Here is the critical update as of 2024-2025: Microchip Technology no longer hosts the standalone HI-TECH C v9.83 installer on their main website. They have transitioned fully to the MPLAB XC8 compiler.

However, because v9.83 was a perpetual license release (and many developers have legal backups), it remains available through:

Important: v9.83 exists in two editions: hitech+c+compiler+for+pic10+12+16+mcus+v983+download+updated

This is the only safe, updated, and legitimate compiler for those MCUs today.

For specific compiler versions like V9.83, and to find updated versions: Here is the critical update as of 2024-2025:

Before diving into the download, let’s address the elephant in the room: Why not just use the newer XC8 compiler?

The HI-TECH C v9.83 compiler uses a proprietary "Omniscient Code Generation" (OCG) engine. Unlike traditional compilers that work file-by-file, OCG looks at your entire program at once. This leads to: Important: v9

For the PIC10 (6-pin), PIC12 (8-pin), and PIC16 (14-40 pin) families, every byte of RAM and word of Flash matters. v9.83 is the last version that many engineers trust for mission-critical firmware where XC8’s updated licensing or different optimization heuristics might introduce unexpected behavior.
