Microchip Technology, Inc. Memory AT49F512-90TC

The AT49F512-90TC is a 5-volt-only in-system programmable and erasable Flash Memory device with a capacity of 512K bits, organized as 65,536 words by 8 bits. It features a fast read access time of 90 ns and supports byte-by-byte programming at a rate of 10 µs per byte. The device includes an 8K byte boot block with a lockout feature for data integrity, allowing secure code storage that can be protected from reprogramming. The AT49F512 offers a fast erase cycle time of 10 seconds and is designed for low power dissipation, with an active current of 30 mA and a standby current of 100 µA. It is capable of enduring approximately 10,000 write cycles. The device incorporates hardware data protection mechanisms and supports data polling for end-of-program detection, ensuring reliable operation during programming and erasing processes. Available in multiple package types, including TSOP and VSOP, the AT49F512-90TC is suitable for applications requiring efficient memory management and secure data storage.
