Zilog, Inc. Announces New MultiMotor Series Development Kit for its ZNEO and Z8 Encore! XP Devices

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

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.

Zilog Inc. Announces New ZMOTION AC Load Power Controller Reference Design with Advanced Motion Detection Technology

Zilog Inc. introduced its new ZMOTION AC Load Controller Reference Design to expand its portfolio of digital motion detection solutions that target industry requirements for motion sensing and control of lighting and HVAC applications. This reference design demonstrates how to use Zilog's ZMOTION MCU with an IR-based motion detector to control power to an AC load in applications such as lighting and HVAC systems. This reference design uses the 8-pin Z8FS040 ZMOTION MCU to intelligently control a mechanical relay and provides adjustable controls for motion sensitivity, delay time and ambient light level. This new reference design also features Smart Delay technology. With Smart Delay, when motion is detected while the mechanical relay is powered off, the relay's running time is initially set to a maximum of 10 seconds rather than the full delay time set by the Time Delay potentiometer. If additional motion is detected within this 10-second period, the full delay timer set by the potentiometer is used. If additional motion is not detected, then the 10-second delay expires and the load is switched off. This methodology is useful for room occupancy detection and lighting control applications. For example, when the delay time is set for durations greater than 10 seconds and a person enters and leaves a room quickly, the lights are not turned on for the duration of the full delay time; instead, they are turned on for only 10 seconds. When an additional Delayed Detection feature is enabled and motion is detected while the delay time is set to 5 minutes or greater, motion is ignored until the final full minute of the delay cycle. This methodology is useful when the delay is set to a long value and the environment is harsh. It serves to ensure that the light does not remain on due to false motion events. When this feature is not enabled and motion is detected, the system immediately starts looking for motion again, and retriggers the output if motion is detected.
