About the Item

Philips P80C32X2 8-bit microcontroller with 256B RAM

P80C32X2BA | P80C32X2BN | P80C32X2FA | P80C32X2FN

80C51 8-bit microcontroller family, low voltage, low power, high speed.

The Philips microcontrollers described in this data sheet are high-performance static 80C51 designs incorporating Philips’ high-density CMOS technology with operation from 2.7 V to 5.5 V. They support both 6-clock and 12-clock operation.

In addition, the devices are low power static designs which offer a wide range of operating frequencies down to zero. Two software selectable modes of power reduction – idle mode and power-down mode – are available. The idle mode freezes the CPU while allowing the RAM, timers, serial port, and interrupt system to continue functioning. The power-down mode saves the RAM contents but freezes the oscillator, causing all other chip functions to be inoperative. Since the design is static, the clock can be stopped without loss of user data. Then the execution can be resumed from the point the clock was stopped.
