Description
The M41T00AUD is a low power serial real-time clock (RTC) with an integral audio section with tone generator and 300mW output amplifier.
Features
■ Combination real-time clock with audio
– Serial RTC based on M41T00
– Audio section provides:
– 300mW differential audio amplifier
– 256 and 512Hz tone generation
– -33 to +12dB gain, 3dB steps (16 steps
plus MUTE)
■ Real-time clock details:
– Superset of M41T00
– 3.0 to 3.6V operation
– Timekeeping down to 1.7V
– Automatic backup switchover circuit
– Ultra low 400nA backup current at 3.0V
(typ)
– Suitable for battery or capacitor backup
– On-chip trickle charge circuit for backup
capacitor
– 400kHz I2C bus
– M41T00 compatible register set with
counters for seconds, minutes, hours, day,
date, month, years, and century
– Automatic leap year compensation
– HT bit set when clock goes into backup
mode
– RTC operates using 32,768Hz quartz
crystal
– Calibration register provides for
adjustments of -63 to +126ppm
– Oscillator supports crystals with up to
40kΩ series resistance, 12.5pF load
capacitance
– Oscillator fail detect circuit OF bit indicates
when oscillator has stopped for four or
more cycles
■ Audio section
– Power amplifier
– Differential output amplifier
– Provides 300mW into 8Ω (THD+N = 2%
(max), fin = 1kHz)
