The IC89C54/58/64 uses the same powerful instruction set, has the same architecture, and is pin-to-pin compatible with standard 80C52 controller devices. IC89C54/58/64 are just changed internal Flash size, other features are same as standard IC89C52. The IC89C54/58/64 contains a 16K/32K/64K x 8 Flash; a 256 x 8 RAM; 32 I/O lines for either multi-processor communications; I/O expansion or full duplex UART; three 16-bit timers/counters; an eight-source, two-priority-level, nested interrupt structure; and on chip oscillator and clock circuit. The IC89C54/58/64 can be expanded using standard TTL compatible memory. T2/P1.0 T2EX/P1.1 P1.2 P1.3 P1.4 P1.5 P1.6 P1.7 RST RxD/P3.0 TxD/P3.1 INT0/P3.2 INT1/P3.3 T0/P3.4 T1/P3.5 W...
