00:01STM320151C86 vs N76E003 at 20, which microcontroller wins?
00:07Ok, real talk. You've got 2 tiny chips, a pile of near-identical listings,
00:13and about 10 minutes to decide before you hit order. So I dug through every deal I could find
00:18on the STM320151C86 and lined it up against the N76E003 at 20. 5 listings, real prices, no fluff.
00:28Let's see which one actually earns a spot on your breadboard.
00:32Starting with the 1-10-piece original new STM320151C86 and LQFP48 at 357.
00:40This one's the bulk buy. You get genuinely say Silicon Cortex M3, 32-bit, up to 48MHz,
00:4864KB of flash, 16 of RAM and for a few bucks more than a single unit you can walk away
00:53with 10 of
00:53them. Nearly 5,000 sold at a 4.7, which tells you people keep coming back for it.
01:00If you're spinning up 5 boards on a bench, this is the one.
01:04Now this listing at 376 covers a whole family, the CAT6, the CAT6A revision, the CAT6,
01:11the CBT6, the CBT6A, in both LQFP48 and QFP48. That flexibility is the feature here.
01:20One part number, several package and flash size options, original ST stock, 4.8 rating,
01:25almost 5,000 units gone. You don't have to hunt across 5 different suppliers for one project,
01:32you grab the revision your board actually needs in one place.
01:35Then there's the cheap seat at $1.04, and honestly, this is the listing most of you should
01:40look at first. Single piece, and the part code lists multiple variants including the CAT6A,
01:47CBU6, VCT6, VBT6, RE6 and RCT6. For a one-off prototype, you're talking about a dollar a board
01:55to experiment with. 4.8 rating, over 4,700 sold, so it's not a dead listing. One honest caveat,
02:03at this price, ask for the date code and prove it's genuine before you commit to a big run.
02:09Fourth option, 526 for a single STM-3 to L151C86A in QFP48.
02:15This is the newest silicon revision, and it's the premium end of the table.
02:20If your schematic calls for the A-revision specifically, or you only need one part and
02:25want the freshest date code, this is the cleanest buy. Higher price, but 4.8 rating and 3,500 units
02:31already shipped, folks paying extra for the A-rev aren't disappointed.
02:35Specs used, L151 equals Cortex-SIM 348MHz, 64KB flash, 16KB SRAM, LQFP48.
02:45And 76E003 equals 8-bit 1T8051, 8KB flash, 256B SRAM, TSSOP20.
02:54Skipped, fake urgency, unbeatable hype, at only if channel voice needs it.
02:59Counterfeit caution on the $1.04 listing kept in, it is real risk, not filler.
