<p>The MB90F548GSPFR-G-ER is a member of the F2MC-8L family of 8-bit single-chip microcontrollers (MCUs) from the Fujitsu Microcontroller Division. It is a specialized device that contains non-volatile and volatile flash memory elements and a powerful 8-bit CPU core (M3C) capable of executing up to 16 MIPS (million instructions per second) with an internal memory size of 8/16 KBytes. It also features a high-speed 16-bit arithmetic unit and a multiplier coprocessor, along with a serial communication port (SCI), an 8-bit general-purpose timer (GPT), a 12-bit A/D converter for analog inputs, and a system clock/event timer (SCE) for accurate timing and clocking of system resources.</p><p>This device is suitable for embedded applications that require low power consumption and logic clarity, such as the design of power equipment, industrial controllers, medical devices, home and leisure appliances, automotive equipment, and communication systems. Examples of its applications include the design of vehicles’ driver assistant systems (DAS), intelligent sensor networks, factory automation, digital TVs and Wi-Fi applications, and digital printing systems.</p><p>The MB90F548GSPFR-G-ER, along with other members of the same family, has a simple architecture. All configurations begin with a 16-bit CPU core that is able to process both 8- and 16-bit instructions, followed by a wide range of on-chip memories, A/D converters, timers, and other peripherals.</p><p>When the device is powered on, its CPU core executes the stored program from the flash memory element. The data and instructions stored on the ROM or flash ROM are supplied to the CPU core. The CPU core reads these instructions and data and encodes them as commands for a host of peripheral units such as timers, serial ports, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), general input/output (GPIO) ports, bus controllers, and pin multiplexers. Based on these instructions, the CPU core determines which peripheral unit should be used and the actions they should take.</p><p>The on-chip timer is comprised of four general-purpose timer (GPT) and one system clock event timer (SCE). The GPT consists of four modules with different functions such as 8/16-bit counter/timer, pulse-width modulation (PWM), 10-bit up/down counter/timer, and 16-bit up/down counter/timer.</p><p>The peripheral interfaces of the MB90F548GSPFR-G-ER fall into three categories: serial, parallel, and external interrupts. The serial interfaces consist of two serial communication interfaces (SCIs), two HDLCs, and two universal synchronous-asynchronous receiver-transmitters (USARTs). The parallel interfaces include a direct memory access (DMA) controller, an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), and a synchronous serial interface (SSI).</p><p>The device also features an interrupt controller that can manage up to eight external interrupts. The interrupt sources include the SCI, GPT, ADC, DAC, and PWM outputs. All interrupt sources can trigger eight interrupt vectors with individual priority control.</p><p>The device is also packaged in an SSOP20 package that is impervious to dust and contamination. The housing is composed of multiple layers that are laminated together to provide extra strength. This ensures reliable operation despite the external environment and ensures protection from ESD and reverse current clamps.</p><p>In summary, the MB90F548GSPFR-G-ER is an example of a low-powered 8-bit microcontroller with a variety of memory and peripheral offerings. Its simple architecture and included interrupt controller make it perfect for a wide range of embedded tasks.</p>
