P89CV51RB2/RC2/RD2
80C51 with 1 kB RAM, SPI
I Power-down mode with external interrupt wake-up
I Idle mode
2.3 Comparison to P89C51RB2/RC2/RD2 devices
I SPI: The P89CV51RB2/RC2/RD2 devices have an SPI interface that was not present
on the P89C51RB2/RC2/RD2 devices.
I 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 rmware compatibility.
I 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.
I Faster block erase: The erase time for the entire user-code memory of the
P89CV51RB2/RC2/RD2 devices is 150 ms, which is a signicant improvement.
I Larger RAM size: RAM size increased from 512 B to 1 kB.
