The AM28F512A-200JC is a 512 Kbit (64K x 8) CMOS Flash memory manufactured by Advanced Micro Devices (AMD). It provides non-volatile storage that can be electrically erased and reprogrammed, making it suitable for applications that require frequent updates or storage of configuration data. The '200' in the part number indicates an access time of 200 nanoseconds.
Applications:
- Embedded Systems: Storing firmware and boot code in embedded microcontrollers and processors.
- Industrial Control Systems: Configuration data and operating parameters for programmable logic controllers (PLCs).
- Telecommunications Equipment: Storing system settings and boot code in communication devices.
- Instrumentation: Storing calibration data and program code for test and measurement instruments.
- Automotive Systems: Used in automotive electronics for storing ECU (Engine Control Unit) firmware.
Features:
- 512 Kbit (64K x 8) Memory Organization: Provides a storage capacity of 524,288 bits organized as 65,536 bytes of 8 bits each.
- Access Time: 200 ns access time allows for relatively quick data retrieval.
- Electrically Erasable and Programmable: Enables in-system programming and updates without removing the device.
