Pin to pin and Code to code equivalent with old discontinued NXP's P89V51RD2. And, it does not need programmer since it has built in bootloader. It can be programmed by its UART connection and software on PC called Easy IAP.

The IC is supported in Keil C51 as SST89x516RD2 for compiling and simulation.

Its industry standard practice to do development of 8051 with such IC and later on use cheaper ICs like AT89S52/AT89C51 for production unless you need real big flash like 64kb.
