This week’s EYE on NPI is ALL IN with a fully-integrated Linux-capable chip from Octavo Systems – the OSD32MP157C (https://ift.tt/2AMwla4). Octavo is well known for their integration work. They like to take a main core processor, usually a nice powerful one like an Arm A7 or A8, wire it up to an SRAM chip, add power management and necessary filter capacitors, and package it up in a epoxy’d pick-and-place-able chip.
For example, they took the TI AM335x Sitara Cortex A8 chip (https://ift.tt/38KV2A7) used in the BeagleBone Black (https://ift.tt/2O6OT85) and bonded it to a thin PCB along with SRAM memory chip and power management IC along with a bunch of filter capacitors and other passives. Then encapsulated that PCB and put BGA balls on the bottom so it could be easily integrated. The BeagleBone Pocket (https://ift.tt/2ZQ7smg) is the result, a miniaturized version of the BBB.
In fact, it’s SO INTEGRATED, Octavo did a little ‘stunt hack’ where they hand-soldered wires to the BGA pads and booted Linux successfully – only a few LEDs for indication, and resistors to set the boot mode, are required. (https://ift.tt/2CoCYj2)
OK, so the upshot here is that Octavo has followed up on their earlier smashing success, with a new integration chip, the OSD32MP157C (https://ift.tt/2AMwla4) which combines just about everything you need to implement a microcomputer based on the ST STM32MP1 (https://ift.tt/38FPtD7), a dual Cortex A7 @ up to 800 MHz + Cortex M4 @ 200 MHz processor set with mainline Linux support. Like they did for the AM335x series, this chip contains the main chip, PMIC, EEPROM, crystal and up to a gig of DDR RAM
If you want to see how minimal a connection-set you need, there’s a miniature dev board available too, the OSD32MP1-BRK (https://ift.tt/2Zb73vF) which gives you breakouts for all pads, boot selection switches, USB connection and a microSD card for the Linux filesystem.
These chips are going to be more expensive than the individual parts, but you save a ton of time, and the PCB design and cost will be greatly reduced – you could probably get away with a 2-layer or 4-layer PCB with regular tented vias thanks to the generous 1mm BGA pitch. You can pick up the OSD32MP157C at Digi-Key today, they’re in stock – just search for “OSD32MP157C” (https://ift.tt/2O9fvoL) or visit https://ift.tt/2AMwla4 and put em in your cart!
