The MB90F394SAPMT-G-JNE1 is a single-chip microcontroller with dedicated hardware and several peripherals, specifically designed to fit the needs of automotive applications. The device has been optimized to save power, with performance and features that are more than suitable for that purpose. The MB90F394SAPMT-G-JNE1 belongs to the class of 8-bit microcontrollers and is part of the MB90F39x family.

The MB90F394SAPMT-G-JNE1 was designed for use in embedded system applications, including those that require automotive-grade environmental and reliability conditions. It is suitable for use in various ECU (electronic control units) such as body, powertrain, and chassis applications. This product is also a powerful device for control applications, such as for monitoring the instrument cluster and for On-Board Diagnostics.

The minimalist design of the MB90F394SAPMT-G-JNE1 offers a range of advanced features that incentivize its use especially in the automotive sector. The internal memory of the controller contains a range of peripherals, used to perform specific tasks such as motor control, advanced power management, battery protection, and communication tasks. Though the device is a single-chip microcontroller, it acts like multiple boards merged to a single one, and consumes much less power compared to conventional MCU products.

This device comes with an internal flash memory of 32 KB, which is sufficient to store code and data. It contains an 8-channel 8-bit analog-to-digital converter, 10-channel 12-bit pulse width modulation unit and up to 43 I/O ports. The device can provide clock frequencies up to 40 MHz and guarantees a minimum voltage of 3.2V and a maximum voltage of 5.5V for full communication.

The MB90F394SAPMT-G-JNE1’s two internal clocks can be used to control the timing of the system and these can be amplified to provide a clock frequency of 32 kHz to 80 MHz.The MB90F394SAPMT-G-JNE1 has a flexible timing unit with a set of capture/compare units and several physical output channels that can be programmed for various functions.The MB90F394SAPMT-G-JNE1’s serial communications interface (SCI) is a highly useful serial peripheral for the microcontroller, for the purpose of communication between different devices or microcontrollers. The SCI can send and receive data and can be used for simple or complex communication protocols or for simple implementations like RS-485 or telemetric.The controller also has an I2C interface, a serial bus communication protocol applied to various maintenance and operational systems. The I2C communication interface of the MB90F394SAPMT-G-JNE1 is used in control systems like CAN, LIN and Safety protocols. The I2C interface can be used to communicate with one or two devices, depending on the load that needs to be supported.

The controller is also equipped with a LIN (Local Interconnect Network) bus, which is used to connect multiple devices in a relatively short distance. With the integrated LIN interface and Flexible Data Rate (FDR) protocol, the MB90F394SAPMT-G-JNE1 is ideal for use in vehicle network systems, such as powertrain and body ECUs.

The CAN (Controller Area Network) protocol is widely used in automotive applications, due to the ability of handling and transmitting large data frames. The MB90F394SAPMT-G-JNE1 offers an integrated CAN controller, with up to 2.5 Mbps of data rate, to fit various communication needs. CAN also supports a wide range of message formats (e.g. SRD, PRD,FF and MM) for quick data transfer and secure exchange.

The timer and clock resources offered by the MB90F394SAPMT-G-JNE1 enable a wide range of system control tasks, ranging from very simple ones to complex tasks such as object detection, motor synchronization and safety features. Timer and clock features include output compare and pulse-width modulation units, as well as a dedicated timer-buzzer control unit. All these features provide a strong system control and functional safety.

The MB90F394SAPMT-G-JNE1 supports many systems such as a communication interface unit, single-wire device interface, SD/MMC interface and a watchdog timer. The integrated watch dog timer helps the system to recover in case of any malfunction; if not reset before the fixed time period, the system will be reset automatically.

In summary, the MB90F394SAPMT-G-JNE1 is an 8-bit microcontroller that is suitable for use in embedded controller applications. The device offers a broad range of advanced features dedicated to automotive-grade applications, including multiple internal peripherals and clock resources, up to 43 I/O ports, serial communication, I2C interface, CAN and LIN network support, and others.
