SPI: The P89CV51RB2/RC2/RD2 devices have an SPI interface that was not present
on the P89C51RB2/RC2/RD2 devices.
Smaller block size: The page size decreased from 4 kB to 128 B. These smaller
pages can be erased and reprogrammed using IAP function calls, which makes
practical use of code memory for non-volatile data storage. A page is erased in 30 ms
or less. IAP and ISP code both support 128-B page operations. The IAP and ISP code
uses multiple page-erase operations to emulate the erasing of larger block sizes (8 kB
and 16 kB) to maintain firmware compatibility.
Status bit replaces Status byte: Automatic entry into ISP mode following a reset is
now controlled by one status bit. Its operation is almost identical to that used by the
previous devices, which was based on the zero/non-zero value of the status byte.
Faster block erase: The erase time for the entire user-code memory of the
P89CV51RB2/RC2/RD2 devices is 150 ms, which is a significant improvement.
Larger RAM size: RAM size increased from 512 B to 1 kB.
