1. General description

The TJA1085 is a FlexRay active star coupler that can connect up to 4 branches of a

FlexRay network. The TJA1085 is compliant with the FlexRay electrical physical layer

specification V3.0.1 (see Ref. 1

Several TJA1085 devices can be connected via their TRXD0/1 interfaces to increase the

number of branches in the network. A dedicated Communication Controller (CC) interface

allows for integration into an ECU. The TJA1085 supports low-power management by

offering bus wake-up capability along with battery supply and voltage regulator control.

The TJA1085 meets industry standards for EMC/ESD performance and provides

enhanced bus error detection, low current consumption and unmatched asymmetric delay

performance.

The TJA1085 also fulfills the JASPAR requirements as defined by the Japanese car

industry.

The internal supply voltage to the state machine is denoted by VDIG. VBUF is an auxiliary supply and is only needed for forwarding the wake-up pattern when VCC is not available. 6.

TJA1085 NXP Semiconductors FlexRay active star coupler 6.4 Wake-up The TJA1085 supports the following wake-up mechanisms: • Remote wake-up via the bus (wake-up pattern or dedicated wake-up frame) • Local wake-up via pin LWU • Activity on the inner star interface (pins TRXD0 and TRXD1) Any wake-up event will generate a WU interrupt. A remote wake-up on a branch will generate an EVENT_BRx interrupt to indicate the branch where the wake-up pattern or dedicated data frame was detected.

TJA1085 NXP Semiconductors FlexRay active star coupler 6.9 Branch operating modes Each of the four branches in the TJA1085 features six branch operating modes: • Branch_Off All branches are in Branch_Off mode when the TJA1085 is in AS_PowerOff or AS_Reset mode. The transmitter, normal receiver, low-power receiver and bus error detection are disabled. The bus pins are floating. • Branch_LowPower All branches are in Branch_LowPower mode when the TJA1085 is in AS_Standby or AS_Sleep mode.
PAGE 17
TJA1085 NXP Semiconductors FlexRay active star coupler 6.9.1.3 Branch_Disabled An overtemperature event (TEMP_HIGH flag set) triggers a transition from Branch_Normal to Branch_Disabled in all branches. If an overtemperature event triggered the transition from Branch_Normal to Branch_Disabled, all branches return to Branch_Normal when the overtemperature problem has been resolved (TEMP_WARN flag reset). The ‘Branch_Disabled’ and ‘Branch_Normal’ commands can be used to enable/disable individual branches.

PAGE 20
TJA1085 NXP Semiconductors FlexRay active star coupler 6.10 SPI interface The TJA1085 contains a bidirectional 16-bit Serial Peripheral Interface (SPI) for communicating with a host. The SPI allows the host to configure the TJA1085 and to access error and status information. 6.10.1 Register access The SPI supports full duplex data transfer, so status information is read out on pin SDO while control data is being shifted in on pin SDI.
PAGE 21
TJA1085 NXP Semiconductors FlexRay active star coupler The assignment of control and status register addresses is detailed in Table 6. Data can only be written to the Control and Configuration registers (status registers are read-only by definition). Therefore the state of bit 12 is only evaluated when these registers are being accessed. Table 6.
PAGE 22
TJA1085 NXP Semiconductors FlexRay active star coupler 6.10.2.1 Control register The read/write Control register allows the host controller to set the operating modes and to switch the TJA1085 between HC and AP modes. Table 7.
PAGE 23
TJA1085 NXP Semiconductors FlexRay active star coupler 6.10.2.2 Configuration register The read/write Configuration register allows the host controller to configure a number of TJA1085 parameters and functions. Table 8.
PAGE 24
TJA1085 NXP Semiconductors FlexRay active star coupler Autonomous Error Confinement (AEC): Setting the AEC bit enables the autonomous error confinement feature of the TJA1085. When AEC is enabled, a bus error (TxE_BRx = 1) triggers a transition from Branch_Normal to Branch_FailSilent. AEC is disabled by default. Bus Failure Timer (BFT): Setting the BFT bit enables the bus failure timer. When the BFT is enabled, pulses shorter than tto(BFT) are ignored, resulting in more robust bus error detection.
PAGE 25
TJA1085 NXP Semiconductors FlexRay active star coupler 6.10.2.3 Interrupt Status register The Interrupt Status register is read-only. When the TJA1085 sets a bit in this register, it triggers a falling edge on pin INTN. Bits PWON, WU, SPI_ERROR and HC_ERROR are reset after a successful read operation. The remaining bits are reset after the flag (or flags) that triggered the interrupt has been reset and a successful read operation has been performed (see Section 6.7). Table 9.
PAGE 26
TJA1085 NXP Semiconductors FlexRay active star coupler PWON: A PWON interrupt is generated to signal a power-on event. The PWON interrupt status bit is set when the TJA1085 leaves AS_PowerOff or AS_Reset. It is reset after a successful read operation on the Interrupt Status register. WU: A WU interrupt indicates the occurrence of a wake-up event. The WU interrupt status bit is set when a wake-up event is detected on a branch (WU_BRx = 1), on TRXD0/1 (WU_TRXD = 1), or on LWU (WU_LOCAL = 1).
PAGE 27
TJA1085 NXP Semiconductors FlexRay active star coupler The HC_ERROR interrupt status bit is set when the host requests an illegal mode transition (as defined in the Section 6.8.1 and Section 6.9.1). It is reset after a successful read operation on the Interrupt Status register. TEMP_ERROR: A TEMP_ERROR interrupt signals the presence of an overtemperature condition.
PAGE 28
TJA1085 NXP Semiconductors FlexRay active star coupler 6.10.2.4 General Status register The read-only General Status register contains status information not included in the Interrupt status register. Table 10.
PAGE 29
TJA1085 NXP Semiconductors FlexRay active star coupler WU_LOCAL: WU_LOCAL is set when a local wake-up event is detected. A WU interrupt is generated. WU_LOCAL is reset after the General Status register has been read successfully or when the TJA1085 switches from AS_Normal to AS_Standby or AS_Sleep. This ensures that a new wake-up event will be detected. WU_TRXD: WU_TRXD is set when a wake-up event is detected on the TRXD0/1 interface. A WU interrupt is generated.
PAGE 30
TJA1085 NXP Semiconductors FlexRay active star coupler TEMP_WARN: TEMP_WARN is set when the junction temperature rises above the temperature warning level, generating a TEMP_ERROR interrupt. If bit latching is enabled (BIT_LATCHING = 1), TEMP_WARN will remain set until the General Status register has been read, after which it will reflect the current ‘live’ situation (set when Tj > Tj(warn) and reset when Tj < Tj(warn) with no activity on the bus or on the CC and TRXD0/1 interfaces).
PAGE 31
TJA1085 NXP Semiconductors FlexRay active star coupler 6.10.2.5 Branch X status registers There is a dedicated read-only status register for each branch, i.e. there are four Branch X status registers in total. Each register contains relevant status information of a branch. Table 11.
PAGE 32
TJA1085 NXP Semiconductors FlexRay active star coupler STATE_BRx: Bits STATE_BRx indicate the current branch operating mode. WU_BRx: WU_BRx is set when a remote wake-up event is detected on a branch. A WU interrupt is generated along with an EVENT_BRx interrupt to indicate the branch where the wake-up pattern or dedicated data frame was detected. WU_BRx is reset after the Branch Status register has been read successfully or when the TJA1085 switches from AS_Normal to AS_Standby or AS_Sleep.
