The PIC18F45K40-I/PT is a large memory, highly integrated 8bit general purpose flash microcontroller in 44 pin TQFP package. This microcontroller with C compiler optimized RISC architecture combines large flash/EE/RAM memory, rich peripheral integration, eXtreme low power (XLP) and 5V support to suit a variety of general purpose applications. The device delivers core independent peripherals such as complementary waveform generator (CWG), window watchdog timer (WWDT), CRC/memory scan, hardware capacitive voltage divider (CVD), zero cross detect, signal measurement timer (SMT), hardware limit timer (HLT) and peripheral pin select for providing increased design flexibility and lower system cost. It features low current power-on reset (POR), configurable power-up timer (PWRTE), brown-out reset (BOR) with fast recovery and low power BOR (LPBOR) option and programming/debug features such as in-circuit debug integrated on-chip and in-circuit serial programming (ICSP) via two pins.
  • 32Kbytes flash program memory, 2048bytes data SRAM and 256bytes data EEPROM
  • Thirty five I/O pins, four 8bit/three 16bit timers and two comparators
  • Thirty five 10bit ADC, one 5bit DAC and one zero cross detect
  • Two EUSART, two I2C/SPI, PPS, RS232, RS485 and LIN interfaces
  • Operating voltage range from 2.3V to 5.5V
  • Operating speed of 0MHz to 64MHz, 62.5ns minimum instruction cycle and auto wake-up on start
  • Fail-safe clock monitor, two-speed oscillator start-up & 3 power saving modes (doze, idle, sleep)
  • Two capture/compare/PWM (CCP) modules and two 10bit pulse width modulators
  • 16MHz internal oscillator, 32KHz low power internal oscillator and auto-baud detect
  • Operating temperature range from -40�C to 85�C

Would not work in my jeep
Color: Textured
This seems like a decent holder, however it is not universal as it would not fit in my jeep. Check to make sure you have the right kind of air vents for it. I could not get it to work for my vehicle as the vents are too wide.

Works great!
Color: Black, Color: Black
This is a very simple, lightweight phone mount. It works well, I’m surprised how securely it fits on the car vent. I’ve tried others and couldn’t get them to fit right. My phone slides into the top and fits nicely. It was easy to install.

No drilling required
Size: Large
I installed this on my 2021 4Runner with the adhesive provided and no drilling. It has been a few months and it’s still solid. I live in Hawaii and the temps in the car have reached over 100* F pretty consistently and the adhesive has held up very well. There are a lot of attachment points for whatever you want to use it for. I only wish they sold the magnetic mount that it comes with so everything can match up. I use it for my phone and baby monitor. I would purchase this again.

Love this ram mount kit
Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121, Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121
All i can say is wow. This is an amazing ram mount kit for my 22 Silverado custom. All the hardware is top notch. The metal is all powder coated black with a nice grey American flag. There are so places to be able to mount addition arms. The phone holder it comes with is solid aluminum with a nice tight spring. I rate this 10/10 and for the price you can not beat it or find another better. I didn’t use the adhesive on the bottom so i can’t speak on that but i can only imagine it is really good as well. Hands down is just as good as the super expensive bulletpoint mount you see advertised. Don’t hesitate to buy.

Looks great
Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121
Fits great and is heavy enough to stay put. I used the adhesive backing to install as I did not want to drill into my truck but it still works well and I have had no issues with it popping out or anything else.
