 The XE88LC07A is a higher-speed version of the Xemics XE88LC06A radio machine.
Both devices exploit the company's BitJockey circuit to send data over high-datarate ISM band transceivers at up to 156Kbit/s with minimal CPU load.
With its 5MIPS sustained operation capability, the XE88LC07A core is able to interface to a codec, compress/decompress voice while sending/receiving data to/from a transceiver in pseudo-full-duplex mode.
The BitJockey is to ISM band transceivers what a UART is to line transceivers: it manages the serial to parallel and parallel to serial conversion, leaving the CPU core free for other tasks.
The embedded 8/22bit XE88LC07A core with its strict one clock per instruction architecture (for any instruction, any addressing mode, including multiplication) makes it the most efficient RISC MCU with a current requirement of only 300uA per sustained MIPS over the full supply voltage range in programmable version.
The ROM version of the XE88LC07A operates down to 1.2V.
The XE88LC07A also includes a low-power oscillator and can keep real time information for less than 2uA.
It features four low-power comparators that can be enabled for only 1uA extra current drain.
The XE88LC07A is PIN compatible with the XE88LC06A.
It will be available at the end of Q3 2004.
Suggested retail price is $3.06 (in 10,000-unit quantities) through distribution for the XE88LC07A in TQFP32 with 22Kbyte nonvolatile program memory and $1.30 for the ROM version in die form in volume.
