Lapis Semi offers tiny micro for sensor networks
Lapis Semiconductor (formerly OKI Semiconductor) has introduced a sensor network microcontroller in a WL-CSP (wafer-level chip-scale package) measuring 3.1mm x 3.0mm.
The 48-pin ML610Q792 microcontroller is based on an 8-bit propriety RISC processor Core (U8) and has an associated 16-bit coprocessor for arithmetic calculations.
The chip has 64kbyte of flash ROM, which is write supported.
Power consumption is specified at 0.6?A or less in HALT mode.
A development board containing multiple sensors and drivers is provided along with a Software Development Kit (SDK)(2) that includes sample source code and libraries for data logging, calorie calculation, pedometer function, and device drivers for interfacing with the host processor.
