Description: The Artship Technology Inc. 24LC16B (24XX16*) is a Kbit Electrically Erasable PROM. The device is organized as eight blocks of X 8- bit. serial interface. Low voltage design permits operation down to volts with standby and active currents of only 5 µA and 1 mA respectively.

Microchip – datasheet pdf
I did not use the 24LC16 so far but “smaller” devices, like the 24LC Where none of the 24lx16b equivalents do address decoding at all. Nate, I was just curious, and got the ST datasheet for their 24C Let’s say I have an sx set up as a slave on that same bus, and i would like to send some info to only the sx, I could set the address to some abritrary number, but the eeprom would answer to any address, correct?
I realise that i could probably set the write protect pin of the eeprom, but i would rather just get a different chip. John, fortunately, this is not the case. Comments 9 Comments sorted by Date Added Votes.
Addressing of the devices is performed by sending a control byte via the bus. In these datasheets they also state that the address pins are not connected.
In this system, each of the SXes could act as master and slave, therefore I also had to handle bus arbitration but it worked nicely in the end. So it would be getting all of datashet bytes sent to it also.
On 24,c16b other hand, on page 6 where the control byte is explained, they say that the three bits in the control byte are used to select one of the eight word blocks of the memory. Thanks for your help! I use the 24LC64 in some of my SX applications with no problems.
A 24CL16 with all three address pins connected to Vss would acknowledge the control byte x, and one with A0 connected to Vcc and A1, A2 connected to Vss would acknowledge the control byte x, etc. Sign In or Register to comment. This doesn’t mean that you couldn’t use more than 1 chip, simply that you cannot use the multiple IC2 address protocall.

Nate, this is strange. A while ago, I have developed a system similar to this with up to 5 SXes on one bus. Hey, you can find the datasheet for the 24LC16 here: As the address following the control byte is only 8 bits wide, three additional bits are required to cover the full address space of bytes.

They definitely allow for eight devices on a bus, and they have two address bytes following the control byte in order to address the full range of the memory. I am looking to have possible 4 sx’s set up as slaves, and 1 eeprom and one rtc all set up on the same i2c bus if thats possible.
24LC16B Technical Data
So that means, 24lc16g only is it limited to only one of those devices, but only one of any device, right? Maybe, this explains the difference. In the end, this solution my be even cheaper as one 24LC64 replaces four 24LC16 chips, and there is no need for some “tricky” decoding. Gunther, Page 11 of said datasheet states that A0, A1, and A2 are not connected in this device.
But I could successfully verify that the chips decode the status of the address pins.
Perhaps you consider using 24LC64 chips instead. Their 01 and datasgeet devices actually have the three address bits decoded, the 04 device has two bits decoded, the 08 device just one, and the 16 device none at all.
Seems as if there actually can only be one 24LC16 on a bus without additional decoding. Nate Post Edited Nate:
