AT29C512-70PC 512KBIT CMOS FLASH EEPROM IC PDIP-32

AT29C512-70PC 512KBIT CMOS FLASH EEPROM IC PDIP-32

The AT29C512-70PC is a 5V-only in-system Flash programmable and erasable read-only memory (PEROM) manufactured using Atmel’s advanced nonvolatile CMOS technology. It offers a dense storage capacity of 512 kilobits, organized as 65,536 words by 8 bits, making it suitable for embedded systems where firmware or data must be updated without removing the chip from the circuit board.

This device supports sector-based reprogramming, where 128-byte sectors can be erased and programmed in a single cycle, greatly simplifying the update process. Internal address and data latches hold an entire sector during programming, freeing the external bus for other operations. The chip incorporates both hardware and software data protection mechanisms to prevent accidental writes, enhancing data integrity in noisy or unstable environments.

Designed for efficient operation, the AT29C512-70PC provides fast read access times of 70 ns and consumes low power, with a typical active current of 50 mA and a CMOS standby current of only 100 µA. It features built-in timers and polling functions to manage programming cycles autonomously, ensuring reliable performance across commercial temperature ranges without requiring complex external circuitry.
