PRODUCT DESCRIPTION
The SST89E516RDx and SST89V516RDx are members
of the FlashFlex 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.
The devices come with 72 KByte of on-chip flash
EEPROM program memory which is partitioned into 2
independent program memory blocks. The primary Block 0
occupies 64 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 64 KByte address space; it can also be hid-
den from the program counter and used as an independent
EEPROM-like data memory.
In addition to the 72 KByte of EEPROM program memory
on-chip and 1024 x8 bits of on-chip RAM, the devices can
address up to 64 KByte of external program memory
andup 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 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.
