Description
MICROCHIP PIC16F84A-20/P 8 Bit Microcontroller, Flash, PIC16F, 20 MHz, 1.75 KB, 68 Byte, 18 Pins, DIPThe PIC16F84A 20 P is a 8 bit 20MHz CMOS Flash EEPROM based Microcontroller. The EEPROM data memory is readable and writable during normal operation (full VDD range). This memory is not directly mapped in the register file space. Instead it is indirectly addressed through the special function registers. The PIC16F84A has a watchdog timer which can be shut off only through configuration bits. It runs off its own RC oscillator for added reliability.
The PIC16F84A-20/P is a 8-bit 20MHz CMOS Flash/EEPROM-based Microcontroller. The EEPROM data memory is readable and writable during normal operation (full VDD range). This memory is not directly mapped in the register file space. Instead it is indirectly addressed through the special function registers. The PIC16F84A has a watchdog timer which can be shut-off only through configuration bits. It runs off its own RC oscillator for added reliability. There are two timers that offer necessary delays on power-up. One is the Oscillator Start-up Timer (OST), intended to keep the chip in reset until the crystal oscillator is stable. The other is the Power-up Timer (PWRT), which provides a fixed delay of 72ms (nominal) on power-up only. This design keeps the device in RESET while the power supply stabilizes. With these two timers on-chip, most applications need no external reset circuitry.
- High performance RISC CPU - 15 special functions hardware register and 8-level deep hardware stack
- High current sink/source for direct LED drive
- EEPROM data retention of >40 years
- In-Circuit Serial Programming� (ICSP�) - Via two pins capability
- Power-on reset (POR), power-up timer (PWRT) and oscillator start-up timer (OST)
- Watchdog timer (WDT) with its own on-chip RC oscillator for reliable operation
- Code protection
- Power saving sleep mode

very happy with my purchase
Color: Brown-F, Color: Brown-F
The quality and craftsmanship of this tray are amazing! I bought it mainly for jewelry photography, and the results turned out even better than I expected ✨
The matte finish is exactly what I needed because it doesn’t reflect light, which makes photographing jewelry and pearls so much easier and gives the photos a much more elevated look 📸
I took these photos at night under white lighting, and I’m honestly so happy with how they turned out. The background looks clean, soft, and aesthetic. Sharing some of my photos here for reference — highly recommend!
