PIC18F65K40-I PT TQFP64 microcontroller

The YINGHUA PIC18F65K40-I PT TQFP64 is an 8-bit microcontroller in a 64-pin TQFP package. It suits engineers developing embedded control applications that require integrated peripherals and low-power operation. This new component is intended for prototype or production board assembly.

64-pin TQFP package implications

The 64-pin thin quad flat pack provides the I/O count needed for designs using multiple communication interfaces or analogue channels. The surface-mount footprint requires reflow soldering equipment and appropriate PCB pad layout. No development tools, cables or software licences are bundled with the device.

Verify voltage and toolchain compatibility

Confirm your design operates within the device supply-voltage range before ordering. Ensure your compiler, programmer and debugger support the PIC18F65K40 core. Check that the 64-pin pinout matches your schematic and that your assembly process handles TQFP components.

Questions about this item

Will the 64-pin TQFP package need rework or replacement during board maintenance?

The 64-pin TQFP package is surface-mounted and intended for permanent installation; replacement requires hot-air rework equipment and soldering skill.

Which limit appears first during sustained operation — flash endurance or thermal budget?

The device provides 40 KB of flash memory; sustained write cycles will reach the flash endurance limit before the thermal budget becomes a constraint.

How much heat does the PIC18F65K40-I dissipate when running continuously at 18 V?

Operating at up to 18 V, the microcontroller draws low current typical for 8-bit cores, so heat dissipation remains minimal during all-day operation.
