Leo aims at European navigation applications
Fujitsu Microelectronics Europe is releasing its Leo FR-V (Fujitsu RISC-VLIW) chip, based on the FR-V architecture announced last year.
The new microcontrollers capitalise on a powerful FR60 core running at up to 50MHz with a five-stage pipeline, 16bit fixed-length instruction set, and built-in hardware multiplier and barrel shifter.
They were specifically designed for a wide range of embedded control applications including digital home appliances.
The devices integrate 512Kbyte of embedded Flash memory as well as 24Kbyte of embedded SRAM.

Fujitsu Microelectronics Europe and UNIS have introduced the Flash-kit programmer, a high-speed, in-system programming solution for all Fujitsu Flash microcontroller families.
Low-power dual PLL frequency synthesisers
A new series of dual phase-locked loop (PLL) frequency synthesisers designed by Fujitsu feature extremely low power consumption, fast lock times and ultrasmall packaging.
The versatile external interface allows direct access to 16bit SRAM as well as asynchronous ROM (page mode Flash supported).
This, together with its high-speed five-channel direct memory access controller (DMAC), guarantees fast data transfer and simplifies circuit board design.
Serial communication is supported by an I2C interface and up to five USARTs (each with its own baud rate generator).
Four independent ICU (input capture unit) channels are included together with up to eight OCU (output compare unit) channels, four 16bit reload timers and up to six PPG timers.
A maximum 12 channels of 10bit A/D convertor as well as up to three channels of D/A convertor complete this powerful data processing engine.
To enable maximum flexibility, if a resource function is not used the respective pin can be used as standard input or output pin.
A flexible clock concept offers several internal clock frequencies as well as individual settings for the core, the peripherals and the external bus interface.
These, combined with the standard power management function assists the user in finding the optimum tradeoff between performance and power consumption for specific applications.
Implemented in 0.35um CMOS technology, this advanced microcontroller series currently consists of two devices, the MB91F353 in an LQFP-120 package and the MB91F355 with additional features in an LQFP-176 package.
For users needing to start software development before their target board is available, Fujitsu offers the low-cost MB91350 starter kit (SK-91F355-176PMT).
The starter kit has all MB91F355 pins routed to connectors, makes all this device's resources available for evaluation, allows usage of an unregulated external 9V-12V DC power supply and includes a 3.3V internal power supply with power-LED.
Also incorporated are the 12.5MHz main-crystal, two UART transceivers and 8Mbyte Flash, 2Mbyte SRAM and 128Kbyte FRAM.
Additionally, eight user LEDs, a reset button, a reset-LED, and five user buttons configurable for INT4, INT5, TRG4, NMI and ADTG/INT7 are included.
The starter kit is equipped with a graphic board connector (VG96ABC, VG48ABC) and a power supply for graphic boards (5, 3.3 and 2.5V) to enable connection to Fujitsu's graphic controller boards.
The MB91F353/F355 32bit microcontrollers and MB91350 starter kit are available now. Request a free brochure from Fujitsu Microelectronics Europe ...
