SA32Bxx series MCU MCAL introduction

Notes: The current MCAL version is 4.3.1

*Schematic diagram of each module of AUTOSAR and each sub-module of Silergy MCAL

1) MCU driver module

???? The services provided by the MCU driver are as follows:

-Software setting;

-Select the state of the microprocessor (stop, sleep, suspend, etc.);

-Configure wake-up behavior;

-Manage internal PLL clock unit;

-Assign initial values ​​to RAM related addresses;

2) WDG driver module

???? This module provides services for controlling and triggering the watchdog hardware and is called by the watchdog management module (WdgM).

3) GPT driver module

???? The universal timer driver provides an interface to access on-chip timers for controller periodic and single events.

4) PORT driver module

???? This module is responsible for the initialization of all Ports in microprocessing.

5) DIO driver module

???? The digital input and output driver provides read and write services for accessing DIO channels, DIO ports and DIO channel groups.

6) ADC driver module

???? The ADC driver is used to abstractly access the analog-to-digital converter. For each input channel, its conversion parameters are configurable.

7) CAN driver module

???? The CAN driver is used for abstract access to the CAN controller and is responsible for sending and receiving messages and switching between different states of the CAN controller (sleep/stop, etc. ) .

8) CRC driver module

???? The Cyclic Redundancy Check (CRC) driver is to provide a data transmission error detection function so that the receiver can receive accurate data during the transmission process of data in the chip.

9) Crypto driver module

???? The encryption driver provides standardized encryption functions and security key/certificate storage interfaces, providing a standard interface for automotive electronic systems to call the underlying encryption hardware.

10) FEE module

???? Flash simulates the EEPROM module, is in the memory hardware abstraction layer (Memory Hardware Abstraction), and cooperates with the Fls module to complete power-off data storage.

11) FLS driver module

???? The Flash driver provides a hardware-independent mechanism for accessing flash memory. The interface services it provides can be used to read, write, compare, and erase flash blocks.

12) LIN driver module

???? The LIN driver provides services for initializing message sending (header, response, sleep mode and wake-up). It is also responsible for receiving responses, checking the current status and verifying wake-up events.

13) PWM drive module

???? The PWM driver provides services to initialize and control the PWM channel in the microcontroller.

14) SPI driver module

???? Responsible for handling SPI serial port data exchange, mainly used for data interaction between MCU and external high-speed devices (such as external FLASH, SBC).

15) CDD_I2C driver module*

???? Responsible for handling I2C serial port data exchange, mainly used for data interaction between MCU and external command devices (such as external EEPROM, external watchdog, etc.).

16) CDD_UART driver module*

???? This module is responsible for processing UART serial port data exchange. It is mainly used for data interaction between MCU and external specific devices. It can also be used as a communication port for Debug.

17) CDD_DMA driver module*

???? This module enables the system to perform complex and efficient data block transmission with minimal CPU intervention to support high baud rate and high real-time communication.

18) CDD SAFETY module*

???? This module is presented in the form of SAFETY PACK, which can meet the requirements of functional safety ASIL-B level. By default, users understand ISO2626 and have read "SA32Bxx_series_safety_manual".
