MC1468705F2

The MC1468705F2 is a kind of microcomputer unit (MCU) which is an EPROM member of the M146805 CMOS family of low-cost, single-chip microcomputers. This 8-bit microcomputer contains an on-chip oscillator, a CPU, RAM, EPROM, self-programming boostrap ROM, I/O and a timer. MC1468705F2 is a low-power processor designed for low-end to mid-range applications in the consumer, automative, industrial, and communications markets where very low power consumption in an important factor.

There are some features of MC1468705F2 as follows: (1)typical full speed operating power of 10 mV at 5 V; (2)typical WAIT mode power of 3 mW; (3)typical STOP mode power of 40W; (4)fully static operation; (5)64 bytes of on-chip RAM; (6)1079 bytes of UV erased, user programmable ROM (EPROM); (7)16 bidirectional I/O lines; (8)four input-only lines; (9)internal 8-bit timer with software programmable 7-bit prescaler; (10)single 3.0 to 5.5 V supply; (11)versatile interrupt handling; (12)true bit manipulation; (13)addressing modes with indexed addressing for tables; (14)memory mapped I/O; (15)two power saving standby modes: WAIT and STOP.

The following is about the maximum ratings of MC1468705F2: (1)supply voltage, VDD: -0.3 to 8.0 V; (2)all input voltages except OSC1, Vin: VSS-0.5 to VDD+0.5 V; (3)EPROM programming voltage (Vpp pin), Vin: -0.3 to -13.5 V; (4)current drain per pin (excluding VDD, VSS, and Vpp pins): 10 mA ; (5)current drain per pin (Vpp pin): -30 mA; (6)operating temperature range, TA: 0 to 70 for MC1468705F2 and from -40 to +85 for MC1468705F2C; (7)storage temperature range, Tstg: -55 to +150.
