Adafruit I2C Non-Volatile FRAM Breakout - 256Kbit / 32KByte
2022年11月18日 · This particular FRAM chip has 256 Kbits (32 KBytes) of storage, interfaces using I2C, and can run at up to 1MHz I2C rates. Each byte can be read and written instantaneously (like SRAM) but will keep the memory for 95 years at room temperature.

2014年5月20日 · You can create the FRAM object with Adafruit_FRAM_I2C fram = Adafruit_FRAM_I2C(); Then when you begin (), pass in the i2c address. The default is 0x50 so if you don't put any value in the default is used. If you have different addresses, call something like fram.begin(0x53) for example. Then to write a value, call fram.write8(address, byte-value);
Basics of the I2C Communication Protocol - Circuit Basics
2016年2月13日 · With I2C, data is transferred in messages. Messages are broken up into frames of data. Each message has an address frame that contains the binary address of the slave, and one or more data frames that contain the data being transmitted. The message also includes start and stop conditions, read/write bits, and ACK/NACK bits between each data frame:
I2C Communication Protocol - GeeksforGeeks
2024年10月17日 · I2C stands for Inter-Integrated Circuit. It is a bus interface connection protocol incorporated into devices for serial communication. It was originally designed by Philips Semiconductor in 1982. Recently, it is a widely used protocol for short-distance communication. It is also known as Two Wired Interface(TWI). Working of I2C Communication ...

Arduino library for I2C FRAM - Fujitsu MB85RC & Cypress FM24, CY15B I2C Ferroelectric Random Access Memory (FRAM). Read/write endurance for each memory slot : 10^12 cycles and more. 9~16 bit adresses, 8 bits data slots.
RobTillaart/FRAM_I2C: Arduino library for I2C FRAM - GitHub
FRAM is a library to read from and write to (over I2C) an FRAM module. Since 0.5.0 the library provides four classes: FRAM for 16 bit address devices. FRAM32 for 32 (17) bit address devices. FRAM11 for 11 bit address devices. FRAM9 for 9 bit address devices. Currently only the MB85RC1MT is known to use 32 bit.
2024年6月3日 · The I2C FRAM has a default I2C address of 0x50 but you can set the address to any of 8 values between 0x50 and 0x57 so you can have up to 8 of these chips all sharing the same SCL/SDA pins.
