Speed-Switching Clock Generator

with Power Fail

General Description

The MAX7391 replaces ceramic resonators, crystals,

and supervisory functions for microcontrollers in 3.3V

and 5V applications.

Features

♦ Robust Microcontroller Clock and Supervisory

Functions in a Single Package

♦ Integrated Reset and Power-Fail Functions

♦ Speed Select

The MAX7391 provides a clock source, reset, and

power-fail functions. The programmable power-fail func-

tion provides early warning of power failure and is con-

♦ +2.7V to +5.5V Operation

figurable to detect either an external voltage or the V

supply to the device.

♦ Factory-Trimmed Oscillator

♦ Reset Valid Down to 1.1V Supply Voltage

♦ ±1ꢀmꢁ Clock-Output Drive Current

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

The clock output can be switched between normal and

half-speed operation. This functionality allows the micro-

controller to operate at reduced power and may be

used to extend the time available to perform house-

keeping tasks, such as writing data to flash during a

power failure. Connecting the power-fail output to the

SPEED input reduces clock speed automatically during

power-fail events.

♦ ±2.754 Total ꢁccurac ꢂor ꢀ0C to +ꢃ50C

♦ 5.5mꢁ Operating Current (12MHz Version)

♦ -±ꢀ0C to +1250C Temperature Range

♦ Surꢂace-Mount Package

The MAX7391 clock output is factory programmed to a

frequency in the 1MHz to 16MHz range. Four standard

frequencies are available. Other frequencies are avail-

able upon request. The maximum operating supply cur-

rent is 5.5mA (typ) with a clock frequency of 12MHz.

♦ 1MHz to 16MHz Factory Preset Frequency Range

Unlike typical crystal and ceramic resonator oscillator

circuits, the MAX7391 is resistant to EMI and vibration,

and operates reliably at high temperatures. The high-

output drive current and absence of high-impedance

nodes make the oscillator invulnerable to dirty or humid

operating conditions.

U8-1

The MAX7391 is available in an 8-pin µMAX^®package.

The MAX7391 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 2 in the place of “s.” “r” is a placeholder

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

Table 1 in the place of “r.” “ff” is a placeholder for the nominal

output frequency. Insert the symbol found in Table 3 in the

place of “ff.” For example, MAX7391CMTP describes a device

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

output frequency of 8MHz.
