     SST89E516RD2-40-I-NJE Microchip Technology 8-bit Microcontrollers - MCU 64KB+8KB 40MHz

1.Data Sheet

The SST89E516RDx and SST89V516RDx are members of the FlashFlex familyof 8-bit microcontroller products designed and manufactured with SST’s patentedand proprietary SuperFlash CMOS semiconductor process technology. The split-gate cell design and thick-oxide tunneling injector offer significant cost and reli-ability benefits for SST’s customers. The devices use the 8051 instruction set andare pin-for-pin compatible with standard 8051 microcontroller devices

3.Product Description

The SST89E516RDx and SST89V516RDx are members of the FlashFlex family of 8-bit microcon-troller products designed and manufactured with SST’s patented and proprietary SuperFlash CMOSsemiconductor process technology.
The split-gate cell design and thick-oxide tunneling injector offersignificant cost and reliability benefits for SST’s customers. The devices use the 8051 instruction setand are pin-for-pin compatible with standard 8051 microcontroller devices.
The devices come with 72 KByte of on-chip flash EEPROM program memory which is partitioned into2 independent program memory blocks. The primary Block 0 occupies 64 KByte of internal programmemory 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 64 KByte address space; itcan also be hidden from the program counter and used as an independent EEPROM-like data mem-ory.
In addition to the 72 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 externalRAM.
