Two tubes of 23LC1024 SRAMs from Microchip
Microchip sent two tubes of mislabeled 23lc1024 SRAM chips to play with. First project is Logic Shrimp v2.
EEPROM with single pin interface
Two years ago Microchip introduced serial EEPROMs with UNI/O. The speciality is the single pin data interface, so the memory chip needs only 3 pins including power. This can be great help for the smallest 6-pin microcontrollers like PIC10F or ATtiny10 series which doesn’t have any non-volatile memory writable from application itself. Memory densities range […]
Adding RAM to Atmega128
If you want more memory on an Atmega128 project, Scienceprog has a project for expanding the 4 kb internal memory up to 64kb using a 74HC573 to interface a standard memory chip. Via Hack a Day
