Although real-world signals will always be analog, today more and more analog ICs communicate through digital interfaces. Serial interfaces communicate between a master, which provides the serial clock, and a slave/peripheral. Today's SPI (3-wire) and I2C (2-wire) ports found on most microcontrollers
are popular means for transmitting and receiving data. Microcontrollers thus communicate over several bus lines to control peripherals including analog-to-digital converters (ADCs), digital-to-analog converters (DACs), smart batteries, port expanders, EEPROMs, and temperature sensors. Unlike data sent through a parallel interface, serial data is transmitted with numerous bits in succession, usually over two, three, or four data/timing lines. Although parallel interfaces offer speed, serial interfaces have the advantage of much fewer control and data lines.
Power Management
IC
The RS2586/RS2587 power-management ICs are optimized for devices using Intel X-Scale? microprocessors, including third-generation smart cell phones, PDAs, internet appliances, and other portable devices requiring substantial computing and multimedia capability at low power.
The ICs integrate seven high-performance, low-operating-current power supplies along with supervisory and management functions. Regulator outputs include three step-down DC-DC outputs, three linear regulators, and a seventh always-on output. DC-DC converter outputs power I/O, DRAM, and the CPU core. The I/O supply can be preset to 3.3V or 3.0V, or can be adjusted to other values. The DRAM supply on the RS2586A and RS2587A is preset for 1.8V or 2.5V, while the RS2586B DRAM supply is preset for 3.3V or 2.5V. The DRAM supply on all parts can also be adjusted with external resistors. The CPU core supply is serial programmed for dynamic voltage management. Linear-regulated outputs are provided for SRAM, PLL, and USIM supplies.
To minimize sleep-state quiescent current, critical power supplies have bypass "sleep" LDOs that can be activated to minimize battery drain when output current is very low. Other functions include separate on/off control for all DC-DC converters, low-battery and dead-battery detection, a reset and power-OK output, a backup- battery input, and a two-wire serial interface.
All DC-DC outputs use fast, 1MHz PWM switching and small external components. They operate with fixed-frequency PWM control and automatically switch from PWM to skip-mode operation at light loads to reduce operating current and extend battery life. The core output is capable of operating in forced-PWM mode at all loads to minimize ripple and noise. A 2.6V to 5.5V input voltage range allows 1-cell lithium-ion (Li+), 3-cell NiMH, or a regulated 5V input. The RS2587 is available in a tiny 6mm x 6mm, 40-pin thin QFN package. The RS2586 features an additional linear regulator (V6) for VCC_USIM and low-battery and dead- battery comparators. The RS2586 is available in a 7mm x 7mm, 48-pin thin QFN package.
