NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any conditions other than those described in the AC and DC Electrical Characteristics section
of this specification is not implied.
2. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
3. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless otherwise noted.


Description

The 89C51RX+ devices contain a non-volatile FLASH program memory (up to 64 k bytes in the 89C51RD+) that is both parallel programmable and Serial In-System Programmable. In-System Programming allows devices to alter their own program memory, in the actual end product, under software control. 89C51RX+ opens up a range of applications that can include the ability to field update the application firmware.

A default serial loader (boot loader) program in ROM allows In-System serial programming of the FLASH memory without the need for a loader in the FLASH code. User programs may erase and reprogram the FLASH memory at will through the use of standard routines contained in ROM.

89C51RX+ are Single-Chip 8-Bit Microcontrollers manufactured in advanced CMOS process and are derivatives of the 80C51 microcontroller family. All the devices have the same instruction set as the 80C51.
