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.
