Xemics' XE88LC07A is a faster version of the existing XE88LC06A radio chip. Both the chips exploit the BitJockey(tm) to send data over high data rate ISM band transceivers at up to 156 kbps with minimal CPU load. With its 5 MIPS 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 the ISM band transceivers what the 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 8/22 bits XE88LC07A core with its strict 1 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 300 uA per sustained MIPS over the full supply voltage range in programmable version. The ROM version of the XE88LC07A operates down to 1.2 V.

To XE88LC07A also include a low-power oscillator and can keep real-time information for less than 2 uA and it has four low-power comparators that can be enabled for only 1 extra uA. The XE88LC07A is pin compatible with the XE88LC06A. Available now, suggested retail price is $3.06 through distribution for the XE88LC07A in TQFP32 with 22 kB non-volatile program memory at 10k and $1.30 for the ROM version in die form in volume.
