ST Micro - LED20003 A monolithic step-down current source with synchronous rectification

The LED2000 is an 850 kHz fixed switching frequency monolithic step-down DC-DC converter designed to operate as precise constant current source with an adjustable current capability up to 3 A DC. The embedded PWM dimming circuitry features LED brightness control. The regulated output current is set connecting a sensing resistor to the feedback pin. The embedded synchronous rectification and the 100 mV typical RSENSE voltage drop enhance the efficiency performance. The size of the overall application is minimized thanks to the high switching frequency and ceramic output capacitor compatibility. The device is fully protected against thermal overheating, overcurrent and output short-circuit. 

The LED2000 is available in VFQFPN 4 mm x 4 mm 8-lead package, and standard SO8.

ST Micro - SPIRIT1, Low data rate, low power Sub 1GHz transceive

The SPIRIT1 is a very low-power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz, but can also be programmed to operate at other additional frequencies in the 300-348 MHz, 387-470 MHz, and 779-956 MHz bands. The air data rate is programmable from 1 to 500 kbps, and the SPIRIT1 can be used in systems with channel spacing of 12.5/25 kHz, complying with the EN 300 220 standard. It uses a very small number of discrete external components and integrates a configurable baseband modem, which supports data management, modulation, and demodulation. The data management handles the data in the proprietary fully programmable packet format also allows the M-Bus standard compliance format (all performance classes). 

However, the SPIRIT1 can perform cyclic redundancy checks on the data as well as FEC encoding/decoding on the packets. The SPIRIT1 provides an optional automatic acknowledgement, retransmission, and timeout protocol engine in order to reduce overall system costs by handling all the high-speed link layer operations. 

Moreover, the SPIRIT1 supports an embedded CSMA/CA engine. An AES 128-bit encryption co-processor is available for secure data transfer. The SPIRIT1 fully supports antenna diversity with an integrated antenna switching control algorithm. The SPIRIT1 supports different modulation schemes: 2-FSK, GFSK, OOK, ASK, and MSK. Transmitted/received data bytes are buffered in two different three-level FIFOs (TX FIFO and RX FIFO), accessible via the SPI interface for host processing.

Freescale - Design News: Let them spin!


Axel Streicher


Posted by Axel Streicher in The Embedded Beat on Nov 13, 2012
A few months back, we talked about the benefits of the electrification of motors in vehicles. Having the right silicon solution available is obviously the key element of the equation, but when software development for motor control for PMSM (permanent magnet synchronous motor) or BLDC (brushless DC) motors starts, the trouble really begins ... It usually takes a developer weeks or even months to implement a stable and optimized PMSM or BLDC motor control solution. And time is money.

Help is on it’s way. Freescale has recently introduced a series of fully loaded motor control development kits, offering developers one of the most integrated automotive motor control solutions on the market today. At the initial stage, seven development kits for Freescale’s Qorivva 32-bit microcontrollers are available to help reduce the time needed to develop motor control applications such as HVAC blowers, electric power steering, engine cooling fans, fuel, water and oil pumps and wipers. Freescale also plans to extend the series over the course of the next 12 months by including more Qorivva kits as well as kits based on the 16-bit S12 based MagniV mixed-signal product lines.

The initial kits feature controller boards powered by the latest Qorivva 32-bit MCUs such as MPC560xP, MPC564xL and MPC560xB families and a 3-phase low-voltage power stage board with the MC33937A FET pre-driver. These come to the developer with complete board schematics, user guides and development kit application notes. Integral to the kits is the source code of the motor control application software, based on the Automotive Math and Motor Control Library Set (MCLib). The kit is complemented by the FreeMASTER application visualization and control tool which allows tuning, debugging and building demos.

As an example, the image shows the 3-phase sensorless BLDC Development Kit with the Qorivva MPC5643L MCU.
