Microchip Technology, Inc. Memory AT49F001T-70VC

The AT49F001T-70VC is a 1-megabit (128K x 8) Flash memory device that operates at a single voltage of 5V for both read 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 with programming lockout, 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 is designed for in-system reprogrammability without requiring high input voltages. It includes hardware data protection and a DATA polling feature for end-of-program detection. The AT49F001T-70VC has a low power dissipation profile, with an active current of 50 mA and a CMOS standby current of 100 ¬µA. It is rated for a typical endurance of 10,000 write cycles. The device is available in a 32-lead VSOP package and is suitable for commercial applications with an operating temperature range of 0¬8 to 70¬8C. The boot block protection feature ensures data integrity by preventing reprogramming of the boot sector once enabled.
