The "68HC" prefix is often implied or dropped for the 705 series, which predominantly uses High-Speed CMOS technology. The "E" suffix typically denotes a RoHS-compliant version, meaning it meets environmental standards but is functionally identical to the non-E version. Manufacturers usually maintain a single datasheet (like for the MC68HC705C8) for these core parts, covering all minor variations. In essence, you can consider them interchangeable for most applications.</P> Fri, 04 Jul 2025 05:44:31 GMT marilyn55david 2025-07-04T05:44:31Z https://community.nxp.com/t5/8-bit-Microcontrollers/MC705C8ACPE-vs-MC68HC705ACP-Is-the-only-difference-RoHS-Drop-in/m-p/2072948#M24145 <P>Can anyone tell me if these 2 parts are truly compatible?
