Sensing machine gains ICE support
Xemics and Phyton have released the first in-circuit emulator (ICE) for the XE8000 microcontroller series and sensing machines.
Microcontroller takes on smart radio applications
New from Xemics the XE88LC06 is a microcontroller for smart radio applications.
The circuit contains a revolutionary block named BitJockey, the equivalent of a UART for the functionality of a wireless connection, which interfaces the microcontroller with any radio transceiver.
The heart of the BitJockey consists of a serialisation block, around which there are a bit encoder and a bit decoder to facilitate standard communication formats (NRZ, Manchester, Miller), as well as input and output FIFO stacks.
"The BitJockey functions like a UART and enables the programmer and processor to concentrate solely on data at the byte level", says Michel Chevroulet, Product Line Manager for Sensing and Radio Machines.
"The bytes of data emitted are converted to an encoded bitstream and sent to the transceiver, and the received encoded bitstream is decoded and converted to bytes.
This frees the processor for other tasks and augments the throughput.
At the same time the code size is reduced meaning that both ROM and RAM needs are lowered".
Applications that will profit from the XE88LC06A include wireless sensors, remote metering, smart toys, wireless tracking and voice over RF.
Any application that relies on batteries for its supply or transmits data over RF can use the XE88LC06A.
This radio machine is completely pin and software backwards compatible to the XE88LC06 chip.
Like its predecessor, the XE88LC06A is based on the high efficiency CoolRISC 8/22bit RISC processor core, includes 520byte of RAM, 22Kbyte of MTP or ROM, a UART, several counters, two clocks and four low-power comparators.
A complete toolset and comprehensive support are available from Xemics and third parties for the XE8000 series, including Ride (C-compiler, assembler, editor, linker, in socket debugger and simulator) and the ProStart II (combined programmer and starter-kit).
An in circuit emulator is available from Phyton.
