NXP Semiconductors 83C528
the 83C528 • 87C528 — 32k bytes EPROM (described in a separate data sheet) This device provides architectural enhancements that make it applicable in a variety of applications in consumer, telecom and general control systems, especially in those systems which need large ROM and RAM capacity on-chip. The 8XC528 contains a 32k × 8 ROM (83C528), a 512 × 8 RAM, four 8-bit I/O ports, two 16-bit timer/event counters (identical to the timers of the 80C51), a 16-bit timer (identical to the timer 2 of the 80C52), a watchdog timer with a separate oscillator, a • Power control modes: – Idle mode – Power-down mode – Warm start from power-down • CMOS and TTL compatible • Extended temperature ranges • ROM code protection • 7-source and 7-vector interrupt structure • Up to 3 external interrupt request inputs • Two programmable power reduction modes • Termination of Idle mode by any interrupt, • XTAL...
