Description

The SST89E58RD2A is members of the FlashFlex family of 8-bit microcontroller products designed and manufactured 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 SST customers. The devices use the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontroller devices. The devices come with 24/40 KByte of on-chip flash EEPROM program memory which is partitioned into 2 independent program memory blocks. The primary Block 0 occupies 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 16/32 KByte address space; it can also be hidden from the program counter and used as an independent EEPROM-like data memory. In addition to the 24/40 KByte of EEPROM program memory on-chip and 1024 x8 bits of on-chip RAM, the devices can address up to 64 KByte of external program memory and up to 64 KByte of external RAM.
