M29F400T70N3R

4M-bit NOR Flash memory with parallel interface, featuring 512K x 8 or 256K x 16 word organization and a maximum access time of 70 ns. This integrated circuit operates from a 4.5 to 5.5 V programming voltage and a typical 5 V supply, with a maximum operating current of 20 mA. The component is housed in a 48-pin RTSOP (Thin Small Outline Package) with gull-wing leads for surface mounting, measuring 12 mm in length and 18.4 mm in width. It supports an asynchronous timing type, has a 19/18 bit address bus, and includes a top-located boot block. Operating across a temperature range of -40 °C to 125 °C, this memory offers asymmetrical block architecture.
