Microchip Technology, Inc. Memory - AT49BV163AT-70TI AT49BV163AT-70TI

The AT49BV163AT-70TI is a 16-megabit Flash memory device from Quarktwin Technology Ltd., organized as 1,048,576 words of 16 bits each or 2,097,152 bytes of 8 bits each. It operates on a single voltage range of 2.65V to 3.6V and features a fast read access time of 70 ns. The memory is structured with 39 sectors for erase operations, including thirty-one 32K word sectors and eight 4K word sectors, each with individual write lockout capabilities. This device supports a fast word program time of 12 µs and a sector erase time of 300 ms. It includes a suspend/resume feature that allows reading and programming from any sector while suspending erase or programming operations in others. The AT49BV163AT-70TI is designed for low-power operation, consuming 12 mA in active mode and only 13 µA in standby mode. It also features data polling, toggle bit, and a READY/BUSY output for end-of-program detection. The device is available in a 48-lead TSOP package and supports a top or bottom boot block configuration. It has a minimum endurance of 100,000 erase cycles and includes a 128-bit protection register. The VPP pin provides write protection, and the RESET input is available for device initialization. The AT49BV163AT-70TI is suitable for applications requiring reliable in-system programming and data protection.
