Changelog for Master TMS570
===========================
.. _CHANGELOG_FOR_MASTER_TMS570_V1_2_3-0:

v1.2.3-0
------

- fixed wiring of U6601 in schematic and layout
- fixed vendor number of Y6100 (SiT1618BA-32-33N-20.000000) in BOM
- included a suffix in the version declaration

.. _CHANGELOG_FOR_MASTER_TMS570_V1_2_2:

v1.2.2
------

- RTC INTA output circuitry updated to work independent of backup battery
  presence
- adding design variant "production" as primary configuration for board
  production
- adding SBC config to release file (check NOTICE)

.. _CHANGELOG_FOR_MASTER_TMS570_V1_2_1:

v1.2.1
------

- RTC INTA output circuitry updated for compatibility with higher supply
  voltages
- wiring of SBC wake signals rearranged: only ignition signal on WAKE1, RTC and
  CAN1 on WAKE2

.. _CHANGELOG_FOR_MASTER_TMS570_V1_2_0:

v1.2.0
------

- design optimization by removing the second SBC (peripheral SPC), now
  featuring only a single SBC
- fixed wiring of Ethernet PHY in schematic and layout
- control of CAN1 enable and !standby signals directly from MCU instead of port
  expander to increase compatibility with upcoming CAN bootloader
- updated schematic comment related to SBC debug pulse length

.. _CHANGELOG_FOR_MASTER_TMS570_V1_1_5:

v1.1.5
------

- Fixed Farnell order code for 100nF/50V/0402
- Updated project BOM

.. _CHANGELOG_FOR_MASTER_TMS570_V1_1_4:

v1.1.4
------

- Improved SBC wake-up pulse generation circuit by changing value of R7233 to
  470kOhm

.. _CHANGELOG_FOR_MASTER_TMS570_V1_1_3:

v1.1.3
------

- fixed swapped INTA/INTB pinout of U6400 (PCF2131TF)
- added OSHWA logo on PCB
- modified power MOSFET and according control circuitry (Q4400-Q4402) for
  switching external insulation monitor (current rating of previous design was
  too weak)

.. _CHANGELOG_FOR_MASTER_TMS570_V1_1_2:

v1.1.2
------

- fixed assignment of memory devices (MRAM, FRAM, FLASH) to SPI3 chip select
  pins (net labels were swapped)
- split oscillator (Y6100) into two different part numbers and BOM items (one
  part for 20 MHz and 25 MHz)
- added voltage limiting Zener diodes to gates of Q6401 and Q6404
- added 100 |nF| capacitor to "ON" pin of U7300 in order to improve transient
  immunity
- fixed faulty solder paste layer on component U7100
- replaced Ethernet socket J2001 due to availability issues (old part number:
  Wuerth 615008185121, new part number: Wuerth 615008137421)

.. _CHANGELOG_FOR_MASTER_TMS570_V1_1_1:

v1.1.1
------

- added clamping diodes for contactor feedback resistor dividers in order to
  protect inputs of port expander
- added clamping diodes to insulation monitor PWM and OK inputs
- adjusted contactor connectors pinout to match foxBMS 1 Master pinout
- replaced R8014 and R8017 10k resistors with 10R resistors due to amplifier
  gain error
- added placement option to use ADUM6401 as a digital isolator for the CAN2
  interface
- fixed a typo in EMIF connector silk screen
- improved free space around debug connector (debug connector was moved towards
  upper edge of board)
- changed global polygon connect style to relief connect in order to improve
  solderabilty of through-hole connectors
- fixed solder paste areas for Mictor debug connector
- modified all mounting holes to fit Wuerth SMT spacers (outer diameter = 6mm)
- removed interlock high-side switch from default component variant due to
  availability issues
- added hardware board version coding using IO1_0 to IO1_7 of port-expander1

.. _CHANGELOG_FOR_MASTER_TMS570_V1_1_0:

v1.1.0
------

- replaced CAN transceiver with TCAN1043HDQ1 (SOIC-14 package) due to
  availability issues
