Powers of Deduction: When was my Pie Manufactured?

scottiebabe
scottiebabe over 2 years ago

I feel incredibly future to have been able to purchase a RPI and receive it in the mail.

I am also curious with the scarcity of RPIs available is my pie hot out of the oven?

Or has it been sitting in a box for months...

The ESD bag my PI Zero W came in serialized I believe  

image

Ser: 042227752 (not sure what this means)

There are no obvious date marking on the top layer of the pcb

image

Bottom side silkscreen perhaps gives a hint?

image

There is a marking that resembles a datecode but that may related to the pcb fabrication date not pcb assembly date

image

What about the chips?

Looking up the DRAM POP in Microns PN lookup tool

image

image

PN: EDB4432BBPA-1D-F-R

Also referencing Microns general component marking guidelines:

image

Would suggest the DRAM was manufactured datecode '2I' : 18th week 2022 seems plausible.

DCDC: Diodes PAM2306 (3V3 & 1V8), datecode still unknown

image

Wi-Fi Module

image

Appears to be 7th week 2022

Perhaps I can determine the manufacturing date electronically?

Here is the OTP memory block:

Based on https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#otp-registers my Pi's serial number OTP element 28: 0xe77a6d6d 

Looking at /proc/cpuinfo:

scottie@raspberrypi:~ $ cat /proc/cpuinfo
processor       : 0
model name      : ARMv6-compatible processor rev 7 (v6l)
BogoMIPS        : 697.95

CPU implementer : 0x41
CPU architecture: 7
CPU variant     : 0x0
CPU part        : 0xb76
CPU revision    : 7

Hardware        : BCM2835

Serial          : 00000000e77a6d6d
Model           : Raspberry Pi Zero W Rev 1.1

The revision code https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#new-style-revision-codes-in-use just indicates its a PI ZeroW

    I recall that, in the recent articles about Sony's investment, Eben had stated that 70% of the manufacturing capacity was going to commercial buyers.

    I knew Raspberry Pi was popular but I had no idea they were producing 2 million in a good quarter.

    Indeed its adoption must go beyond students and professionals in the engineering field.
