PRODUCT DESCRIPTION
SST89C54 and SST89C58 are members of the
FlashFlex51 family of 8-bit microcontrollers. The
FlashFlex51 family is a family of embedded
microcontroller products designed and manufactured on
the state-of-the-art SuperFlash CMOS semiconductor
process technology.
As a member of the FlashFlex51 controller family, the
SST89C54/58 uses the same powerful instruction set,
has the same architecture, and is pin-for-pin compatible
with standard 8xC5x microcontroller devices.
SST89C54/58 comes with 20/36 KByte of
integrated on-chip flash EEPROM program memory
using the patented and proprietary Silicon Storage
Technology, Inc. (SST) CMOS SuperFlash EEPROM
technology with the SST field enhancing tunneling
injector split-gate memory cells. The SuperFlash
memory is partitioned into 2 independent program
