OBC EM

This document is containing requirements for OBC EM board.

Usage

• As substitute of OBC FM, which can be used in PC-104 stack
• ...

Requirements

• Same format and connector layout as on OBC FM board (PC-104, piggyback, UART dbg, ?)

Memories

• 4 MB FLASH
• 32 kB EEPROM

Design

• Processor: EFM32GG280F1024
• 48 MHz crystal oscillator
• TPS3824-33 hardware watchdog
• 1 MB SDRAM - R1LV1616RSA-5SI
• 4 MB FLASH - S29JL032J
• 32 kB EEPROM - AT28BV256

FPGA mock

• 3 GPIO as Errors[0:2] signals

Other ICs -> to check connections to proc

• 2x LCL - probably connected only to FPGA
• 2x current sensors
• I2C buffers
• opamp
