Ordering number : EN4796A Preliminaly CMOS LSI LC72321 Single-Chip Microcontroller with PLL and LCD Driver Overview The LC72321 is a single-chip microcontroller for use in electronic tuning applications. It includes on chip both LCD drivers and a PLL circuit that can operate at up to 150 MHz. It features a large-capacity ROM, a highly efficient instruction set, and powerful hardware. Functions • Serial I/O • Built-in timer interrupts: 80 µs, 1 ms, 2 ms and 5 ms • Stack: Eight levels • Beep control: Six beep tones (2.08, 2.25, 2.5, 3.0, 3.75, and 4.17 kHz) • Fast programmable divider • General-purpose counters: HCTR for frequency measurement and LCTR for frequency or period measurement • LCD driver for displays with up to 56 segments (1/2 duty, 1/2 bias) • Program memory (ROM): 16 bits × 4095 • Data memory (RAM): 4 bits × 256 • All instructions are single-word instructions • Cycle time: 2.67 µs, 13.33 µs, or 40.00 µs (option) • Unlock FF: 0.55 µs detection, 1.1 µs detection • Timer FF: 1 ms, 5ms, 25ms, 125ms • Input ports: One dedicated key input port and one high breakdown voltage port • Output ports: Two dedicated key output ports, one high breakdown voltage open drain port Two CMOS output ports (of which one can be switched to be used as LCD driver outputs) Seven CMOS output ports (mask option switchable to use as LCD ports) • I/O ports: One switchable between input and output in four-bit units and one switchable between input and output in one-bit units Note: Each port consists of four bits • Program runaway can be detected and a special address set. (Programmable watchdog timer) • Voltage detection type reset circuit • One 6-bit A/D converter • Two 8-bit D/A converters (PWM) • One external interrupt (The LC72321 provides an external interrupt, and internal interrupt and a serial I/O interrupt, one of which can be selected under program control.) • Hold mode for RAM backup • Sense FF for hot/cold startup determination • PLL: 4.5 to 5.5 V • CPU: 3.5 to 5.5 V • RAM: 1.3 to 5.5 V Package Dimensions unit: mm 3174-QIP80E [LC72321] SANYO: QIP80E SANYO Electric Co.,Ltd.
