SH3100

Supervisory IC with I²C

Interface and PWM

POWER MANAGEMENT

Description

The SH3100 is a size, power, and cost-saving solution for microprocessor support functions. It is intended to replace

a number of peripheral devices normally used in conjunction with a microprocessor. Its prime function is to provide

an accurate and stable clock source which can be started up and shut down very quickly to enable it to be used in a

pulsed fashion for very low power applications.

The SH3100 consumes very little power when in standby, and it provides a stable output clock in less than 2μs. This

allows it to outperform ceramic resonators and crystals requiring much longer start-up times.

Features

ꢀMaster HFDCO oscillator which can be programmed to ꢀPeriodic interrupt timer (PIT) with a 30μs resolution

between 8MHz and 33.5MHz with 2kHz resolution

up to 36 hours

ꢀA 32.768kHz crystal oscillator with 5-bit programma-

ble padding capacitance giving a frequency adjust-

ment resolution of 4ppm

ꢀReal time clock with 1/256 second resolution up to

Year 2099

ꢀSpread spectrum option on the output clock

ꢀTwo clock outputs, each of which can be powered inde

pendently from VDD or VBAK and can operate either

in-phase or in complementary mode

ꢀBattery backup facility, which maintains register con-

tents less than 2μA consumption

ꢀAn internal oscillator which is fuse-calibrated to

provide a 32.768kHz clock source, accuracy is better

than ±3% over temperature and supply voltage

ꢀ1.7V to 5.5V operating range on the main VDD supply

ꢀ0.9V to 5.5V operating range on the battery backup

supply (VBAK)

ꢀ96-bit electrically programmable non-volatile fuse

memory array

ꢀEdge-triggered, level-sensitive, and toggling interrupt

output (INT)

ꢀ7-bit programmable threshold reset comparator (VBO)

between 1.7V and 4V with 24mV resolution

ꢀGeneral-purpose I/O option on the interrupt pin (INT)

ꢀProgrammable reset duration between 6ms and 5.3

ꢀLow power, low dropout voltage regulator (LDO) output

seconds

on PWM pin

ꢀLess than 10μA standby current and less than 12mA

ꢀSwitched mode boost, bootstrap boost, and buck

maximum operating current (excluding LDO load)

regulation control

ꢀI²C interface with 3-bit fuse-settable address complies

with I²C fast mode speciﬁcation

ꢀ56 bytes of control registers including a 9-byte

scratchpad

ꢀGeneral-purpose 8-bit DAC and Comparator

ꢀGeneral-purpose PWM & PDM output

ꢀSmall 3mm x 3mm 16-lead MLP package

Covered by United States Patent 6,903,986
