The split-gate cell design and thick-oxide tunneling injector offer significant cost and reliability bene- fits for SST’s customers. The devices use the 8051 instruc- tion set and are pin-for-pin compatible with standard 8051 microcontroller devices. The devices come with 16/24/40 KByte of on-chip flash EEPROM program memory which is partitioned into 2 independent program memory blocks. The primary Block 0 occupies 8/16/32 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 8/16/32 KByte address space; it can also be hidden from the program counter and used as an indepen- dent EEPROM-like data memory. In addition to the 16/24/40 KByte of EEPROM program memory on-chip, the devices can address up to 64 KByte of external program memory. In addition to 1024 x8 bits of on-chip RAM, up to 64 KByte of external RAM can be addressed. 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.
