Consumer memory boosts bandwidth
Device provides performance equivalent to two DDR2 SDRAMs with 16bit I/O, while requiring about 1W less power consumption.
Dual-band dongle is easy intro to Mobile WiMAX
Reference design kit marries Fujitsu's Mobile WiMAX system development kit and its MB86K21 SoC with Infineon's SMARTi WiMAX RF transceiver.
The MB91F487 integrates three fast (1.2us) 10bit A/D convertors, providing 18 channels that allow measurement of motor parameters and other sensor information.
Together with two multifunction timers and PWM (pulsewidth modulation) units, the device offers a cost-effective, single-chip solution for applications which require control of two three-phase motors.
"Three-phase motors are increasingly being used in industrial, automotive and home appliance applications where high-reliability, low acoustic noise, variable speed capability and high-efficiency are requirements", commented Dr Gerhard Roos, Director Automotive and Industrial Business Unit, FME.
"The new MB91480 series is further evidence of Fujitsu's commitment to continuously introduce devices destined for these markets".
Fujitsu's 32bit RISC core (FR), which operates at a clock frequency of 80MHz, is accompanied by an independent micro-DSP unit, supporting digital signal processing such as FIR (finite impulse response) or IIR (infinite impulse response) filtering.
This coprocessor features dedicated instruction, coefficient and variable memory, and can execute a 32 x 32 + 72bit calculation in one machine cycle (12.5ns) in parallel with the CPU.
Other features include two 16bit reload timers, three USARTs with SPI and I2C functionality, timebase and a watchdog timer.
On-chip prefetch and five channels of DMA are included to ensure best possible performance.
The device covers a supply voltage range from 4.0 to 5.5V and a temperature range of -40 to +85C.
Housed in a 100-pin LQFP package, the MB91F487 features 512Kbyte embedded Flash memory and 32Kbyte RAM. Request a free brochure from Fujitsu Microelectronics Europe ...
