Low-Voltage Detect
Encyclopedia
A Low-Voltage Detect is a microcontroller
or microprocessor
peripheral
that generates a reset
signal when Vcc falls below Vref. Sometimes is combined with Power-on reset
(POR) and then it is called POR-LVD.
Microcontroller
A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM...

Peripheral
A peripheral is a device attached to a host computer, but not part of it, and is more or less dependent on the host. It expands the host's capabilities, but does not form part of the core computer architecture....
