G65SC21P2

The G65SC21P2 is designed as one kind of CMOS peripheral communications interface adapter which provides programmed microprocessor control of up to two peripheral devices. G65SC21P2's most significant feature is its internal baud rate generator, allowing programmable baud rate selection from 50 to 19200 baud.

Features of the G65SC21P2 are:(1)CMOS process technology for low power consumption;(2)1direct replacement for NMOS 6521 and 6821 devices manufactured by others;(3)low programmable 8-bit bidirectional I/O ports for peripheral device interfacing;(4)programmable interrupt and status registers;(5)full-duplex or half-deplex operating modes;(6)selectable 5, 6, 7, 8 or 9 bit transmission rates;(7)false start bit detection;(8)serial echo mode;(9)four operating frequencies 1, 2, 3 and 4 MHz;(10)available in 40-pin dual-in-line or 44-pin PLCC package.

The absolute maximum ratings of the G65SC21P2 can be summarized as:(1)supply voltage: -0.3 V to +7.0 V;(2)input voltage: -0.3 V to Vpp+0.3 V;(3)operating temperature: -40 to +85 ;(4)storage temperature: -55 to +150 .
