P87C592EFA

The P87C592EFA is a kind of single-chip 8-bit high-performance microcontroller with on-chip CAN-controller, derived from the 80C51 microcontroller family.P87C592EFA is manufactured in an advanced CMOS process, and is designed for use in automotive and general industrial applications.

Features of the P87C592EFA are:(1) 80C51 central processing unit (CPU); (2) 16 kbytes on-chip ROM,externally expandible to 64 kbytes; (3) 2 x 256 bytes on-chip RAM,externally expandible to 64 kbytes; (4) two standard 16-bit timers/counters; (5) one additional 16-bit timer/counter coupled to four capture and three compare registers; (6) 10-bit ADC with 8 multiplexed analog inputs; (7) two 8-bit resolution Pulse Width Modulated outputs; (8) 15 interrupt sources with 2 priority levels(2 to 6 external interrupt sources possible); (9) five 8-bit I/O ports, plus one 8-bit input port shared with analog inputs.

The absolute maximum ratings of the P87C592EFA can be summarized as:(1): voltage on VDD pin(VDD) is  -0.5 +6.5 V; (2): input voltage on any pin(except CTX0, CTX1, CRX0, CRX1 and EA/VPP)(VI1) is -0.5 V to VDD + 0.5 V; (3): input voltage on EA/VPP to VSS(VI2) is  -0.5 V +13 V; (4): input/output current on any single I/O pin(except from CTX0 and CTX1)(II, IO) is ±10 mA max; (5): total power dissipation(Ptot) is 1.0 W max; (6): storage temperature range(Tstg) is -65°C +150 °C.
