PRODUCT DESCRIPTION
The SST89E/V54RC, SST89E/V52RC, and SST89E/
V51RC are members of the FlashFlex51 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 device comes with 17/9/5 KByte of on-chip flash
EEPROM program memory which is divided into 2 inde-
pendent program memory partitions. The primary partition
occupies 16/8/4 KByte of internal program memory space
and the secondary partition occupies 1 KByte of internal
program memory space.
The flash memory can be programmed via a standard
87C5x OTP EPROM programmer fitted with a special
adapter and 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-system programming (ISP) opera-
tion. The devices are designed to be programmed in-sys-
tem on the printed circuit board for maximum flexibility. The
device is pre-programmed with an example of the boot-
strap loader in memory, demonstrating the initial user pro-
gram code loading or subsequent user code updating via
an ISP operation. A sample bootstrap loader is available for
the user’s reference and convenience only; SST does not
guarantee its functionality or usefulness. Chip-Erase opera-
tions will erase the pre-programmed sample code.
In addition to 17/9/5 KByte of SuperFlash EEPROM pro-
gram memory on-chip, the device can address up to 64
KByte of external program memory. In addition to 512 x8
bits of on-chip RAM, up to 64 KByte of external RAM can
be addressed.
