UBA Rev7 STM32 Footprint Change
Budget: $250 – $750 CAD
Job Overview
We require a simple change to an existing PCB design to be done as quickly and reliably as possible in Altium. The change is to the footprint of the main microcontroller on the circuit board.
Current chip:
STM32L496RGT6 / STM32L4A6RGT7 Package: LQFP-64 Package: 12mm x 12mm (0.4mm pitch)
New Chip:
STM32L496QGI6P Package: UFBGA132 Package: 7mm x 7mm (0.5mm pitch)
The job is in 2 parts:
1. Create (or download) the UFBGA132 component of the STM32L496QGI6P into the new schematic. We will provide a table of pin mappings for the new component compared to the old. The new component will include 68 additional pins and the table will confirm whether they should be connected to ground, to power, or floating and whether there is a resistor required. We would ideally like to keep the existing footprint in the schematic, so that there will be 2 parts sitting in parallel but only one would ever be loaded into the build
2. Once the schematic is confirmed, we require the new PCB layout to be updated As with the schematic, ideally we would like to retain the footprint for the existing LQFP-64 package. As defined in the schematic, there may be a few additional resistors that need to be added to the layout to tie new UFBGA132 pins to ground or to power.
