The DS89C450 is pin and functionally compatible with the DS89C440. Designs using the DS89C440 should upgrade to the DS89C450. Software compatibility must be verified in the upgrade process. The DS89C440 has two 16KB banks of FLASH, while the DS89C450 has two 32KB banks of FLASH. If your application code is dependant on the bank size being 16KB, it will need to be modified to work on the DS89C450.
The DS89C430 and DS89C450 offer the highest performance available in 8051-compatible microcontrollers. They feature newly designed processor cores that execute instructions up to 12 times faster than the original 8051 at the same crystal speed. Typical applications will experience a speed improvement up to 10x. At 1 million instructions per second (MIPS) per megahertz, the
microcontrollers achieve 33 MIPS performance from a maximum 33MHz clock rate.
The DS89C440 is a 32kB version of the DS89C450 that is no longer available. The DS89C450 can be used as a drop-in replacement.
