Packaging

Type PDIP 18 for through hole builds and SOIC 18 for surface mount builds. Vendor case code 1057 is shown and may refer to a supplier specific case mapping. Please confirm the exact package variant you need

Material Molded epoxy plastic packages with copper leadframe. Lead finish options include lead free and tin lead depending on date code

Size PDIP 18 body width about 0.3 inch with 2.54 mm lead pitch typical body length about 24 to 26 mm. SOIC 18 body width about 7.5 mm with 1.27 mm lead pitch compact height profile for SMT

Pin configuration MCLR Vpp Vdd Vss OSC1 CLKIN OSC2 CLKOUT RA0 RA1 RA2 RA3 RA4 RB0 RB1 RB2 RB3 RB4 RB5 RB6 RB7

Thermal characteristics Typical operating temperature range minus 40 to plus 85 degrees Celsius industrial grade. Typical junction to ambient thermal resistance around 80 to 100 C per W for PDIP and around 120 to 160 C per W for SOIC depending on board copper and airflow. Refer to the datasheet for exact numbers and derating

Electrical properties Typical 5 V operation with variant dependent supply range. Active current scales with clock frequency often from a few mA up to tens of mA at higher speeds. Sleep current in the microamp range. I O pins are low current drivers suitable for logic level interfacing and LED control with appropriate resistors. Maximum clock frequency and voltage limits depend on the specific speed grade and variant. Always verify against the datasheet for your exact part number suffix

Lifecycle

Status Legacy and mature. The PIC16F84 family is widely regarded as not recommended for new designs and some variants are discontinued. Many users have migrated to newer pin compatible PIC16 devices

Recommended alternatives

- PIC16F628A 18 pin replacement path with more RAM and peripherals often used as a drop in upgrade with minor code changes

- PIC16F648A 18 pin with more program memory than 628A and richer peripherals

- PIC16F88 18 pin with ADC and enhanced features a common modern upgrade for 16F84 designs

- PIC16F1847 18 pin enhanced mid range device with much larger program memory RAM and modern peripherals while keeping a similar pinout and footprint
