NM24C32UM8 datasheet

Description

The NM24C32UM8 devices are 32,768 bits of CMOS nonvolatile electrically erasable memory. These devices offer the designer different low voltage and low power options, and they conform to all specifications in the Extended IIC 2-wire protocol. Furthermore, they are designed to minimize device pin count and simplify PC board layout requirements.

Functions :

1. I2C Compatible interface
2. 32,768 bits organized as 4,096 x 8
3. Extened 2.7V – 5.5V operating voltage
4. 100 KHZ or 400 KHZ operation

Features

1. The I2C interface allows the smallest I/O pincount of any EEPROM interface
2. 32 byte page write mode to minimize total write time per byte
3. Typical 200µA active current ( Icca )

Description

The SAMSUNG e·MMC 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 v4.5 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 200MHz 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. […]
