DALLAS Semiconductor, represented by Arrow Electronics , has released the MAXQ microcontroller line. MAXQ2000 RISC microcontroller achieves 3.6 normalised MIPS/mA.
It includes 64kB flash memory, 2kB SRAM, a watchdog timer, two serial ports, an SPI master/slave port, three timers, a 16 x 16 hardware multiplier, 32-bit binary clock and a 132-segment LCD controller. The LCD controller has four common and 36 segment drivers and can support a variety of configurations. Each segment pin can be configured as general-purpose I/O, many of which support interrupt operation.
It is designed for industrial and medical applications that require an LCD controller. The MAXQ2000 uses a 16-bit instruction set, ALU, and data path. Each instruction boils is a simple move instruction, allowing the MAXQ to perform almost all instructions in a single clock cycle.
An evaluation kit is available. The kit seamlessly integrates with an integrated development environment and includes a JTAG interface board for communication with a PC, and an LCD daughter board. The IDE includes a debugger, assembler/linker, a time-limited version of the IAR C-compiler, and a simulator. The Maxim website offers many application notes and software examples to use with the evaluation kit.
The MAXQ2000 is packaged in a 68-pin QFN, and is available directly from Maxim or through authorized distributors.
