AT17LV020A-10JI application field and working principle

AT17LV020A-10JI is a low-power non-volatile configurable memory device, which is mainly used for configuration prom of field programmable gate array (FPGA). This device is based on 0.4 micron CMOS logic process technology. It can assist the user to store the configuration information of FPGA quickly and correct. It is mainly used in system board design, high speed communication and real-time control system.

AT17LV020A-10JI is a 2K x 8 x 8 configuration PROM, which has a 256-byte page size. It has a three-state output structure and allows data that can be inverted with respect to the power source. This device can also be operated at a fast programming speed up to 500kHz. It offers 5V, 3V and 2.5V operating voltage power supply options, and features access times of 45ns for 5V and 3V, and 55ns for 2.5V. The device also provides Vcc under voltage detection and automatic switching, which can prevent data from loss during over-voltage short circuit or power off.

The working principle of AT17LV020A-10JI involves the use of a combination of a laser programmable antifuse, an EPROM window, and HI/LO byte and byte/disable electrical programming. After configuring the FPGA, an information signal will be generated, and then it will be sent to the AT17LV020A-10JI. The laser programmable antifuse in the device will receive the signal, and then it will be programmed accordingly. The signal will then be written in the EPROM window, the HI/LO byte and byte/disable electrical programming will be used to program the desired data. The combination of these processes will program the device and read back the desired data.

In conclusion, AT17LV020A-10JI is primarily used in the field of FPGA configuration memory. By using a combination of laser programmable antifuse, EPROM window, HI/LO byte and byte/disable electrical programming, the device can effectively store configuration information from FPGA and read back the data quickly and accurately. This device is suitable for use in system board design, high speed communication and real-time control system.
