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.

Features

P89C51RD2BN features: (1)80C51 Central Processing Unit; (2)On-chip Flash Program Memory with In-System Programming (ISP) and In-Application Programming (IAP) capability; (3)Boot ROM contains low level Flash programming routines for downloading via the UART; (4)Can be programmed by the end-user application (IAP); (5)6 clocks per machine cycle operation (standard); (6)12 clocks per machine cycle operation (optional); (7)Speed up to 20 MHz with 6 clock cycles per machine cycle (40 MHz equivalent performance); up to 33 MHz with 12 clocks per machine cycle; (8)Fully static operation; (9)RAM expandable externally to 64 kB; (10)4 level priority interrupt; (11)8 interrupt sources; (12)Four 8-bit I/O ports; (13)Full-duplex enhanced UART: Framing error detection; Automatic address recognition.
