Fujitsu Semiconductor FM3 microcontrollers: Microcontrollers offer two-channel Ethernet-MAC support

The Cortex-M3-based FM3 family of 32-bit RISC microcontrollers includes the MB9B610, 410, 310, 210, and 110 series and the MB9A130 series. The MB9B family operates at clock speeds as high as 144 MHz and supports as much as 1 Mbyte of high-speed flash memory and 128 kbytes of RAM, a one- or two-channel Ethernet MAC, USB 2.0 host and slave functions, CAN, and inverter-control timers with as many as three channels. They come in 176- and 144-pin LQFPs and 192-ball BGA packages. Prices start at $7.88 (small volumes). The low-leakage MB9A130 family supports voltages of 1.8 to 5.5V and draws 1.6 μA when using real-time-clock mode under date and time management and 1.2 μA in deep-standby mode using the real-time clock. The device is available in 48- to 64-pin packages with 64 to 128 kbytes of flash memory and as much as 8 kbytes of RAM. Prices start at $2.18.
