Jitter suppression verified for mixed-signal ICs
Fujitsu Microelectronics Europe has been working with London-based Toric to verify embedded jitter-suppressing macros based on Anti-Jitter Cell technology
Today's control systems require flexible timer architectures with the capability of generating high precision output signals a requirement.
The real-time capturing of signals and events is also an important consideration.
To address these needs, the MB91F464A microcontroller provides eight free-running timers, which act as a timebase for eight ICU and six OCU modules, eight reload timers, 12 channels of 16bit PPG and a real-time clock module that can operate on the 4MHz main crystal, or on the 32kHz subclock.

For communication and networking, this microcontroller offers a C-CAN, I2C-bus, and five LIN-USARTs.
The on-chip PLL creates an internal operating frequency of up to 80MHz and can use a clock modulator to improve EMC behaviour.
Other features include a fast 21-channel A/D convertor, 416Kbyte of embedded Flash memory that features protected read-out and 16Kbyte of embedded RAM.
On-chip prefetch and five channels of DMA are included to ensure best possible performance.
The microcontroller comes in an RoHS-compliant 100-pin QFP package and functions over the operating temperature range of -40 to +105C covering a supply voltage range of 3 to 5.5V.
Engineering samples will become available in Q4 2006 and will be accompanied by a full set of development tools such as starter kits, hardware- and software-debugger including OSEK operating system support.
