High-Level Block Diagram Creation

R

rodgerliu

Create a high level mermaid block diagram of this project. Include key component's manufacturer part number in each block whenever possible.

I’ll inspect the project structure and BOM, then create a concise high-level Mermaid block diagram document with MPNs where available.

flux

I found the major blocks: RP2350 MCU, power tree, M40 interface, XY2/encoder DB25, laser safety, I2C expanders, isolated digital I/O, and analog ADS8688-LZM8688 interface. I’m saving the diagram as a project document now.

Created the high-level Mermaid block diagram and saved it in High Level Block Diagram. It includes the main functional blocks and key MPNs from the schematic/BOM, with caveats for connector-only or ambiguous regulator entries.

M40连接器纠正与Sheet 3连接记录
用户确认
  • M40连接器使用 ADAM Tech CFA-50-A-SG-1。
  • 该连接器为 1.27mm pitch，不是2.54mm。
  • 不使用HMS官方SP1137-2作为BOM连接器。
已执行
  • 已更新 J_M40_A 和 J_M40_B 的Schematic属性：
    • Manufacturer Name: ADAM Tech
    • Manufacturer Part Number: CFA-50-A-SG-1
    • Connector Pitch: 1.27mm
    • Role Details: 当前为50Pin原理图等效表示，非2.54mm实物。
  • 仍用两个符号表示一个50Pin接口：
    • J_M40_A: pins 1–40
    • J_M40_B: pins 41–50
Pin表来源
  • 用户上传的AB6607-E三页PDF只有产品摘要，未包含完整Pin表。
  • 已查到HMS官方 Anybus CompactCom M40 Hardware Design Guide，其中3.2.1为Application Connector Pin Overview。
  • 仅按该官方Pin表中可确认的信号进行Schematic连接。
已连接的关键引脚
  • GND: pins 1, 12, 37, 50 → GND
  • 3V3: pins 13, 38 → PWR_3V3
  • SPI: pin45 → MB_SPI_CS; pin20 → MB_SPI_SCK; pin44 → MB_SPI_MISO; pin19 → MB_SPI_MOSI
  • IRQ: pin9 → M40_IRQ
  • RESET: pin8 → GLOBAL_RESET
  • OM: pin36 → M40_PIN_36; pin11 → M40_PIN_11; pin35 → M40_PIN_35; pin3 → M40_OM3_TX_ASI_TX
  • MI/MD: pin27 → M40_MI0_SYNC; pin2 → M40_MI1; pin26 → M40_MD0_DETECT_GND; pin25 → M40_MD1_DETECT_GND
  • DIP/A/D and LED/D pins were assigned named nets per the official table, e.g. M40_DIP1_0_A0_WEH, M40_DIP2_0_D0, M40_LED1B_D8.
  • WE/OE/CS/RX/TX-related pins were named or tied to existing MCU nets where present: M40_WE, M40_PIN_33, M40_CS, M40_PIN_28, M40_ASI_TX_A13.
ERC结果
  • M40相关ERC抽查：J_M40 / M40 keyword未返回Floating Pin、Single Pin Net或Undriven Net警告。
  • 注意：部分M40接口网目前只表示模块侧端口/功能名，未必全部接到MCU；这符合Sheet 3接口符号化阶段，但后续如需实际SPI-only模式，可进一步把未用并行/DIP/LED功能按附录B标No-Connect/No-ERC或接跳线。
禁止事项
  • 不要把M40恢复为2.54mm连接器。
  • 不要把BOM连接器替换为HMS SP1137-2。
  • 不做Layout、Placement或Routing。
