1 / 56 page TC9318AFAG/AFBG 2006-07-27 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9318AFAG,TC9318AFBG Single Chip DTS Microcontroller (DTS-21) The TC9318AFAG and TC9318AFBG are a 4 bit CMOS microcontroller for signal chip digital tuning systems. It is capable of functioning at a low voltage of 3 V and features a built-in prescaler of operating 230 MHz, PLL and LCD drivers. The CPU has 4 bit parallel addition and subtraction instructions (e.g., AI, SI), logic operation instructions (e.g., OR, AN), composite judging and compare instructions (e.g., TM, SL), and time-base functions. The package is an pin 64, 0.5/0.65-mm-pitch quad flat pack package. In addition to various input/output ports and a dedicated key-input port, which are controlled by powerful input/output instructions (IN 1, 2, OUT 1, 2), there are many dedicated LCD pins, a buzzer port, a 6 bit A/D converter, an IF counter, and other pins. Low-voltage and low-current consumption make this microcontroller suitable for portable DTS equipment. Features • 4 bit microcontroller for digital tuning systems. • Operating voltage VDD = 1.8~3.6 V, with low current consumption because of CMOS circuitry (with only CPU operating, when VDD = 3 V, IDD = 80 µA max) • Built-in prescaler (1/2 fixed divider +2 modulus prescaler: fmax ≥ 230 MHz) • Features built-in 1/3-duty, 1/2-bias LCD drivers and a built-in 3 V booster circuit for the display. • Data memory (RAM) and ports are easily backed up. • Program memory (ROM): 16 bit × 4096 steps • Data memory (RAM): 4 bit × 256 words • 60-instruction set (all one-word instructions) • Instruction execution time: 40 µs (with 75 kHz crystal) (MVGS, DAL instructions: 80 µs) • Many addition and subtraction instructions (12 types addition, 12 types subtraction) • Powerful composite judging instructions (TMTR, TMFR, TMT, TMF, TMTN, TMFN) • Data can be transmitted between addresses on the same row. (MVSR instruction) • Register indirect transfer available (MVGD, MVGS instruction). • 16 powerful general registers (located in RAM) • Stack levels: 2 • JUMP or CAL instruction can be used anywhere in the 4096 steps of program memory (ROM) as there are no pages or fields. • 16 bit of any address in the 1024 steps in program memory (ROM) can be referenced (DAL instruction). • Features independent frequency input pins (FMIN and AMIN) and two (DO1 and DO2) phase comparison outputs for FM/VHF and AM. • Seven reference frequencies can be selected by program. • Powerful input/output instructions (IN 1, 2, OUT 1, 2) • Dedicated input ports (K0~K3) for key input. 26 LCD drive pins (69 segments maximum) available. • 17 I/O ports: 10 with input/output programmable in 1 bit units, and 7 output-only port. The 2 IFIN, and DO1 pins can be switched by instruction to IN (input-only) or OT (output-only). • Three back-up modes available by instruction: Only CPU operation, crystal oscillation only, clock stop. TC9318AFAG TC9318AFBG Weight P-LQFP64-1010-0.50E: 0.32 g (typ.) P-LQFP64-1212-0.65A: 0.45 g (typ.) |
