The M24LR04E-RDW6T/2 is a dynamic NFC/RFID Tag IC with a dual-interface and 4kb electrically erasable programmable memory (EEPROM). It features an I²C interface and can be operated from a VCC power supply. It is also a contactless memory powered by the received carrier electromagnetic wave. The IC is organized as 512 x 8-bit in the I²C mode and as 128 x 32-bit in RF mode. It also features an energy harvesting analogue output, as well as a user configurable digital output pin toggling during either RF write in progress or RF busy mode. The device behaves as a slave in the I²C protocol, with all memory operations synchronized by the serial clock. Read and write operations are initiated by a start condition, generated by the bus master.
- Random and sequential read modes
- Self-timed programming cycle
- Automatic address incrementing
- Enhanced ESD/latch-up protection
- User configurable pin - RF write in progress or RF busy mode
- Analogue pin for energy harvesting
- 4 Sink current configurable ranges
- More than 1 million write cycles
- More than 40-year data retention
- Multiple password protection in RF mode
- Single password protection in I²C mode
Applications
Computers & Computer Peripherals, RF Communications

Looks great on my 67 skin!
Color: Medium
Covers well. I love the color. I bought the medium and tan to cover all seasons. I will mix them as needed. It is sticky all day but it looks great so I'll deal with the sticky! I've tried sooo many tinted high SPF moisturizers and I've finally found one that really looks good.

work well
Color: Light
I recently switched to this mineral sunscreen after having irritation and redness from several chemical sunscreens, and it has made a big difference for me. My skin is sensitive, but this one feels gentle and comfortable without causing burning or itching. It gives me good protection and doesn’t leave my skin feeling worse by the end of the day. Definitely a better option for sensitive skin.

Glowy SPF skin tint, Great skin-like coverage
Color: Medium
I’ve tried a lot of skin tints and this one actually surprised me. The Colorescience Flex Shield gives that “your skin but healthier” look without feeling heavy or greasy. I love that it starts white and adjusts to your skin tone — it blends in really naturally and evens everything out without looking makeup-y.
The finish is glowy but still skin-like, and knowing I’m getting SPF protection at the same time makes it perfect for everyday wear. On busy days this has honestly replaced my foundation.

The best sunscreen I've tried
Size: 8 Fl Oz (Pack of 1)
Both of my parents and both of my maternal grandparents have had skin cancer at least once, so sunscreen is an absolute must for me. I also have sensory processing issues and can't stand sunscreens that smell artificial and/or leave my skin feeling sticky or greasy. Finally, my skin is super sensitive, so I need a sunscreen that I can apply daily without causing a reaction.
I've tried literally hundreds of different sunscreens at all different price points, but because of my rigid list of requirements, I've usually ended up spending a fortune on sensitive-skin-formulated face moisturizers with SPF and using them on all my exposed skin in place of normal sunscreen, because they've been the only options I've found that check every box.
Enter Hawaiian Tropic sport sunscreen. Sure, it doesn't absorb into my skin quite as thoroughly as my favorite SPF moisturizer, but it's also less than 1/6th the price for 8x the quantity. It also has a nice scent that doesn't give me a headache (no overtly chemical smell), only barely leaves my skin feeling greasy, and doesn't cause any irritation with daily application.
It's the only "normal" (non-moisturizer) sunscreen I can stand to wear. I literally have one bottle in my car, a second in my purse, and a third in my medicine cabinet at all times.

My top choice for outdoor sun protection
Size: 8 Fl Oz (Pack of 1)
This sunscreen is so important to use for exposed skin sun protection. Hawaiian Tropic sunscreen ( 50 SPF ) is, in my own personal opinion, the best on the market.
