TTL- and CMOS-Compatible Logic Levels Brown-out Detection Low Power Modes – Power-down Mode with External Interrupt Wake-up – Idle Mode Temperature Ranges: – Commercial (0°C to +70°C) – Industrial (-40°C to +85°C) Packages Available – 40-contact WQFN (Port 4 feature not available) – 44-lead PLCC – 40-pin PDIP (Port 4 feature not available) – 44-lead TQFP All non-Pb (lead-free) devices are RoHS compliant PRODUCT DESCRIPTION The SST89E516RDx and SST89V516RDx are members of the FlashFlex family of 8-bit microcontroller products designed and manufactured with SST’s patented and pro- prietary SuperFlash CMOS semiconductor process tech- nology. The split-gate cell design and thick-oxide tunneling injector offer significant cost and reliability benefits for SST’s customers. The devices use the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontrol- ler devices. The devices come with 72 KByte of on-chip flash EEPROM program memory which is partitioned into 2 independent program memory blocks. The primary Block 0 occupies 64 KByte of internal program memory space and the secondary Block 1 occupies 8 KByte of internal pro- gram memory space. The 8-KByte secondary block can be mapped to the lowest location of the 64 KByte address space; it can also be hid- den from the program counter and used as an independent EEPROM-like data memory. 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 andup to 64 KByte of external RAM. The flash memory blocks can be programmed via a stan- dard 87C5x OTP EPROM programmer fitted with a special adapter and the 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-application programming (IAP) oper- ation. The devices are designed to be programmed in-sys- tem and in-application on the printed circuit board for maximum flexibility. The devices are pre-programmed with an example of the bootstrap loader in the memory, demon- strating the initial user program code loading or subsequent user code updating via the IAP operation. The sample bootstrap loader is available for the user’s reference and convenience only; SST does not guarantee its functionality or usefulness. Chip-Erase or Block-Erase operations will erase the pre-programmed sample code.
