Product Summary

The P89C51RD2BA is an 8-bit Flash microcontroller, contains a non-volatile 64kB Flash program memory. The P89C51RD2BA is both parallel programmable and serial In-System and In-Application Programmable. In-System Programming (ISP) allows the user to download new code while the microcontroller sits in the application. In-Application Programming (IAP) means that the microcontroller fetches new program code and reprograms itself while in the system. The P89C51RD2BA allows for remote programming over a modem link. A default serial loader (boot loader) program in ROM allows serial In-System programming of the Flash memory via the UART without the need for a loader in the Flash code. For In-Application Programming, the user program erases and reprograms the Flash memory by use of standard routines contained in ROM.

Parametrics

P89C51RD2BA absolute maximum ratings: (1)Operating temperature under bias: 0 to +70 or -40 to +85℃; (2)Storage temperature range: -65 to +150℃; (3)Voltage on EA/VPP pin to VSS: 0 to +13.0 V; (4)Voltage on any other pin to VSS: -0.5 to +6.5 V; (5)Maximum IOL per I/O pin: 15 mA; (6)Power dissipation (based on package heat transfer limitations, not device power consumption): 1.5 W.
