SST89V54RD-33-C-PIE

Microcontroller "51; Interface: SPI, UART; 1KB; 2.7÷3.6VDC; PLCC44

PRODUCT DESCRIPTION

The SST89E5xRD2/RD and SST89V5xRD2/RD are members of the FlashFlex51 family of 8-bit microcontroller

products designed and manufactured with SST’s patented and proprietary SuperFlash CMOS semiconductor process technology. 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.
