KYOTO, Japan and SANTA CLARA, Calif., March 7, 2014 /PRNewswire/ -- LAPIS Semiconductor Co., Ltd., a ROHM Group Company, has recently announced the release of 8bit low power microcontrollers designed for sensor management, data collection and processing. The ML610Q793 and ML610Q794G include LAPIS Semiconductor's original high-performance 8bit RISC CPU Core (U8) and a 16bit coprocessor for arithmetic operations, along with analog to digital converters.

Multiple digital interfaces are on chip, including an I²C slave for connecting to a host processor if required. This makes it possible to efficiently control and collect data from multiple sensors, lightening the load on the host processor while reducing system level power consumption. Their robust processing capabilities and low power operation make them ideal for Internet of Things (IoT) applications requiring high performance data collection and processing with minimal power consumption.

These devices operate at up to 4MHz (4MIPS) and include 64Kbytes of FLASH for program storage, 4Kbytes of RAM for program use, and 8Kbytes of Dual Port RAM for data logging. The on-chip coprocessor can perform Multiplication, Division, and Square Root functions, allowing for advanced data analysis. In addition, a variety of interfaces are provided that allow connection to virtually any type of sensor. For analog output sensors there are 3 channels of 12bit Successive Approximation Analog to Digital Conversion (SA-ADC), and for interfacing with digital sensors and wired/wireless communication devices four ports are included: SPI Master, I²C Master, UART, and Synchronous I/O. General Purpose I/O and an I²C Slave I/F for interfacing to a host processor are also available.

The ML610Q793 is available in a thin, compact 48pin WL-CSP (Wafer Level-Chip Scale Package) measuring just 3.1mm x 3.0mm and the ML610Q794G which has all of the features of the ML610Q793 plus a crystal clocking circuit is available in a 48pin QFP package.
