P89V51RD2FN

The P89V51RD2FN is designed as one kind of 8-bit 80C51 5 V low power 16/32/64 kB flash microcontroller device, P89V51RD2FN is also capable of IAP, allowing the flash program memory to be reconfigured even while the application is running. And this device supports both parallel programming and in serial ISP.

Features of the P89V51RD2FN are:(1)80C51 CPU; (2)5 V operating voltage from 0 MHz to 40 MHz; (3)16/32/64 kB of on-chip flash user code memory with ISP and IAP; (4)Supports 12-clock (default) or 6-clock mode selection via software or ISP; (5)SPI and enhanced UART; (6)PCA with PWM and capture/compare functions; (7)Four 8-bit I/O ports with three high-current port 1 pins (16 mA each); (8)Three 16-bit timers/counters; (9)Programmable watchdog timer; (10)Eight interrupt sources with four priority levels; (11)Second DPTR register; (12)Low EMI mode (ALE inhibit); (13)TTL- and CMOS-compatible logic levels; (14)Brownout detection.etc.

The absolute maximum ratings of the P89V51RD2FN can be summarized as:(1)bias ambient temperature: -55 to +125 °C;(2)storage temperature: -65 to +150 °C;(3)input voltage: -0.5 to +14 V;(4)voltage on any other pin: -0.5 to VDD + 0.5 V;(5)LOW-level output current per input / output pin: 20 mA or 15 mA;(6)total power dissipation (per package): 1.5 W.
