Product Description
Microchip AT28HC64B-70JU is a high-performance 64 kB parallel EEPROM designed for reliable memory storage in electronic circuits. Featuring a fast 70 ns access time, this device supports a parallel interface and is packaged in a 32-pin PLCC surface mount package, making it suitable for compact and high-density PCB layouts.
The memory is organized as 8 Kbits x 8 bits, offering a total of 8192 words, with a supply voltage tolerance of 4.5 to 5.5 volts. Operating efficiently across a temperature range from -40°C to 85°C, this EEPROM fits demanding industrial and commercial applications.
With a low supply current of 40mA during operation and CMOS standby current under 100μA when deselected, the AT28HC64B-70JU ensures power-efficient performance. Its self-timed erase and write cycles conclude within 10 milliseconds, enhancing data write reliability and speed.
The device includes a 64-byte page register allowing simultaneous writing of up to 64 bytes, optimizing performance in batch data writes. It also incorporates optional software data protection to guard against inadvertent writes. Data retention is guaranteed for up to 10 years, supporting long-term data integrity.
This EEPROM is ideal for use in industrial automation, consumer electronics, and embedded systems requiring non-volatile memory. Its parallel interface and 32-pin PLCC package facilitate easy integration into existing PCB designs.
