LC66562B

The LC66562B is a kind of CMOS 4-bit microcontrollers that integrate in a single chip. It is used for control applications including ROM, RAM, I/O ports, serial interfaces, comparator inputs, three-value inputs, timers and interrupt functions. It is available in DIP64S package.

Features of the LC66562B are: (1)a 12- or 16-kbyte on-chip ROM capacity and an on-chip RAM capacity of 512 by 4 bits; (2)support for the full 128 instruction LC66000 series instruction set; (3)fifty four I/O ports; (4)two 8-bit serial interfaces in a 16-bit cascade format; (5)powerful timer and prescaler functions; (6)powerful 11-factor 8-vector interrupt system; (7)low power functions using halt ang hold modes; (8)runaway detection function option.

The absolute maximum ratings at Ta=25, Vss=0 V can be summarized as follows: (1)maximum power supply voltage: -0.3 V to 7.0 V; (2)input voltage: -0.3 V to 15.0 V; (3)total pin current: 75 mA; (4)maximum power dissipation: 600 W at Ta=-30 to 70 ; (5)operating temperature: -30 to 70 ; (6)storage temperature range: -55 to 125 . Then is about its electrical characteristics at Ta=-30 to 70 , Vss=0 V, VDD=3.0 V to 5.5 V. (1)maximum input high current: 5.0 A when VIN=13.5 V; (2)typical comparator offset voltage: ±50 mV, maximum comparator offset voltage: ±300 mV at VIN=0.5 V to VDD; (3)high level threshold voltage: 0.5*VDD to 0.8*VDD, low level threshold voltage: 0.2*VDD to 0.5*VDD.
