1 / 84 page  TC9328AF 2004-09-13 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9328AF Portable Audio DTS Controller (DTS-21) The TC9328AF is a single-chip DTS microcontroller for portable audio incorporating 230 MHz prescaller, PLL, and LCD driver. In addition to a 20-bit IF counter, 6-bit A/D converter, serial interface, and buzzer function, the device supports an interrupt function, 8-bit timer/counter, and 8-bit pulse counter. The LCD driver features built-in 1/4 duty, 1/2 bias and a 3 V voltage doubler boosting circuit, implementing stable LCD. The power supply voltage ranges from 0.9 to 1.8 V. Because of its low-current consumption (CPU: 80 µA (max)), the device is suitable for use in digital tuning systems in portable equipment such as headphone stereos. Features • CMOS DTS microcontroller LSI with built-in 230 MHz prescaller, PLL, and LCD driver • Operating voltage: VDD = 0.9 to 1.8 V (typ.: 1.5 V) • Current dissipation: When CPU in operation: IDD = 40 µA (typ.) When PLL in operation: IDD = 6 mA (typ.) (VHF mode) • Operating temperature range: Ta = −10 to 60°C • Program memory (ROM): 16-bit × 8192 steps • Data memory (RAM): 4-bit × 512 words • Instruction execution time: 40 µs • Crystal oscillator frequency: 75 kHz • Stack level: 8 • General-purpose IF counter: 20-bit (CMOS input supported) • A/D converter: 6-bit × 4 channel • LCD driver: 1/4 duty, 1/2 bias, 88 segments (max) • I/O port: CMOS I/O ports: 12 N-channel open drain I/O ports: 24 (max) Output-only port: 1 Input-only ports: 5 (max) • Timer/counter: 8-bit (as timer clock: INTR1/INTR2, instruction cycle: 1 kHz selectable) • Pulse counter: 8-bit up/down counter (input via INTR2 pin) • Buzzer: Built-in four mode: 0.625 to 3 kHz (8 types), Continuous, Single-Shot, 10 Hz Intermittent, or 10 Hz Intermittent 1 Hz Interval • Package: QFP-80 (0.5 mm pitch, 1.4 mm thick) Weight: 0.45 g (typ.) |
