Silicon Oscillator with Reset Output
General Description
The MAX7382 silicon oscillator replaces ceramic res-
onators, crystals, and crystal-oscillator modules as the
clock source for microcontrollers in 3V, 3.3V, and 5V
applications. The MAX7382 features a factory-pro-
grammed oscillator and a microprocessor (µP) power-
on-reset (POR) supervisor.
Unlike typical crystal and ceramic-resonator oscillator
circuits, the MAX7382 is resistant to vibration and EMI.
The high-output-drive current and absence of high-
impedance nodes makes the oscillator less susceptible
to dirty or humid operating conditions. With a wide
operating temperature range as standard, the
MAX7382 is a good choice for demanding home appli-
ance and automotive environments.
The MAX7382 is available with factory-programmed fre-
quencies ranging from 10MHz to 32MHz. See Table 2
for standard frequencies and contact the factory for
custom frequencies. Refer to the MAX7376 data sheet
for frequencies less than 10MHz.
The MAX7382 is available in a 5-pin SOT23 package.
The MAX7382 standard operating temperature range is
-40°C to +125°C. See the Applications Information sec-
tion for extended operating temperature range.

Detailed Description
The MAX7382 is a clock generator with integrated reset
for microcontrollers (µCs) and UARTs in 3V, 3.3V, and
5V applications. The MAX7382 is a replacement for
crystal-oscillator modules, crystals, or ceramic res-
onators, and a system reset IC. The clock frequency
and reset threshold voltage are factory trimmed to spe-
cific values. A variety of popular standard frequencies
are available; see Table 2. No external components are
required for setting or adjusting the frequency.
Oscillator
The push-pull clock output drives a load to within
400mV of either supply rail. The clock output remains
stable over the full operating voltage range and does
not generate short output cycles during either power-on
or changing of the frequency. A typical oscillating start-
up is shown in the Typical Operating Characteristics.
