The HCS08 IP is the same 8-bit HCS08 microcontroller core implemented in Freescale’s MC9S08xx family devices. Building on decades of leadership in the 8-bit microcontroller domain, the HCS08 extends Freescale’s popular 68HC08 architecture, offering improved debug support and additional addressing modes to improve C code efficiency. The HCS08 is fully object code compatible with Freescale’s HC08 and HC05 based micro-controllers, both well-proven workhorses in 8-bit control applications.
The HCS08 also provides a migration path to Freescale’s 32-bit ColdFire® architectures. HCS08 and V1 ColdFire use the same single-pin debug interface and share a common set of development tools. With Freescale’s CodeWarrior integrated development environment, assembly code for the HCS08 can be re-targeted to V1 ColdFire with just a few mouse clicks.
