HD6303R

The HD6303R is an 8-bit CMOS micro processing unit which has the completely compatible instruction set with the HD630lVl. l28 bytes RAM, Serial Communication Interface parallel I/O ports and multi function timer are incorporated in the HD6303R. lt is bus compatible with HMCS6800.and can be expanded up to 65k bytes. Like the HMCS6800 family, I/O level is TTL compatible withTSTOV single power supply As the HD6303R is CMOS MPU, power dissipation is extremely low And also HD6303R has Sleep Mode and Stand-by Mode as lower power dissipation mode. Therefore, flexible low power consumption application is possible.

The features of HD6303R can be summarized as (1)object code upward compatible with the HD6800, HD6801, HD6802; (2)multiplexed bus(D0/A0~D7/A7A8~A15), non multiplexed bus (D0~D7, A0~A15); (3)abundant on-chip functions compatible with the HD6301V1; 128 Bytes RAM, 13 Parallel I/O Lines, 16;bit timer, serial communication interface (SCI); (4)low power consumption mode; sleep mode, stand-by mode; (5)minimum instruction execution time, 1s(f=1MHz),0.67s (f=1.5MHz), 0.5s (f=2.0MHz); (6)bit manipulation, bit test instruction; (7)error detecting function; address trap, op code trap; (8)up to 65k bytes address space; (9)wide operation range Vcc=3 to 6V (f = 0.1 0.5 MHz), f= 0.1 to 2.0 MHz (Vcc = 5V±10%).

The absolute maximum ratings of HD6303R are (1)supply voltage VCC: -0.3 or +7.0V; (2)input voltage Vin: -0.3 ~Vcc+0.3V; (3)operating temperature Topr: 0~+70 °C; (4)storage temperature Tstg: -55 +150°C.
