P89C58X2BN

Product Summary

The P89C58X2BN is a high-performance static 80C51 Philips microcontroller. The P89C58X2BN is manufactured in an advanced CMOS process and contains a non-volatile Flash program memory. The P89C58X2BN supports both 12-clock and 6-clock operation. The P89C58X2BN contains 256 byte RAM, 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 communications, I/O expansion or full duplex UART, and on-chip oscillator and clock circuits. In addition, the device of P89C58X2BN is static a design which offers a wide range of operating frequencies down to zero.
