, means the receivers can be used in PDAs, personal navigation devices, cameras, cellphones, media players and other battery-operated portables. Built-in power management also features a DC-to-DC converter that optimizes power use across a single voltage source.
NXP Semiconductor's new ARM-7-based microcontrollers, the NXP LPC2300 and LPC2400 ARM7 based microcontrollers are said to be the first such devices with two ARM high-speed buses (AHB) that enable simultaneous operation of high-bandwidth peripherals such as Ethernet, USB On-The-Go (OTG), USB Host, CAN, SDRAM and on-chip flash. NXP also claims the LPC2400 is the only ARM7 MCU with a two-port USB Host capability permitting multiple communications applications.
The MCU's dual AHB and three independent direct memory access engines allow multiple high-bandwidth peripherals to operate at the same time without overwhelming the bus. The large array of peripherals available on both the NXP LPC2300 and LPC2400 include two AHB buses, Ethernet, two CAN controllers, four UARTs, SPI, SSP, three IC buses, I2S, RTC, ADC/DAC and SD/MMC Card interface.
The AWG7000 arbitrary waveform generator from Tektronix (Beaverton, Ore.) is billed as the fastest AWG on the market. It's designed to meet test requirements for high-speed serial data buses and wideband digital RF devices. With 5.8-GHz bandwidth, 10-bit resolution, and sample rates up to 20 GS/s, the AWG7000 can produce real-life waveforms with imperfections including noise, jitter, pre/de-emphasis and multi-level signaling up to 10 Gb/s.
The MLX90614 infrared thermometer from Melexis (Concord, N.H.) integrates a custom signal-conditioning block and cost-effective remote monitoring for auto air conditioning, room heaters, home appliances, handhelds and medical equipment. The sensing element is an automotive-grade silicon chip with a thin, micromachined membrane. Output is measured by the chip's thermocouple.
The device's signal-conditioning block, containing a low-noise amplifier, 17-bit ADC and DSP amplifies and digitizes thermocouple output and calculates the object temperature using factory calibration parameters stored in the Eeprom. The SMBus-compatible digital output is fully linearized and compensated for ambient temperature. Temperature resolution is 0.01°C. The standard MLX90614 has an absolute accuracy of 0.5°C over 0 to +50°C and 1°C outside that range.
