AT29C040A-12TI General Description

The AT29C040A-12TI is a 4-megabit (4Mb) parallel flash memory chip manufactured by Atmel, now part of Microchip Technology. It operates with a supply voltage of 5 volts (V), and the "12" in its designation indicates its access time, which is 120 nanoseconds (ns). This means it takes 120 ns to access data stored in the memory. The "TI" likely refers to the package type, which could be a Thin Small Outline Package (TSOP) or similar. This flash memory chip is commonly used in embedded systems, consumer electronics, and other applications where non-volatile storage is required. It offers reliable data retention and endurance characteristics, making it suitable for various industrial and commercial applications. The parallel interface allows for fast data transfers between the memory and the microcontroller or other devices. Additionally, it typically features sector erase and byte programming capabilities, enabling flexible and efficient memory management.
