    An example of this microprocessor is a small PC board called the BASIC Stamp, consisting of 2 ICs - an 18-pin PIC 16C56 CPU (with a BASIC interpreter in 512 word ROM (yes, 512)) and 8-pin 256 byte serial EEPROM (also made by Microchip) on an I/O port where user programs (about 80 tokenized lines of BASIC) are stored.

    Ok a Basic interpreter in 512 Bytes is small but.. it has an easter egg too :eek:

    Says 512 words not bytes. But doesn't say what size a word is for that processor. At a guess though looks like a byte.

    " The PIC 16x is an interesting look at an 8 bit design made with slightly newer design techniques than other 8 bit CPUs in this list - around 1978 by General Instruments (the 1650, a successor to the more general 1600). It lost out to more popular CPUs and was later sold to Microchip Technology, which still sells it for small embedded applications. An example... " (the rest is quoted above)

    From that it's almost definately an 8-bit word... given that they're talking about 8-bit cpus in the same breath.

    P.B.

    Not necessarily... when referring to an 8 bit processor, the 8 bits is the instruction word length, but when referring to storage, it's the length of a data word... i.e. how much can be shifted in one cycle or the size of a register.
