I have a project in mind using small Flash RAM and a cheap CPU to substitute for the old TTL level CMOS RAM used on arcade games. This has come up because the NVRAM that is currently being used is getting hard to find at prices under $7 to $9USD. Something like the M25P05-AVMN6P (512k or 64K x 8) or similar chips are $0.20 in single quantities. The size of CMOS RAM we are replacing ...

Hi all, I'm looking for a small-real-estate solution to generate a clock (ttl/cmos 5V) from a given quartz oscillator. The output clock I need is 4/9 or 4/7 ratio of the original input clock. I know I can easily make a VCO/PLL solution, but the real problem is a very small space on the PCB, so I might be able to use a couple of small ICs, but probably not too much else. Input clock is < 2
