Microchip Technology, Inc. Memory - Flash - AT49F001NT-90JC AT49F001NT-90JC

The AT49F001NT-90JC is a 1-megabit Flash memory device from Quarktwin Technology Ltd., designed for single voltage operation at 5V for both reading and reprogramming. It features a fast read access time of 90 ns and a fast erase cycle time of 10 seconds. The memory is organized into a sector architecture that includes one 16K byte boot block with programming lockout, two 8K byte parameter blocks, and two main memory blocks of 32K and 64K bytes. This device supports byte-by-byte programming with a typical time of 10 ¬µs per byte and offers hardware data protection along with DATA polling for end of program detection. It operates with a low power dissipation of 50 mA during active use and 100 ¬µA in CMOS standby mode, making it suitable for power-sensitive applications. The typical endurance is rated for 10,000 write cycles. The AT49F001NT-90JC is available in a 32-lead PLCC package and is suitable for commercial temperature ranges from 0¬8C to 70¬8C. Its design allows for in-system reprogrammability without the need for high input voltages, making it a flexible choice for various applications.
