Motorola is developing a family of microcontrollers for the driver information systems (DIS) market.
MCU and DSP features combine in Flash hybrids
The 56F826 and 56F827 are Motorola's newest Flash-based hybrid controllers.
"The name of the game in portable consumer devices today is battery life, battery life and more battery life", said Stephanie Guza, Analyst for In-Stat.
"Low-voltage designs enable longer battery life and are critical for semiconductor manufacturers that compete in this space".
The MPC18730 minimises power consumption by using two DC/DC convertors to generate the main supply voltages and three series regulators for the auxiliary rails.
All five supplies are digitally controlled with digital-to-analogue convertors (DACs), through a serial interface.
The serial interface also controls multiple power save modes, such as sleep, wake-up and on/off, making the MPC18730 ideal for long-life portable electronics.
The MPC18730 operates from either a single cell Li-ion (2.7 to 4.2V input range) or a single cell Ni-MH or alkaline cell (0.9 to 2.2V input range).
"With a minimum operating voltage of 0.9V, it's possible to operate a portable device with just one battery, ultimately reducing the size of the device or extending the use", said Demetre Kondylis, General Manager for Freescale's Sensors and Analog Products Division.
"Designers and consumers can benefit from product miniaturisation, increased portability and expanded battery life".
The MPC18730 uses Smartmos technology and integrates all functions into a single chip and small 9 x 9mm 64-QFN package, making it an all-in-one product for power management - conserving space and perfect for portable applications.
The MPC18730 is now in production.
The suggested resale price for 10,000-piece quantities is US $2.49.
