The AT49F1024A is a 5-volt-only in-system Flash memory organized as 65,536 words by 16 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 45 ns with power dissipation of just 275 mW over the commercial temperature range. It features single-voltage operation, fast erase cycle time, hardware data protection, and is suitable for simple in-system reprogrammability.
The AT49F1024A is a 5‑volt‑only, 1‑Megabit (64K × 16) in‑system flash memory offered in a 10 × 14 mm VSOP package. It features fast 45 ns read access, 10 µs word programming, and typical endurance of over 10,000 write cycles.
The device includes an optional 8 K‑word boot block with a programmable lockout feature, data‑polling and toggle‑bit status signals, and a full set of timing and electrical specifications for reliable operation across a wide temperature range.
