• 256 Bytes Internal RAM
• Dual Block SuperFlash EEPROM
PRODUCT DESCRIPTION
The SST89C54 and SST89C58 are members of the
FlashFlex51 family of 8-bit microcontroller products
designed and manufactured with the state-of-the-art
SuperFlash CMOS semiconductor process technology.
The device uses the same 8051 instruction set and is pin-
for-pin compatible with standard 8051 microcontroller
devices.
The device comes with 20/36 KByte of on-chip flash
EEPROM program memory using SST’s patented and pro-
prietary CMOS SuperFlash EEPROM technology with
SST’s field-enhancing, tunneling injector, split-gate memory
cells. The SuperFlash memory is partitioned into 2 indepen-
dent program memory blocks. The primary SuperFlash
Block 0 occupies 16/32 KByte of internal program memory
space and the secondary SuperFlash Block 1 occupies 4
KByte of 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 inde-
pendent EEPROM-like data memory. The flash memory
blocks can be programmed via a standard 87C5x OTP
EPROM programmer fitted with a special adapter and firm-
ware for SST’s devices. During the power-on reset, the
device can be configured as a slave to an external host for
source code storage or as a master to an external host for
an in-application programming (IAP) operation. The device

is designed to be programmed in-system and in-application
on the printed circuit board for maximum flexibility. The
device is pre-programmed with an example of the bootstrap
loader in the memory, demonstrating the initial user pro-
gram code loading or subsequent user code updating via
the IAP operation. An example of bootstrap loader is avail-
able for the user’s reference and convenience only. SST
does not guarantee the functionality nor the usefulness of
the sample bootstrap loader. Chip-Erase operations will
erase the pre-programmed sample code.
In addition to 20/36 KByte of SuperFlash EEPROM pro-
gram memory on-chip, the device can address up to 64
KByte of external program memory. In addition to 256 x8
bits of on-chip RAM, up to 64 KByte of external RAM can
be addressed.
SST’s highly reliable, patented SuperFlash technology
and memory cell architecture have a number of impor-
tant advantages for designing and manufacturing flash
EEPROMs. These advantages translate into signifi-
cant cost and reliability benefits for our customers.
