PRODUCT DESCRIPTION  
The SST89E554A and SST89V554A are members of the  
FlashFlex51 family of 8-bit microcontroller products  
designed and manufactured with SST’s patented and pro-  
prietary SuperFlash CMOS semiconductor process tech-  
nology. The split-gate cell design and thick-oxide tunneling  
injector offer significant cost and reliability benefits for SST’s  
customers. The devices use the 8051 instruction set and  
are pin-for-pin compatible with standard 8051 microcontrol-  
ler devices.  
In addition to the 40 KByte of EEPROM program memory  
on-chip, the devices can address up to 64 KByte of exter-  
nal program memory. In addition to 1024 x8 bits of on-chip  
RAM, up to 64 KByte of external RAM can be addressed.  
The flash memory blocks can be programmed via a stan-  
dard 87C5x OTP EPROM programmer fitted with a special  
adapter and the firmware for SST’s devices. During power-  
on reset, the devices can be configured as either a slave to  
an external host for source code storage or a master to an  
external host for an in-application programming (IAP) oper-  
ation. The devices are designed to be programmed in-sys-  
tem and in-application on the printed circuit board for  
maximum flexibility. The devices are pre-programmed with  
an example of the bootstrap loader in the memory, demon-  
strating the initial user program code loading or subsequent  
user code updating via the IAP operation. The sample  
bootstrap loader is available for the user’s reference and  
convenience only; SST does not guarantee its functionality  
or usefulness. Chip-Erase or Block-Erase operations will  
erase the pre-programmed sample code.  
The devices come with 40 KByte of on-chip flash  
EEPROM program memory which is partitioned into 2  
independent program memory blocks. The primary Block 0  
occupies 32 KByte of internal program memory space and  
the secondary Block 1 occupies 8 KByte of internal pro-  
gram memory space.  
The 8-KByte secondary block can be mapped to the lowest  
location of the 32 KByte address space; it can also be hid-  
den from the program counter and used as an independent  
EEPROM-like data memory.
