MICROCHIP 93LC46/SN EEPROM, Microwire, Serial Microwire, 1 Kbit, 128K x 8bit / 64K x 16bit, 2 MHz, SOIC, 8 PinsThe 93LC46 SN is a 1kB MICROWIRE compatible serial Electrically Erasable Programmable Read Only Memory (EEPROM) configured as x8 or x16 bit depending on the external logic of levels of the ORG pin. Advanced CMOS technology makes this device ideal for low power nonvolatile memory applications. Instructions, addresses and write data are clocked into the DI pin on the rising edge of the clock (CLK). The DO pin is normally held in a high Z state except
The 93LC46/SN is a 1kB MICROWIRE compatible serial Electrically Erasable Programmable Read-Only Memory (EEPROM) configured as x8 or x16-bit depending on the external logic of levels of the ORG pin. Advanced CMOS technology makes this device ideal for low power nonvolatile memory applications. Instructions, addresses and write data are clocked into the DI pin on the rising edge of the clock (CLK). The DO pin is normally held in a high-Z state except when reading data from the device or when checking the ready/busy status during a programming operation. The ready/busy status can be verified during an erase/write operation by polling the DO pin, DO low indicates that programming is still in progress, while DO high indicates the device is ready. The DO will enter the high-Z state on the falling edge of the CS. After power-up, the device is automatically in the EWDS mode. Therefore, an EWEN instruction must be performed before any ERASE or WRITE instruction can be executed.

Nice quality, shape not for me
Fit Type: Oversized, Size: Medium, Color: Medium Blue Vintage
This was just too boxy for my body. Material was nice, quality jean material. Color was true to image. It was a little stiff but as you would expect with nice, new and unwashed denim.

Solid basic good denim jacket
Fit Type: Regular, Size: X-Large, Color: Authentic Medium Wash
In direct comparison to Levi’s women’s trucker denim jacket, this one is: slightly heavier denim, less stretchy, less fitted. I kept this one and returned the Levi’s because I wanted the roomier fit. I wish it was a little longer in the body: I’m tall, and it isn’t too short but I’d like a little more length. It feels slightly longer than the Levi’s. I wish the sleeves were longer too. They are probably just right for an average height or shorter person. The armholes could be smaller.
The medium wash is a nice medium blue, fairly even in tone. It doesn’t have a lot of stretch but it’s comfortable. The denim is substantial but not too stiff.
Overall, it’s a standard good quality denim jacket without any peculiar style elements or weird cut. It’s good!

Fabric way to heavy.
Fit Type: Regular, Size: Medium, Color: White
Cute, but material is WAY to heavy, like the heaviest duty denim I've ever seen. Wanted this to be a cute coverup. If you're needing something while breaking broncos or riding your motorcycle would probably be great. I kept it for a while because it was good quality and well made, but it ended up in the donation pile as I'd never wear this.

Old school denim — not stretchy
Fit Type: Regular, Size: X-Small, Color: Authentic Medium Wash
Fabric used is old school denim — not the thin, stretchy stuff that pretty much everything called “denim” is today. It is 99% cotton (20% of which is recycled cotton) and 1% elastane, but I can’t feel any stretch in the fabric. It is a substantial, non-stretchy denim that gives the jacket really good structure. It has a higher end fit and look than the price would suggest.
I wanted a more fitted denim jacket so ordered an XS even though according to the size chart I need a small. (I have a 34.5” bust, 28” waist at 118 pounds 5’4”.) It still buttons over a t shirt or lightweight sweater with freedom for movement/without being tight, but if I wanted a roomy fit or the ability to wear a heavier sweater or sweatshirt underneath and still be able to comfortably button it I would have needed a small. The shoulders are cut broad — I have very broad shoulders and the XS surprisingly fits my shoulders well. This jacket may not be the greatest fit for you if you have very narrow shoulders, unless you are going for an oversized look.
