Fujitsu Expands 32-bit Microcontroller Line-up for Motor Control Applications Enabling Control of Two 3-phase Motors with One Chip
Langen, 27th March 2007 — Fujitsu Microelectronics Europe (FME) today announces the MB91F487; the first member of a new series within its 32-bit FR microcontroller family. The MB91480 series is optimised for industrial and home appliance 3-phase motor control and offers a rich feature mix designed to target applications in these markets.
The MB91F487 integrates three fast (1.2µs) 10-bit A/D converters, providing 18 channels that allow measurement of motor parameters and other sensor information. Together with two multi-function timers and PWM (pulse width modulation) units, the device offers a cost-effective, single-chip solution for applications which require control of two 3-phase motors.
"3-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. The new MB91480 series is further evidence of Fujitsu's commitment to continuously introduce devices destined for these markets", commented Dr Gerhard Roos, Director Automotive and Industrial Business Unit, FME.
Fujitsu’s 32-bit RISC core (FR), which operates at a clock frequency of 80MHz, is accompanied by an independent ?DSP unit, supporting digital signal processing such as FIR (Finite Impulse Response) or IIR (Infinite Impulse Response) filtering. This co-processor features dedicated instruction, coefficient and variable memory, and can execute a 32-bits x 32-bits + 72 bits calculation in one machine cycle (12.5ns) in parallel to the CPU.
Other features include two 16-bit reload timers, 3 USARTs with SPI and I²C functionality, timebase and a watchdog timer. On-chip pre-fetch and 5 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 +85°C.
Housed in a 100-pin LQFP package, the MB91F487 features 512kB embedded flash memory and 32kB RAM.
