The split-gate cell design and thick-oxide tunneling injector offer significant cost and reliability benefits for SSTs customers. The devices use the 8051 instruction set and 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 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 program memory space. The 8-KByte secondary block can be mapped to the lowest location of the 64 KByte address space it can 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 external RAM. The flash memory blocks can be programmed via a standard 87C5x OTP EPROM programmer fitted with a special adapter and the firmware for SSTs 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) operation. The devices are designed to be programmed in- system and in-application on the printed circuit board for maximum flexibility. The devices are pre-pro- grammed with an example of the bootstrap loader in the memory, demonstrating the initial user pro- gram code loading or subsequent user code updating via the IAP operation. The sample bootstrap loader is available for the users reference and convenience only SST does not guarantee its function- ality or usefulness. Chip-Erase or Block-Erase operations will erase the pre-programmed sample code. 2011 Silicon Storage Technology, Inc. DS25093A 11/11 2
