I2c eeprom memory

Description: The AT24C01A/02SC/04SC/08SC/16SC provide bits of serial, electrically-erasable, and programmable read-only memory (EEPROM) organized as words of 8 bits each. The devices are optimized for use in smart card applications where low-power and low-voltage operation may be essential. The devices are available in several standard ISO smart card modules (see Ordering Information, pages ). All devices are functionally equivalent to Atmel serial EEPROM products offered in standard IC packages (PDIP, SOIC, TSSOP, MAP), with the exception of the slave address and write protect functions, which are not required for smart card applications. Features: Chip: AT24C02 Size: 1.9 x1.1 (CM) Storage tool for EEPROM with I2C interface Main resource: AT24CXX,12C pin header" Box Pack - No Warranty

Features and Details DS1307 is a real-time chip of DALLAS company,which adopt I2C protocol to communicate with SCM, and there was this kind interface on Arduino, therefore is very convenient to link with each other. DS1307 have a programmable waveforms output, it can be used to drive LED lights, or trigger a certain event as a break off, but be careful when you use it to take some kind of high power module. We design the real clock module to pin out the I2C interface of Ds1307 and programmable waveforms output interface SQW are connected, but usually we will only use the I2C interface to realize basic set the clockread function. Note, this module must be installed on the battery can work normally. The battery is button batteries type CR2032 will be better Feature 1- Power supply 5V DC and Button Battery 2- Interface IIC 3- Size 16mm 22mm 23mm Almost same size as CR2032 Button Battery 4- Memory Capacity 32K bit
