Description

The T89C5115 is a high performance Flash version ofthe 80C51 single chip 8-bit microcontrollers. It contains a 16-KB Flash memory blockfor program and data.

The 16-KB Flash memory can be programmed either in parallel mode or in serial mode with the ISP capability or with software. The programming voltage is internally gener ated from the standard VCC pin.
