The UPD75312GF-260-3B9 is belonging to the UPD75316 family. The 75316 family features an on-chip LCD controllerand driver with up to 16K bytes of ROM and 1024 nibbles of RAM. The instruction set operates on 1-, 4-, and 8-bit data. Timing is generated by two oscillators. The main oscillator normally drives the CPU and most peripherals. The 32.768-kHz subsystem oscillator provides time keeping when the main oscillator is turned off. Since CMOS power dissipation is proportional to clock rate, the 75316 family provides a software selectable instruction cycle time from 0.95 sec to 122 sec. The STOP and HALT modes turn off parts of the microcontroller for additional power savings. The data retention mode retains RAM contents down to 2.0 V.
The UPD75316 family possesses many features, such as (1) LCD controller/driver for up to 128 segments(32 segment lines; Four common lines; Static, 1/2 or 1/3 bias; LCD resistor ladder available on ROM versions), (2) subsystem oscillator allows watch timer and LCD to operate in power-down modes, (3) 8-bit synchronized serial interface(Full-duplex, three-wire mode; Half-duplex, two-wire mode; NEC serial bus interface (SBI) mode), (4) timers: three channels(8-bit timer/event counter; 8-bit interval timer; Watch (clock) timer: 0.5-sec interrupt request), (5) eight 4-bit registers(Usable as four 8-bit registers), (6) memory-mapped on-chip peripherals, (7) vectored interrupt controller(12 edge detect inputs; Five vectored interrupts), (8) CMOS power saving and battery operation(Normal operating mode; 2.5 mA typical at 5V; HALT mode; 0.5 mA typical; STOP mode; 0.1A typical; Data retention down to 2 volts), (9) operating voltage ranges(ROM and 75P316A OTP/EPROM version; VDD from 2.7 to 6.0 V; 75P308 (standard OTP/EPROM); VDD = 5V±5%), (10) 32 l/O lines(Eight input-only lines; 16 bidirectional I/O lines;Eight 10-volt n-channel, open-drain l/O lines; Direct LED drive from 12 lines; 31 software selectable pullup resistors Eight mask selectable resistors (ROM versions only)), (11) bit sequential buffer(16-bit, bit addressable memory), standard 75X instruction execution times(0.95, 1.91, and 15.3s using 32.768-kHz subsystem clock).
The quality grade of UPD75312GF-xxx-3B9 are standard, which agrees with some differences between special and standard quality grades. For UPD75316GF-xxx-3B9, it can applicated in computers, office equipment, communications, test and measurement, maohine tools, industrial robots, audio and visual equipment, other oonsumer products, and the LEDdirect drive for it is YES. The absolute maximum ratings at TA=25 of UPD75312GF-260-3B9 are (1) VDD(supply voltage)=-0.3 to +7.0V, (2) VPP(supply voltage)=-0.3 to +13.5V, (3) VI2(input voltage)=-0.3 to VDD+0.3V, (4) VO(output voltage)=-0.3 to VDD+0.3V, (5) IOH(high-level output current)=-15 mA peak, (6) IOL(low-level output current)=30 mA peak/15 mA rms, (7) IOL(low-level output current, (8) total ports4,6,7)=100 mA peak/60 mA rms, (9) tSTG(storage temperature)=-65 to 150, (10) tOPT(operating temperature)=-40 to 85.
