The split-gate cell design and thick-oxide tunneling injector offer significant cost and reliability benefits for our customers.The devices use the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontroller devices. The device comes with 17/9 KByte of on-chip flash EEPROM program memory which is divided into 2 independent program memory partitions. The primary partition occupies 16/8 KByte of inter- nal program memory space and the secondary partition occupies 1 KByte of internal program memory space. The flash memory can be programmed via a standard 87C5x OTP EPROM programmer fitted with a spe- cial adapter and 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-system program- ming (ISP) operation. The devices are designed to be programmed in-system on the printed circuit board for maximum flexibility. An example of the bootstrap loader (BSL) in memory, demonstrating initial user program code loading or subsequent user code updating via an ISP operation, is provided on the SST website.

In addition to 17/9 KByte of SuperFlash EEPROM program memory on-chip and 512 x8 bits of on-chip RAM, the device can address up to 64 KByte of external program memory and up to 64 KByte of external RAM.
