Product Summary
The P89C51RD2BN is an 8-bit Flash microcontroller. The P89C51RD2BN contains a non-volatile 16kB/32kB/64kB Flash program memory that 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 P89C51RD2BN fetches new program code and reprograms itself while in the system. This allows for remote programming over a modem link.
Parametrics
P89C51RD2BN 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.
