General Description
The MAX7376 silicon oscillator with reset, is a replace-
ment for ceramic resonators, crystals, crystal oscillator
modules, and discrete reset circuits. The MAX7376 pro-
vides the primary clock source and reset function for
microcontrollers in 3V, 3.3V, and 5V applications. The
MAX7376 features a factory-programmed high-speed
oscillator and a microprocessor (μP) power-on-reset
(POR) supervisor.
Unlike typical crystal and ceramic resonator oscillator
circuits, the MAX7376 is resistant to vibration and EMI.
The high-output-drive current and absence of high-
impedance nodes make the oscillator less susceptible
to dirty or humid operating conditions. With a wide
operating temperature range as standard, the MAX7376
is a good choice for demanding home appliance,
industrial, and automotive environments.
The MAX7376 is available in factory-programmed fre-
quencies from 32.768kHz to 10MHz. See Table 2 for
standard frequencies and contact the factory for cus-
tom frequencies.
The MAX7376 is available in a 5-pin SOT23 package.
Refer to the MAX7382 data sheet for frequencies
≥
10MHz. The MAX7376 standard operating tempera-
ture range is -40
°
C to +125
°
C. See the
Applications

section for the extended operating temper-
ature range.
