PRODUCT DESCRIPTION
The AT49F1025-70JI is a Flash memory Integrated Circuit (IC) manufactured by Microchip Technology. It is a non-volatile memory device that can be electrically programmed and erased. Here are some key features of the AT49F1025-70JI:
1. Memory Capacity: The IC has a total memory capacity of 1 Megabit (1 Mb) or 128 kilobytes (128 KB). It is organized into 128 sectors, each consisting of 64 bytes.
2. Operating Voltage: The AT49F1025-70JI operates at a voltage range of 4.5V to 5.5V. It requires a single power supply for both read and write operations.
3. Access Time: The access time of this Flash memory IC is 70 nanoseconds (ns). This refers to the time it takes for the device to access a specific memory location.
4. Interface: It uses a standard parallel interface for communication with the external microcontroller or system. The interface consists of address lines, data lines, control signals (such as chip enable, output enable, and write enable), and other control inputs.
5. Erase and Program Operations: The AT49F1025-70JI supports both sector erase and byte programming operations. The sector erase operation allows for erasing a full sector (64 bytes) at a time, while byte programming allows for programming individual bytes.
6. Endurance and Retention: The IC has a typical endurance of 10,000 erase/write cycles per sector. It also has a typical data retention period of 20 years.
7. Package: The AT49F1025-70JI is available in a 32-pin plastic J-lead (PLCC) package. This package type provides good thermal and electrical characteristics.
The AT49F1025-70JI Flash memory IC is commonly used in various applications, including embedded systems, automotive electronics, consumer electronics, and industrial control systems.
