P80C38X2
DESCRIPTION
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. The 8x C31X2/51X2 and 8x C32X2/52X2/54X2/58X2 contain 128 byte RAM and 256 byte RAM respectively, 32 I/O lines, three 16-bit counter/timers, a six-source, four-priority level nested interrupt structure, a serial I/O port for either multi-processor munications, I/O expansion or full duplex UART, and on-chip oscillator and clock circuits. In addition, the devices are low power static designs which offer a wide range of operating frequencies down to zero. Two software
