TK68HC705C9A HC05 Microcontroller, 16K Flash
The TK68HC705C9A is an 8-bit microcontroller with the following features:
The Tekmos TK68HC705C9A also has a configuration register that allows the part to be re-configured to replace both the MC68HC705C8A and the MC68HC705C12A. An interesting feature of the configuration register is that it changes the physical pinout of the TK68HC705C9A to match the pinout of the MC68HC705C8A.
The TK68HC705C9A uses Flash to replace the original EPROM program storage. This means that while the original parts were OTP (One Time Programmable), the Tekmos version is fully re-programmable. The TK68HC05C9A is a ROM version of the part that provides a low cost solution for high volume production.
Both the TK68HC705C8A and TK68HC705C9A are available in the 44-pin PLCC (FN), 40-pin PDIP (P) and space saving 44-pin PQFP (FB) packages.
