Product Summary

The P87C592EFA is a Single-chip 8-bit microcontroller with CAN controller, derived from the 80C51 microcontroller family. The P87C592EFA uses the powerful 80C51 instruction set and includes the successful PeliCAN functionality of the SJA1000 CAN controller from Philips Semiconductors. The fully static core provides extended power save provisions as the oscillator can be stopped and easily restarted without loss of data. The improved internal clock prescaler of 1:1 achieves a 500 ns instruction cycle time at 12 MHz external clock rate.
