The MSM6150 device also interfaces directly with the first in QCTs powerOne series power management ICs, the PM6650 device. The PM6650 solution provides battery management and charging functions, including a USB charging option, and voltage regulation for the various MSM power regimes, the radioOne Chipset and all other MSM supported peripheral features.
Exceptional power savings are realized through the use of a switch-mode power supply (SMPS) from the PM6650 device to regulate the MSM core voltage. All voltages generated for the MSM and radioOne RF Chips are optimized for handset system control with the MSM6150 system software.
The C505L enhances the C500 family of 8-bit Microcontrollers by a new member which provides on-Chip LCD. The device provides 32 KByte of OTP, 512 Bytes of RAM, LCD, an asynchronous/synchronous serial interface and a highly accurate 10-bit ADC with a 6 µs conversion time integrated on-Chip. Typical applications for the C505L are electricity meters, utility meters, intelligent terminals and controllers. This device has several power saving modes, including one in which the on-Chip RTC is functioning with a typical power consumption of 50 µA at 3 V.
DESCRIPTION The CMOS device iC-MA consists of a quadruple Hall sensor array which has been optimized for the magnetic measurement of angles of rotation. This array permits error-tolerant adjustment of the magnet, reducing assembly efforts. The integrated signal conditioning unit provides a differential sine/cosine signal at the output. The sensor generates one sine cycle per each full rotation of the magnet, enabling the angle to be clearly determined. At the same time the internal amplitude control unit produces an regulated output amplitude of 2 Vpp regardless of variations in the magnetic field strength, supply voltage and temperature. Furthermore, signals are provided which enable the sensor amplitude to be assessed and also report any magnet loss.
FEATURES ♦ Quadruple Hall sensor array for error-tolerant adjustment ♦ Non-sensitive to magnetic stray fields due to differential measurement technique ♦ Interpolator with a resolution of up to 256 angle steps per cycle ♦ Rotational speeds up to 60 000 rpm ♦ 4 buffered I/O stages for signal outputs ♦ Three configuration inputs for operating mode selection ♦ Analog operation modes: - sine/cosine signals controlled to 2 Vpp - triangle or sawtooth signal with selectable amplitude ♦ Digital operation modes: - A/B quadrature signals with Z index pulse - Counter pulses for external binary counters ♦ Cascading of multiple iC-MA possible for chain operation ♦ Error signal output for detection of low magnetic field strength ♦ Additional operating modes with reduced power consumption ♦ Standby mode when not enabled ♦ Extended temperature range of -40...+125 °C
