Description

The KLM8G2FE3B-B001 is an embedded MMC solution designed in a BGA package form. e·MMC operation is identical to a MMC card and therefore is a simple read and write to memory using MMC protocol v4.41 which is a industry standard.

e·MMC consists of NAND flash and a MMC controller. 3V supply voltage is required for the NAND area (VDDF) whereas 1.8V or 3V dual supply voltage (VDD) is supported for the MMC controller. Maximum MMC interface frequency of 52MHz and maximum bus widths of 8 bit are supported.

There are several advantages of using e·MMC. It is easy to use as the MMC interface allows easy integration with any microprocessor with MMC host. Any revision or amendment of NAND is invisible to the host as the embedded MMC controller insulates NAND technology from the host. This leads to
faster product development as well as faster times to market.

The embedded flash mangement software or FTL(Flash Transition Layer) of e·MMC manages Wear Leveling, Bad Block Management and ECC. The FTL supports all features of the Samsung NAND flash and achieves optimal performance.

What is EEPROM?

EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is a non-volatile memory technology that allows for both reading and writing of data. EEPROM retains the stored data even when power is removed, making it suitable for applications that require persistent storage.

Unlike traditional ROM (Read-Only Memory), which is programmed during manufacturing and cannot be modified, EEPROM provides the capability to erase and reprogram individual memory locations electrically. This makes it more flexible and allows for data updates or modifications in the field.

Description for 24C64WP

These I2C-compatible electrically erasable programmable memory (EEPROM) devices are organized as 8192 x 8 bits (M24C64) and 4096 x 8 bits (M24C32). I2C uses a two-wire serial interface, comprising a bi-directional data line and a clock line. The devices carry a built-in 4-bit Device Type Identifier code (1010) in accordance with the I2C bus definition. The device behaves as a slave in the I2C protocol, with all memory operations synchronized by the serial clock. Read and Write operations are initiated by a Start condition, generated by the bus master.
