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

Perfect suit for boys
Color: Navy Blue, Size: 12 Years, Color: Navy Blue, Size: 12 Years
So thankful for this! This suit was perfect! My son wore this all night playing and the durability of this fabric is on another level. Wasn't too thick, looked really nice, and fabric was really soft. It also blended really well with the suits from Mens Warehouse.

Perfect!
Color: Royal Blue, Size: 12 Years, Color: Royal Blue, Size: 12 Years
I was nervous about purchasing something like this at the last minute. But based on the previous reviews I decided to take a chance. The suit is nice and the material feels really good. Not thin or cheap at all. My son looked so handsome and grown up. He’s on the slim side so he does have extra room but I don’t mind it because he can definitely grow into it. I did purchase a separate tie because I wanted a pattern to complement the blue. I’d definitely purchase again!

Big in waist
Color: Grey, Size: 12 Years
Very nice suit, the material was nice. My son is an average build, the suit fit on the length but unfortunately the pants were huge in the waist. Even with the inside waist adjuster and a belt he couldn't wear them. Which was disappointing because overall the rest of the suit was perfect!

The tops fit perfectly however my 6 year old is very tall and slim so the pants were a little big but at least the adjustable straps on the inside will help..love the color
