PRODUCT DESCRIPTION
The SST89E564RD, SST89V564RD, SST89E554RC, and
SST89V554RC are members of the FlashFlex family of 8-bit
microcontroller products designed and manufactured with
SST’s patented and proprietary SuperFlash CMOS semi-
conductor process technology. The split-gate cell design
and thick-oxide tunneling injector offer significant cost and
reliability benefits for our customers. The devices use the
8051 instruction set and are pin-for-pin compatible with stan-
dard 8051 microcontroller devices.
The devices come with 72/40 KByte of on-chip flash
EEPROM program memory which is partitioned into 2
independent program memory blocks. The primary Block 0
occupies 64/32 KByte of internal program memory space
and the secondary Block 1 occupies 8 KByte of internal
program memory space.
The 8-KByte secondary flash block can be mapped to the
lowest location of the 64-/32-KByte address space; it can
also be hidden from the program counter and used as an
independent EEPROM-like data memory.
In addition to the 72/40 KByte of EEPROM on-chip pro-
gram memory and 1024 x8 bits of on-chip RAM, the
devices can address up to 64 KByte of external program
memory and up to 64 KByte of external RAM.
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 memory, demonstrat-
ing the initial user program code loading or subsequent
user code updating via an IAP operation. A sample boot-
strap loader is available for the user’s reference and conve-
nience only; SST does not guarantee its functionality or
usefulness. Chip-Erase or Block-Erase operations will
erase the pre-programmed sample code.
