Motorola 68HC12
open-in-new
<p>The 68HC12 (also abbreviated as 6812 or HC12) is a <a href="/facts/Microcontroller/MKrnAhnm">microcontroller</a> family from <a href="/facts/Motorola/ztqczx68">Motorola</a> Semiconductor (later from <a href="/facts/Freescale_Semiconductor/mRjBBbeX">Freescale</a> then <a href="/facts/NXP_Semiconductors/naAqdtWq">NXP</a>). Originally introduced in the mid-1990s, the architecture is an enhancement of the <a href="/facts/Freescale_68HC11/7p1pn24u">Freescale 68HC11</a>. Programs written for the HC11 are usually compatible with the HC12, which has a few extra <a href="/facts/Instruction_set/8p8vwUeE">instructions</a>. The first 68HC12 derivatives had a maximum bus speed of 8 <a href="/facts/Hertz/6Wshj5qm">MHz</a> and <a href="/facts/Flash_memory/Cn8JsStx">flash memory</a> sizes up to 128 <a href="/facts/Kilobyte/jIe6t4yv">KB</a>. </p>
