29F400TC-90PFTN TSOP-48 SMD CMOS Flash memory IC

From the shop's description

29F400TC-90PFTN TSOP-48 CMOS Flash memory SMD IC The 29F400TC-90PFTN TSOP-48 SMD is a 4 Mb (512K x 8 or 256K x 16) CMOS Flash Memory IC from Fujitsu, designed for reliable non-volatile storage in legacy electronic systems. It likely operates on a single 5V supply for read, write, and erase operations, eliminating the need for a separate programming voltage. With a 90ns access time, it is suitable for applications requiring moderate-speed data access. The IC is probably packaged in a 48-pin TSOP, ideal for surface mount technology, and is used in various applications requiring firmware or BIOS storage. Features: Single 5.0 V read, write, and erase. Boot Sector Architecture. Minimum 100,000 write/erase cycles. Temporary sector unprotection. Low Vcc write inhibit ≤ 3.2 V.
