P89CV51RB2/RC2/RD2
80C51 with 1 kB RAM, SPI
Following a reset condition, under normal conditions, the MCU will start executing code
from address 0000H in the user’s code memory. However if either the PSEN pin was LOW
when reset was exited, or the status bit = 1, the MCU will start executing code from the
boot address. The boot address is formed using the value of the boot vector as the high
byte of the address and 00H as the low byte.
6.3 Flash memory
6.3.1 Flash organization
The P89CV51RB2/RC2/RD2 program memory consists of a 16/32/64 kB block for user
code. The ash can be read or written in bytes and can be erased in 128-B pages. A chip
erase function will erase the entire user code memory and its associated security bits.
There are three methods for erasing or programming the ash memory that may be used.
First, the ash may be programmed or erased in the end-user application by calling
LOW-state routines through a common IAP entry point. Second, the on-chip ISP
bootloader may be invoked. This ISP bootloader will, in turn, call LOW-state routines
through the same common entry point that can be used by the end-user application.
Third, the ash may be programmed or erased using the parallel method by using a
commercially available EPROM programmer which supports this device.
6.3.2 Features
Flash internal program memory with 128-B page erase.
Internal boot block, containing LOW-state IAP routines available to user code.
Boot vector allows user-provided ash loader code to reside anywhere in the ash
memory space, providing exibility to the user.
Default loader providing ISP via the serial port, located in upper-end of program
memory.
Programming and erase over the full operating voltage range.
Read/Programming/Erase using ISP/IAP.
