8-bit 80C51 5 V low power 64 kB flash microcontroller

OverviewThe P89CV51RB2/RC2/RD2 are three types of 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 \n\nPrincipal features\n\n\n\n•Supports 12-clock (default) or 6-clock mode selection via ISP or parallel programmer\n\n•6-clock/12-clock mode programmable \"on-the-fly\" by an SFR bit\n\n•Peripherals (PCA, timers, UART) may use either 6-clock or 12-clock mode while the CPU is in 6-clock mode\n\n•128;
