Microchip Technology, Inc. Memory AT49F001-70JI

The AT49F001-70JI is a 1-megabit (128K x 8) Flash memory device that operates at a single voltage of 5V for both reading and reprogramming. It features a fast read access time of 70 ns and a typical byte programming time of 10 µs. The memory is organized into a sector architecture that includes one 16K byte boot block, two 8K byte parameter blocks, and two main memory blocks of 32K and 64K bytes. This device supports a fast erase cycle time of 10 seconds and offers hardware data protection along with DATA polling for end-of-program detection. It has a low active current of 50 mA and a standby current of 100 µA, making it suitable for low power applications. The AT49F001-70JI is designed for in-system reprogrammability, requiring only 5V commands for operations, and can endure a typical 10,000 write cycles. The boot block includes a programming lockout feature to protect critical data, ensuring that once enabled, the contents cannot be altered. The device is available in a 32-lead PLCC package, making it compatible with various applications requiring reliable non-volatile memory solutions.
