SJA1124AHG中文资料Quad LIN master transceiver with LIN master controller数据手册恩XP规格书

描述 Description

The SJA1124 is a quad Local Interconnect Network (LIN) master channel device. Each of the four channels contains a LIN master controller and LIN transceiver with master termination. LIN master frames are transferred to the physical LIN bus via the LINphysical layer.
The SJA1124 is primarily intended for in-vehicle subnetworks usingbaud rates up to 20 kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016(12 V LIN) and SAE J2602-1.
A Serial Peripheral Interface (SPI) and an interrupt output provide the interface between the SJA1124 and a microcontroller

特性 Features

General
• Four LIN master channels:
• LIN master controller
• LIN transceiver
• LIN master termination consisting of a diode and a 1 kΩ ±10 % resistor
• Very low current consumption in Low Power mode with wake-up via SPI or LIN
• Option to control an external voltage regulator via the INHN output
• Bus signal shaping optimized for baud rates up to 20 kBd
• SPI for communicating with the microcontroller:
• SPI used for configuration, control, diagnosis and LIN data transfer
• Flexible SPI length from 3 bytes to 18 bytes
• Output status pin signals SPI operational state
• Interrupt output pin: interrupts can be configured individually
• Facilitates synchronous LIN frame transmission across multiple SJA1124 devices
• VIO input for direct interfacing with 3.3 V and 5 V microcontrollers
