Microchip Technology's AT28HC64B-70JI High-Speed Parallel EEPROM

The AT28HC64B-70JI is a high-performance, 64-Kilobit Parallel EEPROM designed and manufactured by Microchip Technology. This non-volatile memory chip offers a fast access time of 70 nanoseconds, making it an excellent choice for applications that require quick data retrieval without the need for a constant power supply to retain the stored information.

Constructed with advanced CMOS technology, the AT28HC64B-70JI provides a reliable and efficient storage solution. It is organized as 8,192 words by 8 bits, allowing for a substantial amount of data storage while maintaining a compact form factor. The device is housed in a robust 32-lead PLCC (Plastic Leaded Chip Carrier) package, ensuring its durability and ease of integration into a wide range of systems.

One of the key features of this EEPROM is its simple and versatile interface. It is designed to support rapid write cycles and includes features such as hardware data protection and a JEDEC-standardized pinout, which makes it compatible with many microprocessors and microcontrollers. The AT28HC64B-70JI also supports a full static operation, meaning no clock or refreshing is required, and it operates across a wide voltage range of 4.5V to 5.5V.

For added convenience, the AT28HC64B-70JI offers two-line control functions: Chip Enable (CE) and Output Enable (OE). These lines provide a hardware-controlled write protection and ensure that data retrieval is both straightforward and efficient. The device supports a write cycle time of 10 milliseconds, including a byte-write and a page-write function, allowing for both single-byte and multi-byte (up to 64 bytes) writes, which enhances its flexibility for different programming scenarios.

This EEPROM is ideal for a multitude of applications, including but not limited to, personal computers, industrial control systems, medical devices, and telecommunications equipment. Its reliability, coupled with Microchip's commitment to quality, ensures that the AT28HC64B-70JI is a sound choice for designers and engineers looking for a memory solution that offers both performance and endurance.

Overall, the AT28HC64B-70JI from Microchip Technology stands out as a high-speed, durable, and versatile EEPROM that meets the demands of modern electronic applications.
