Microchip Technology, Inc. Memory AT49BV1604AT-90TI

The AT49BV1604AT-90TI is a 16-megabit Flash memory device from Quarktwin Technology Ltd., designed for single voltage read/write operations ranging from 2.65V to 3.3V. It features a fast access time of 90 ns and supports a dual-plane organization, allowing concurrent read operations while programming or erasing. The memory is segmented into 39 sectors for efficient erase operations, with individual write lockout capabilities for enhanced data protection. This device offers a fast word program time of 20 µs and a sector erase time of 300 ms. It includes an erase suspend feature, enabling data reading or programming from other sectors while an erase operation is in progress. The AT49BV1604AT-90TI operates with low power consumption, drawing 30 mA during active use and only 10 µA in standby mode. It is available in a 48-lead TSOP package and supports both top and bottom boot block configurations. The device also includes a VPP pin for accelerated program/erase operations and a RESET input for initialization.
