Texas Instruments TMS29F400B-90CDCDQ is a 4-Mbit Flash memory organized as 256K x 16 bits. This NOR Flash device offers a maximum access time of 90 nanoseconds and operates from a single 5V supply. It features a 16-bit data bus, with an alternate 8-bit bus capability for flexible system integration. The memory is partitioned into sectors for efficient block erasure, including boot blocks. Key features include Command User Interface, Data Polling, Ready/Busy output, and Toggle Bit functionality for status monitoring. The TMS29F400B is housed in a 48-lead TSSOP package with a 0.5mm terminal pitch, suitable for surface mounting. It supports a wide operating temperature range of -40°C to 125°C and exhibits an endurance of 100,000 program/erase cycles. This component finds application in automotive, industrial, and consumer electronics.
