P89CV51RD2
Description
The P89CV51RB2/RC2/RD2 are three types of 80C51 microcontroller with respectively 16 kB/32 kB/64 kB flash and 1 kB of data RAM. These devices are designed to be drop-in and software-compatible replacements for the popular P89C51RB2/RC2/RD2 devices.
Key Features
- I Smaller block size: The page size decreased from 4 kB to 128 B
- A page is erased in 30 ms or less
- IAP and ISP code both support 128-B page operations
- 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 Larger RAM size: RAM size increased from 512 B to 1 kB
