ADC = Analog to Digital Converter
CPU = Central Processor Unit
CISC = Complex Instruction Set Computing, processors with large instruction set, e.g. more than 100
DAC = Digital to Analog Converter
EEPROM = Electrically Erasable Read Only Memory, a read cycle is just as fast as ram, but write or erase is slower.
EPROM = Erasable Programmable Read Only Memory, erased by UV light thru a window
FPU = Floting Point Unit, processor for fast math.
GAL = Gate Array Logic . ???
ICE = In Curcuit Emulator, a hardware CPU emulator/debuger.
IC = Integrated Curcuit, or micro-chip
MPU = Master Processor Unit
MUX = Multi plexer, a digital or analog switch.
OTP = One Time Programmable, mostly normal EPROM types without the window.
PAL = Programmable gate-Array Logic ???
PEEL = Programmable Electrically Erasable Logic ???
PPI = Programmable Peripheral Interface, almost all port IC's are PPI
PIO = Parallel Input Output
RISC = Reduced Instruction Set Computing, processors with small instruction set, e.g. from 30 to 80
RAM = Random Access Memory, read & write memory.
ROM = Read Only Memory.
SIO = Serial Input Output, see UART
UART = Universal Asynchronous Receiver Transmitter, the serial port IC
SERIAL = one signal line, transfering meny bits,
PARALLEL = each I/O-line reprecent a digital bit and can be set high or low.
TRISTATE = an Output line with the capability to be disabled and then goes in a hight impedance state.
