Zilog, Inc. Announces New DMX512-A Receiver and Controller Reference Design Using the Z51F0811 and Z51F3220 MCUs for LED Lighting and Sound Controls

Zilog, Inc. announced the release of Zilog’s new DMX Reference Design Kit which includes a DMX512-A Receiver with Z51F0811 MCU and a DMX512-A Controller using Z51F3220 MCU. The receiver functions mainly as a light controller and, alternately, as a sound generator. As a lighting device, the receiver obtains data from the DMX controller that manages the display of four high-bright LEDs using the Z51F0811 MCU’s PWM function. As a sound generator, the receiver activates a speaker that is connected to the Z51F0811 MCU’s buzzer driver. The UART peripheral of the Z51F0811 MCU is used to connect the DMX512-A receiver to the DMX512-A controller. The source code file associated with this reference design,, is available free from the Zilog website. This source code has been compiled using the Keil uVision4 development tool, which is available from Keil. Using Zilog’s DMX512-A controller with Zilog’s Z51F3220 MCU provides an understanding of the DMX512-A protocol, including its theory of operation. This reference design operates in one of three modes: Local Mode – In this mode, five control potentiometers are used to set transmitted light levels for each related Digital Multiplex (DMX) channel; each potentiometer corresponds to a single DMX channel. PC Mode – In this mode, a PC application is required. Demo Mode – In this mode, stored light sequences in the DMX controller’s EEPROM are transmitted to a DMX Universe. This reference design features the following elements: Configurable DMX base slot address via six-position DIP switch, Optically-isolated DMX512-A interface, Four high-brightness LEDs, Buzzer for generating sound output, Ability to manipulate NULL start code (0) and alternate start code (207), Three modes of operation: Local, PC, and Demo.

Zilog Releases New Z8 Encore! XP(R) F6482 Microcontroller for High Performance and Low Power Applications

Zilog, Inc. introduced its Z8 Encore! XP(R) F6482 Series MCU, the latest in Zilog's line of Z8 Encore! XP(R) Flash microcontroller products. These F6482 Series products are based on Zilog's advanced 8-bit eZ8 CPU core and are optimized for low-power and wireless applications, supporting 1.8V to 3.6V low-voltage operations with extremely low Active, Halt, and Stop Mode currents, and offering an assortment of speed and low power options. The I/O capabilities of the F6482 Series MCUs make them suitable for a wide variety of applications including safety and security, utility metering, digital power supervisory, hand-held electronics, and general motor control. The F6482 Series features up to 67 port pins (ports A--J) for general purpose input/output (GPIO); the number of GPIO pins available is a function of package type. Each pin is individually programmable. Zilog's F6482 Series MCUs feature the following functionality: 24MHz eZ8 CPU core, 16KB, 32KB, 60KB or 64KB Flash memory with in-circuit programming capability, 2KB or 3.75KB internal RAM, Up to 128 bytes Non-Volatile Data Storage (NVDS), 12-bit (or 14-bit 2-pass) Analog-to-Digital Converter, 12-bit Digital-to-Analog Converter (DAC), Up to 12 external channels plus dedicated inputs for op amps (2), Temperature sensor, AVDD/2, and bandgap, Internal or external voltage reference and single ended or differential inputs, Integrated LCD driver with blinking and contrast control for up to 96 segments (4 common by 24 segment lines), 128-bit Advanced Encryption Standard (AES) encryption/decryption hardware accelerator according to FIPS PUB 197, Real Time Clock (RTC) supporting both Counter and Clock modes, On-chip temperature sensor, Two on-chip low power analog comparators, Two on-chip, low power operational amplifiers, 8-channel Event System provides communication between peripherals for autonomous triggering, Full speed Universal Serial Bus (USB 2.0) device supporting eight endpoints with integrated USB-PHY, Two full duplex UARTs with Local Interconnect Network (LIN), Digital Addressable Lighting Interface (DALI) and Digital Multiplex (DMX) protocol modes. Support for 9-bit (multiprocessor) and RS-485 driver enable, Two enhanced Serial Peripheral Interface (SPI) controllers, I2C controller which supports Master/Slave modes, Four channel DMA controller with direct or linked-list operation, Three enhanced 16-bit timers with Capture, Compare, and PWM capability, Two additional basic 16-bit timers with interrupt (shared as UART Baud Rate Generator) and 16-bit Multi-Channel Timer which supports four Capture/Compare/PWM modules.

Zilog Announces the Z8F2480 Power Monitor with eZ80F91 Webserver

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.
