Zilog Announces the Z8F2480 Power Monitor with eZ80F91 Webserver
Aug 12 14
Zilog introduced its Z8F2480 Power Monitor with eZ80F91 Webserver to expand its portfolio of reference designs which accelerate time to market solutions. This new reference design targets remote-operated AC motors and remote-operated commercial/architectural lighting control applications. This reference design integrates a Z8F2480-based AC power monitor with Zilog’s eZ80F91 Webserver Module to showcase the capability of an optically-isolated Z8F2480 MCU-based power monitor to measure AC input voltage, AC load current, voltage/current phase shift, the power factor of the load, and to communicate via a standard Ethernet interface and webserver. The Z8F2480 MCU and the eZ80F91 Webserver Module are connected for easy mounting. The load is powered via a single-phase AC line with voltage in the range of 90 V to 240 V RMS at 50 or 60 Hz. The Z8F2480 MCU-based power board provides current to a power load and provides optically-isolated I2C signals to communicate with the eZ80F91 Module. This reference design can be used as a basis for developing systems that can control different power installations, including motors and lighting ballasts. Key Features: this reference design features the following elements: 90 –240 V AC RMS input voltage range; Load current up to 3 amps; less than 5 mA average current consumed from an AC line in either monitoring or standby modes; 3750 V isolation voltage between the AC line and the eZ80F91 MCU. Potential Applications: this reference design can be used to develop a number of applications; the brief list below offers examples: remote-operated commercial or architectural lighting monitors; remote-operated AC motors or other devices; remote UPS monitoring; remote power usage monitoring; Green Energy power generation monitoring; HVAC power usage monitoring. Zilog continues to expand its array of new turn-key reference designs to assist and accelerate design time. Zilog’s Z8F2480 Power Monitor with eZ80F91 Webserver reference design is now available for customers that place orders through the Zilog Store.
Zilog, Inc. Announces New MultiMotor Series Development Kit for its ZNEO and Z8 Encore! XP Devices
Mar 11 14
Zilog, Inc. introduced its new MultiMotor Series Development Kit to aid in the development of motor control applications using an assortment of Zilog MCUs designed specifically for motor control environments. Zilog's Z16FMC MCU-based MultiMotor Series Development Kit (ZMULTIMC100ZCOG) is a complete application-specific platform for creating a design featuring a Zilog motor control MCU Module connected to a 3-phase MultiMotor Series Development Board. A 24 V DC/3200 RPM 3-phase motor is included with the Kit, though several motor types are supported, including BLDC, PMSM, and ACIM. Control algorithms including sensored, sensorless, trapezoidal, sinusoidal, and vector are also supported in this MultiMotor Series. The 2.5" x 3.0" Motor Control Module provides circuitry that interfaces its Z16FMC MCU to an external development PC running the Zilog Developer Studio II (ZDS II) Integrated Development Environment (IDE), and to the 3-Phase MultiMotor Series Development Board. Other key features of the MultiMotor Series Development Kit include switches to control the speed, direction, and stop/run settings of the motor, plus 32MB of SPI Flash memory for data logging. The Z16FMC Series Flash microcontroller that is central to the MultiMotor Series Development Kit is based on Zilog's advanced ZNEO 16-bit CPU core, which is optimized for motor control applications in which the control of single and multi-phase variable-speed motors is crucial. Target applications are large appliances, small appliances, and HVAC systems. The key features of the Z16FMC MCU include a 20 MHz, 16-bit optimized single-cycle CISC core, up to 128 KB of in-circuit programmable Flash memory, 4 KB internal RAM with 16-bit access, plus highly integrated digital/analog peripherals such as a 12-bit PWM module with three complementary pairs (or six independent PWM outputs), a fast 12-channel, 10-bit Analog-to-Digital Converter (ADC) for current sampling and back-EMF detection, three standard 16-bit timers with capture, compare, and PWM capability, an analog comparator for current limiting or overcurrent shutdown, an operational amplifier, a 4- channel DMA controller, and a flexible communication interface including a UART with LIN and IrDA, I2C, and enhanced SPI.
Zilog Announces New Microstepper Motor Control Reference Design Featuring the Z8F1680 MCU
Nov 14 13
Zilog Inc. introduced its new Microstepper Motor Control Reference Design to expand its portfolio of reference designs that target motor control applications and provide accelerated time-to-market solutions. Zilog's Z8F1680 MCU-based Microstepper Motor Reference Design is a complete and easy-to-use platform that demonstrates the feature set of the Z8F1680 microcontroller, which is optimized for microstepper motor control. This Microstepper Motor Reference Design drives a unipolar stepper motor using the Z8F1680 MCU's onboard analog comparators for one-shot feedback current limiting. It also uses the Z8F1680 MCU's multichannel timer as a microstepper sine/cosine current generator. The Microstepper Motor Reference Design is designed to be operated either by battery or an external power supply of 5V DC to 12V DC. The Microstepper Motor Reference Design employs Zilog's full-featured Z8F1680 MCU to receive user commands which drive a unipolar stepper motor. Microstepping, or sine/cosine microstepping, is a stepper motor drive technique in which the current in the motor windings is controlled to approximate a sinusoidal waveform.
