Data Sheet
A Microchip Technology Company
Memory Organization
The SST89C58RC has separate address spaces for program and data memory.
Program Flash Memory
There are two internal flash memory partitions in the device. The primary flash memory partition (Par-
tition 0) has 32 KByte. The secondary flash memory partition (Partition 1) has 2 KByte.
The 32 KByte primary flash partition is organized as 256 sectors, each sector consists of 128 Bytes.
The primary partition is divided into four logical pages as shown in Figure 5.
The 2K x8 secondary flash partition is organized as 16 sectors, each sector consists also of 128 Bytes.
For both partitions, the 7 least significant program address bits select the byte within the sector. The
remainder of the program address bits select the sector within the partition.
ENBOOT bit in AUXR1 (A2H) determines whether the second partition (Loader Page) is enabled or dis-
abled. If ENBOOT is clear (default), the secondary partition (partition 1) is disabled. ENBOOT is automat-
ically set when either of the following occur: the “Boot-From-Zero” bit is non-zero during reset or when
P1.0 and P1.1 are pulled low while EA# is simultaneously held high on the falling edge of the reset.
If user-code boots from the default boot vector (0xF800) or from the User Boot Vector. The ENBOOT is
set by hardware automatically to enable secondary partition (partition 1).
