function, manufactured using laser trimming
technology.
The series consist of a reference voltage source,
delay circuit, comparator, and output driver. With the
built-in delay circuit, the series do not require any
external components.
The
RESET
output is active LOW, when voltage below
V
DFL
is detected.
The EN (EN pin controls ON/OFF state of the
watchdog functions. This pin in an active state
disables the watchdog function, while the voltage
detector remains operational.
The IXD5122 and IXD5124 series have internal pull-
up/down resistors respectively that allows use these
IC with watchdog function active, while EN (EN pins
are left open.
The detect voltages are internally fixed in the range
from 1.6 V to 5.0 V in 0.1 V increments.
Six watchdog timeout periods are available in a range
from 50 ms to 1.6 s.
Five release delay times are available in a range from
3.13 ms to 400 ms.
With low power consumption and high accuracy, the
series is suitable for precision mobile equipment.
The IXD5121/22/23/24 in ultra small packages are
ideally suited for high-density PC boards.
The IXD5121/22/23/24 is available in N-channel open
drain output configuration only.
Detector is available in USP-6C and SOT-25
packages.

The difference between 89c52 and 89s52 microcontrollers
A search on Baidu yielded the following answer: There is a little difference, but not a big one: 1. The former does not support in-system programming, while the latter does. 2. The 89C52 has one data ...
