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

Only received one of the two filters
I had to return because I only received the cabin filter, not the engine filter. Delivery was delayed and maybe this caused the misplacing of the other part. Not sure. I am placing another order, hoping that it will be complete this time. It is good qualiflty, though.

Buy these, save some $$
Size: size for ASCENT/CROSSTREK/IMPREZA/LEGACY/OUTBACK
Save yourself about $100 by replacing these yourself, we have a Subaru Impreza. Easy to install for a few minutes time spent on YouTube. The dealers make a bundle on this sort of thing.
