Beskrivning
The AT89S8253 is a low-power, high-performance CMOS 8-bit microcontroller with
12K bytes of In-System Programmable (ISP) Flash program memory and 2K bytes of
EEPROM data memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51
instruction set and pinout. The on-chip downloadable Flash allows the program memory to be reprogrammed in-system through an SPI serial interface or by a
conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU
with downloadable Flash on a monolithic chip, the Atmel AT89S8253 is a powerful
microcontroller which provides a highly-flexible and cost-effective solution to many
embedded control applications.
