Pull-down, pull-up These terms refer to resistors, sometimes internal to the device, which are
Single chip mode
permanently connected to either ground or V
Pulse width modulation. This term is used to describe a technique where the
width of the high and low periods of a waveform is varied, usually to enable
a representation of an analog value.
Quad flat pack package.
Random access memory. Fast read and write, but contents are lost when the
power is removed.
Radio frequency interference.
Read-only memory. This type of memory is programmed during device
manufacture and cannot subsequently be altered.
A standard serial communications protocol.
Successive approximation register.
Serial communications interface.
‘1’ — the logic one state; the opposite of ‘clear’.
An area in the central belt of Scotland, so called because of the
concentration of semiconductor manufacturers and users found there.
In this mode the device functions as a self contained unit, requiring only I/O
devices to complete a system.
Serial peripheral interface.
This mode is intended for factory testing.
Universal asynchronous receiver transmitter.
Voltage controlled oscillator.
A means of connecting outputs together such that the resulting composite
output state is the logical OR of the state of the individual outputs.
Two bytes; 16 bits.
Non-maskable interrupt request. The overline indicates that this has an
active-low signal format.
