Evaluation and Demonstration Boards and Kits are increasingly popular with engineers for prototyping and testing out complex new projects. One such popular board is MAL219699003E3, which provides a broad range of features and functions with great flexibility. In this article, we will take a look at the application area and working principles of this particular board.

MAL219699003E3 is a multi-function evaluation board with integrated precision analog circuitry to optimize sensing performance, enabling superior data acquisition accuracy. Its application area is especially suitable for automotive, industrial, medical, instrumentation, and consumer applications and it is well-suited for prototyping and testing a variety of complex projects. The board has a wide range of features, and offers flexibility to accommodate a variety of input signals, enabling engineers to design and build custom Oscilloscopes, Loggers, Data Acquisition Systems, and more.

The board features two MSP430G2553IN20 microcontroller (MCU) chips. This MCU features reduced pin and package count and increased speed compared to its predecessor. The two MCU chips are interconnected through SPI communication, and are further linked to a temp sensor and thermopile sensor to measure temperature and heat respectfully. The module also integrates with voltage regulators, external oscillator clocks, FET transistors, and a user-selectable target voltage reference.

The board also integrates a dual-channel Multi-Input/ Multi-Output (MISO) Analog Signal Conditioner (ASC). This MISO digital-analog conversion (DAC) integrates parallel and serial data-streams to calculate analog voltage level and voltage reference. The M ISO channel’s size and number, as well as its biasing, are user-configurable through carefully designed software. This ASC utilizes current sensing technology to enable engineers to measure current passing through a loaded transistor or FET quickly and accurately.

The MAL219699003E3 evaluation board also includes an embedded high-speed Analog-to-Digital Converter (ADC). This allows for quick and accurate digital representation of voltage and sensor signals even from high-impedance analog signals. The ADC is configured using a 16-bit configurable voltage reference or an external voltage reference. Additionally, the board features an integrated Flash Memory for storing up to 64K of data or further adding applications.

The board further features a SoFEC flash memory, which has been designed to enable faster system startup, reliable data storage, better cold-start data retention, and byte-wise write capability. This reduces the size of data packages while still allowing high-speed digital storage within the board. Additionally, a portable keypad is included, which works with the portable LCD display to allow engineers to select the correct input signal and configure the board for further testing and analysis.

Lastly, the board includes a powerful 13-bit DMA (Direct Memory Access) controller. This enables users to quickly transfer data between memory-mapped and port-fetch based resources such as I/O ports, DMA channels and other devices. The controller also features multiple interrupts, so that users can be notified on important events so that the board can take appropriate action.

Overall, the MAL219699003E3 evaluation board offers a wide range of features and options, enabling engineers to quickly and accurately prototype and test their projects. The board features a broad range of input/output options, has integrated high-resolution analog circuitry, and also features powerful high-speed analog-to-digital converters with single-precision accuracy. Additionally, the board includes integrated Flash Memory, a portable LCD display, and a DMA controller, allowing efficient data transfer.
