FlashFlex MCU
SST89E52RC / SST89E54RC
Data Sheet
A Microchip Technology Company
Product Description
The SST89E52RC / SST89E54RC are members of the FlashFlex family of 8-bit microcontroller
products designed and manufactured with SST’s 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 our customers.The devices use the 8051 instruction
set and are pin-for-pin compatible with standard 8051 microcontroller devices.
The device comes with 17/9 KByte of on-chip flash EEPROM program memory which is divided
into 2 independent program memory partitions. The primary partition occupies 16/8 KByte of inter-
nal 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 spe-
cial 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 program-
ming (ISP) operation. The devices are designed to be programmed in-system on the printed circuit board for
maximum flexibility. An example of the bootstrap loader (BSL) in memory, demonstrating initial user program
code loading or subsequent user code updating via an ISP operation, is provided on the SST website. The
sample BSL is for the user’s reference only; SST does not guarantee its functionality.
In addition to 17/9 KByte of SuperFlash EEPROM program memory on-chip and 512 x8 bits of on-chip
RAM, the device can address up to 64 KByte of external program memory and up to 64 KByte of external
RAM.
The highly-reliable, patented SST SuperFlash technology and memory cell architecture have a number of impor-
tant advantages for designing and manufacturing flash EEPROMs. These advantages translate into significant cost
and reliability benefits for our customers.
