System Monitoring Oscillator with

Watchdog and Power Fail

General Description

Features

The MAX7387/MAX7388 replace ceramic resonators,

crystals, and supervisory functions for microcontrollers

in 3.3V and 5V applications.

♦ Robust Microcontroller Clock and Supervisor in a

Single Package

♦ Integrated Reset, Watchdog, and Power-Fail

The MAX7387/MAX7388 provide a clock source together

with integrated reset, watchdog, and power-fail func-

tions. The watchdog timer is pin programmable and

provides watchdog timeout values in the 16ms to

2048ms range. The power-fail output provides early

warning of power failure. The power-fail threshold on the

MAX7388 is internally set. The MAX7387 also provides

a separate watchdog output that is used as a status

indicator or to control safety-critical system elements.

Functions

♦ Pin-Programmable Watchdog Timeout

♦ +2.7V to +5.5V Operation

♦ Factory-Trimmed Oscillator

♦ Reset Valid Down to 1.1V Supply Voltage

♦ ±1ꢀmꢁ Clock-Output Drive Current

♦ ±±4 Total ꢁccuracy ꢂor -±ꢀ0C to +1250C

♦ ±2.754 Total ꢁccuracy ꢂor ꢀ0C to +ꢃ50C

♦ -±ꢀ0C to +1250C Temperature Range

The MAX7387/MAX7388 clock outputs are factory pro-

grammed to a frequency in the 1MHz to 16MHz range.

Four standard frequencies are available. Other frequen-

cies are available upon request. The maximum operating

supply current is 5.5mA (max) with a clock frequency of

12MHz.

♦ ꢃ- and 1ꢀ-Pin µMꢁX Surꢂace-Mount Packages

♦ 5.5mꢁ Operating Current (12MHz)

Unlike typical crystal and ceramic resonator oscillator

circuits, the MAX7387/MAX7388 are resistant to EMI

and vibration, and operate reliably at high tempera-

tures. The high-output drive current and absence of

high-impedance nodes make the oscillator invulnerable

to dirty or humid operating conditions.

♦ 1MHz to 16MHz Factory Preset Frequency

The MAX7387/MAX7388 are available in 10-pin and 8-pin

µMAX^®packages, respectively. The MAX7387/MAX7388

standard operating temperature range is from -40°C to

+125°C.

Note: “s” is a placeholder for the reset output type. Insert the

symbol found in Table 3 in the place of “s.” “r” is a placeholder

for the power-on reset (POR) voltage. Insert the symbol found in

Table 2 in the place of “r.” “ff” is a placeholder for the nominal

output frequency. Insert the symbol found in Table 4 in the

place of “ff.” For example, MAX7387CMTP describes a device

with 4.38V reset level, open-collector RST output, and a clock

output frequency of 8MHz.
