C# Class Emlid.WindowsIot.Hardware.Components.Mb85rcv.Mb85rcvDevice

Base class for MB85RC#V FRAM (Ferroelectric Random Access Memory) family of chips (hardware devices), connected via I2C.

The MB85RC#V family are FRAM (Ferroelectric Random Access Memory) chips in different configurations, providing more or less words of memory, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells.

Unlike SRAM, the MB85RC#V chips are able to retain data without using a data backup battery.

The read/write endurance of the nonvolatile memory cells used for the MB85RC#V has improved to be at least 10^12 cycles, significantly outperforming other nonvolatile memory products in the number.

The MB85RC#V chips do not need a polling sequence after writing to the memory such as the case of Flash memory or E2PROM.

Public Methods

Method	Description
GetMemoryAddressBytes ( int address ) : byte[]	Gets the I2C command memory address bytes for the specified logical address. Besides being split into bytes, some older/smaller chips separate the MSB into the I2C device address.
ReadByte ( ) : byte	Reads a single byte at the "current address" (next byte after the last operation).
ReadByte ( int address ) : byte	Reads a single byte "randomly" at the specified address.
ReadPage ( int length ) : byte[]	Reads a single byte at the "current address" (next byte after the last operation).
ReadPage ( int address, int length ) : byte[]	Reads a "page" of bytes "sequentially" starting at the specified address.
WriteByte ( int address, byte data ) : void	Writes a single byte at the specified address.
WritePage ( int address, byte data ) : void	Writes a "page" of multiple bytes starting at the specified address.
WritePage ( int address, byte data, int offset, int length ) : void	Writes a "page" of multiple bytes starting at the specified address.
