This document describes a 4 megabit (512K x 8) 5-volt CMOS flash memory with features such as single voltage operation, fast read access time, internal program control and timer.
The document describes the Atmel AT49F040, a 4-megabit (512K x 8) nonvolatile CMOS Flash Memory designed for 5-volt-only operation. It features fast read access times of up to 90 ns and supports in-system reprogramming via byte-by-byte programming with a cycle time of approximately 50 microseconds per byte.
