SST89C58RC
Data Sheet
A Microchip Technology Company
Product Description
The SST89C58RC is a member of the FlashFlex family of 8-bit micro controllers designed and manu-
factured with SST patented and proprietary SuperFlash CMOS semiconductor process technology.
The split-gate cell design and thick-oxide tunneling injector offer significant cost and reliability benefits
for customers. It uses the 8051 instruction set and is pin-for-pin compatible with standard 8051 micro
controller devices.
With two enhanced SMBus interfaces, the SST89C58RC supports speeds up to 400 Kbps. It comes
with 34 KByte of on-chip flash EEPROM program memory which is divided into two independent pro-
gram memory partitions. The primary partition occupies 32 KByte of internal program memory space
and the secondary partition occupies 2 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 devices. The SST89C58RC is designed to be programmed in-
system on the printed circuit board for maximum flexibility. It is pre-programmed with an example of the
bootstrap loader in memory, demonstrating initial user program code loading or subsequent user code
updating via an ISP operation. The sample bootstrap loader is for the user’s reference only, and SST
does not guarantee its functionality. Chip-Erase operations will erase the pre-programmed sample
code.
In addition to 34 KByte of SuperFlash EEPROM on-chip program memory and 1024 x8 bits of on-chip
RAM, the device can address up to 64 KByte of external program memory and up to 64 KByte of exter-
nal RAM.
The highly-reliable, patented SST SuperFlash technology and memory cell architecture offer a number
of important advantages for designing and manufacturing flash EEPROMs. These advantages trans-
late into significant cost and reliability benefits for customers.
