Replacement?

Hi,

I'd really like to use this part/library but it appears that the SAA1064 and all variations of it from NXP have reached End Of Life. Does anybody know of any similar parts that could replace it? I contacted NXP and they do not have any replacements being made, but I was wondering if any other IC company was making something similar.

Thanks!

Of course different to your NXP SAA1064 but Adafruit make a range of 7-segment LED display modules like the one here https://www.adafruit.com/product/878 that use the Holtek HT16K33 I2C 16x8 LED driver with keyboard scanning https://cdn-shop.adafruit.com/datasheets/ht16K33v110.pdf. There's plenty of example code on mbed like this https://os.mbed.com/users/onehorse/code/BMP180/file/06dc60296e6e/HT16K33.h/ I've used the HT16K33 successfully with mbed and they work well.

If you check ebay there are still plenty of them around. http://www.ebay.nl/sch/i.html?_odkw=SAA1064&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313&_nkw=SAA1064&_sacat=0

There are also other I2C LED drivers available from NXP. Maxim have LED/7 segment drivers also, but they are not hardware compatible.

Also checkout the new LED driver components PT6961, PT6964 and TM1638. They have SPI interfaces, but offer more digits and keyboard scanning.
