Microchip Technology, Inc. Memory AT29C010A-90PI

The AT29C010A-90PI is a 5-volt-only Flash programmable and erasable read-only memory (PEROM) with a capacity of 1 megabit, organized as 131,072 words by 8 bits. It features a fast read access time of 90 ns and supports sector programming with a cycle time of 10 ms. The device includes 1024 sectors, each containing 128 bytes, and offers internal address and data latches for efficient operation. This memory chip is designed for in-system reprogrammability, requiring only 5-volt commands for programming. It has a typical endurance of over 10,000 write cycles and operates with low power dissipation, consuming 50 mA during active operation and 100 µA in CMOS standby mode. The AT29C010A also incorporates hardware and software data protection features to prevent inadvertent programming. The device is compatible with both CMOS and TTL logic levels and is available in various package types, including a 32-lead PDIP. It operates over commercial and industrial temperature ranges, making it suitable for a variety of applications.
