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.
