PRODUCT DESCRIPTION
The SST89E5xRD2/RD and SST89V5xRD2/RD are
members of the FlashFlex51 family of 8-bit microcontroller
products designed and manufactured with SST’s patented
and proprietary SuperFlash CMOS semiconductor pro-
cess technology. The split-gate cell design and thick-oxide
tunneling injector offer significant cost and reliability bene-
fits for SST’s customers. The devices use the 8051 instruc-
tion set and are pin-for-pin compatible with standard 8051
microcontroller devices.
The devices come with 16/24/40 KByte of on-chip flash
EEPROM program memory which is partitioned into 2
independent program memory blocks. The primary Block 0
occupies 8/16/32 KByte of internal program memory space
and the secondary Block 1 occupies 8 KByte of internal
program memory space.
The 8-KByte secondary block can be mapped to the lowest
location of the 8/16/32 KByte address space; it can also be
hidden from the program counter and used as an indepen-
dent EEPROM-like data memory.
In addition to the 16/24/40 KByte of EEPROM program
memory on-chip, the devices can address up to 64 KByte
of external 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.
