AT49BV642D-70TU Description

Short technical summary and product information.

The AT49BV642D(T) from Atmel is a 64-megabit Flash memory organized as 4,194,304 words of 16 bits each. It operates from a single 2.7V to 3.6V power supply, making it suitable for in-system programming applications.

Key features include a fast 70 ns access time and a fast word program time of 10 µs. The memory is divided into 135 sectors for erase operations, including 127 main sectors and 8 smaller sectors, each with individual write lockout. It also supports Erase Suspend and Program Suspend features, allowing data to be read or programmed from other sectors during these operations.

This device operates with low power consumption, drawing 10 mA in active mode and 15 µA in standby mode. It utilizes a TSOP package and offers Top or Bottom Boot Block Configuration. The VPP pin provides write protection and accelerated program operations, while the RESET input initializes the device.

Additional features include a 128-bit protection register and Common Flash Interface (CFI) support. The packaging is described as Green (Pb/Halide-free).
