TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC9317F
DTS Microcontroller (DTS-21)
TC9317F
The TC9317F is a 4 bit CMOS microcontroller for digital tuning
systems. It is capable of functioning at a low voltage of 3 V and
features a built-in PLL and LCD drivers.
The CPU has 4 bit parallel addition and subtraction
instructions (e.g., AI, SI), logic operation instructions (e.g., OR,
AND), composite judging and compare instructions (e.g., TM, SL),
and time-base functions.
The package is an pin 80, 0.5-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 to 3, OUT 1 to 3), there are many dedicated
LCD pins, a PWM output port, a buzzer port, a 6 bit A/D
converter, a serial interface, an IF counter, and other pins. A
Weight: 0.45 g (typ.)
digital tuning system (DTS) is formed in conjunction with
prescalers TD6134AF, TD7101F, or TD7103F.
Low-voltage and low-current consumption make this microcontroller suitable for portable DTS equipment.
Features
x 4 bit microcontroller for digital tuning systems.
x Operating voltage VDD = 1.8 to 3.6 V, with low current consumption because of CMOS circuitry
(with only CPU operating, when VDD = 3 V, IDD = 100 µA max)
x Features built-in 1/3-duty, 1/2-bias LCD drivers and a built-in 3 V booster circuit for the display.
x Data memory (RAM) and ports are easily backed up.
x Program memory (ROM): 16 bit × 4096 steps
x Data memory (RAM): 4 bit × 256 words
x 62-instruction set (all one-word instructions)
x Instruction execution time: 40 µs (with 75 kHz crystal) (MVGS, DAL instructions: 80 µs)
x Many addition and subtraction instructions (12 types addition, 12 types subtraction)
x Powerful composite judging instructions (TMTR, TMFR, TMT, TMF, TMTN, TMFN)
x Data can be transmitted between addresses on the same row.
x Register indirect transfer available (MVGD, MVGS).
x 16 powerful general registers (located in RAM)
x Stack levels: 2
x JUMP or CAL instruction can be used anywhere in the 4096 steps of program memory (ROM) as there are no
pages or fields.
x 16 bit of any address in the 1024 steps in program memory (ROM) can be referenced (DAL instruction).
x Features independent frequency input pins (FMIN and AMIN) and two (DO1 and DO2) phase comparison
outputs for FM and AM.
x In FM or TV mode, a swallow counter is formed with prescalers TD6134AF, TD7101F or TD7103F, and signals
of up to 250 MHz can be received.
x Seven reference frequencies can be selected by program.
x Powerful input/output instructions (IN 1 to 3, OUT 1 to 3)
x Dedicated input ports (K0 to K3) for key input. 33 LCD drive pins (90 segments maximum) available.
x 25 I/O ports: 24 with input/output programmable in 1 bit units, and one output-only port. The three IFIN1,
IFIN2, and DO1 pins can be switched by instruction to IN1 (input-only) or OT (output-only). All
LCD output pins can be switched in 1 bit units to I/O ports. (the S30 pin switches to an IN port).
