Product Summary
The P89CV51RC2FA is an 80C51 microcontroller with respectively 16 kB/32 kB/64 kB flash and 1 kB of data RAM. These devices are designed to be drop-in and software-compatible replacements for the popular P89C51RB2/RC2/RD2 devices. Both the In-System Programming (ISP) and In-Application Programming (IAP) boot codes are upward compatible.
Parametrics
P89CV51RC2FA absolute maximum ratings: (1)Tamb(bias) bias ambient temperature: -55 to +125 °C; (2)Tstg storage temperature: -65 +150 °C; (3)VI input voltage on EA pin to VSS: -0.5 to +14 V; (4)Vn voltage on any other pin except VSS; with respect to VDD: -0.5 VDD + 0.5 V; (5)IOL(I/O) LOW-level output current per input/output pin: 15mA; (6)Ptot(pack) total power dissipation (per package): 1.5 W.
Features
P89CV51RC2FA features: (1)Supports 12-clock (default) or 6-clock mode selection via ISP or parallel programmer; (2)6-clock/12-clock mode programmable “on-the-fly” by an SFR bit; (3)Peripherals (PCA, timers, UART) may use either 6-clock or 12-clock mode while the CPU is in 6-clock mode; (4)128-B page erase for ef?cient use of code memory as non-volatile data storage; (5)0 MHz to 40 MHz operating frequency in 12× mode, 20 MHz in 6× mode; (6)16/32/64 kB of on-chip flash user-code memory with ISP and IAP; (7)1 kB RAM; (8)SPI (Serial Peripheral Interface) and enhanced UART; (9)PCA (Programmable Counter Array) with PWM and capture/compare functions; (10)Three 16-bit timers/counters.
