 20 years data retention, and a total of 39 memory blocks with separate parameter and main blocks. The handbook also outlines device operations, timing, and status register usage.
