via a standard 87C5x OTP EPROM programmer fitted
with a special adapter and firmware for SST89C54/58
devices. During the power-on reset, the SST89C54/58
can be configured as a master for source code storage
or as a slave to an external host for In-Application
Programming (IAP) operation. SST89C54/58 is de-
signed to be programmed 鈥淚n-System鈥?and 鈥淚n-Applica-
tion鈥?on the printed circuit board for maximum flexibility.
The device is pre-programmed with a sample bootstrap
loader in the memory (see Note 1), demonstrating the
initial user program code loading or subsequent user
code updating via the 鈥淚AP鈥?operation.
In addition to 20/36 KByte of SuperFlash EEPROM
program memory on-chip, the SST89C54/58 can ad-
dress up to 64 KByte of program memory external to the
chip. The SST89C54/58 have 256 x 8 bits of on-chip
RAM. Up to 64 KByte of external data memory (RAM)
can be addressed.
The highly reliable, patented SuperFlash technology and
memory cell architecture have a number of important
advantages for designing and manufacturing flash
EEPROMs, when compared with other approaches.
These advantages translate into significant cost and
reliability benefits for our customers.
Note 1: The sample bootstrap loader is for the user鈥檚 reference and
convenience only. SST does not guarantee the functionality
or the usefulness of the sample bootstrap loader. Chip-Erase
or Block-Erase operations will erase the pre-programmed
sample code.

PRODUCT DESCRIPTION
SST89C54 and SST89C58 are members of the
FlashFlex51 family of 8-bit microcontrollers. The
FlashFlex51 family is a family of embedded
microcontroller products designed and manufactured on
the state-of-the-art SuperFlash CMOS semiconductor
process technology.
As a member of the FlashFlex51 controller family, the
SST89C54/58 uses the same powerful instruction set,
has the same architecture, and is pin-for-pin compatible
with standard 8xC5x microcontroller devices.
SST89C54/58 comes with 20/36 KByte of
integrated on-chip flash EEPROM program memory
using the patented and proprietary Silicon Storage
Technology, Inc. (SST) CMOS SuperFlash EEPROM
technology with the SST field enhancing tunneling
injector split-gate memory cells. The SuperFlash
memory is partitioned into 2 independent program
memory blocks. The primary SuperFlash Block 0 occu-
pies 16/32 KByte of internal program memory space and
the secondary SuperFlash Block 1 occupies 4 KByte of
SST89C54/58鈥檚 internal program memory space. The 4
KByte secondary SuperFlash block can be mapped to
the highest or lowest location of the 64 KByte address
space; it can also be hidden from the program counter
and used as an independent EEPROM-like data
memory. The flash memory blocks can be programmed
