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).

4 bit I/O ports.
Input and output may be programmed in 1 bit units.
Pins P2-0 through P2-2 can also be used for analog
input to the built-in 6 bit, 2-channel A/D converter.
I/O port 2/A/D

/A/D analog voltage
input
/Reference voltage
input
/PWM output
Conversion time of the built-in A/D converter using the
successive comparison method is 280 Ps. The
necessary pin can be programmed to A/D analog input
in 1 bit units, and P2-2 can be set to the reference
voltage input. Internal power supply (VDD) or constant
voltage (VEE) can be used as the reference voltage. In
addition, constant voltage (VEE) can be input to the
A/D analog input so battery voltage, etc., can be easily
detected. The reference voltage input, for which a
built-in operational amp is used, has high impedance.
Pin P2-3 can also take over the output of the built-in 12
bit PWM. The PWM output is a continuous 73.26 Hz
pulse, whose duty is converted in 256 steps (8 bit). In
addition, a further 4 bit are output every 16 PWM pulse
cycles (218.5 ms).
The A/D converter, PWM output, and their control are
all executed by program.
4 bit I/O ports, whose input/output can be programmed
in 1 bit units.
Pins P3-0 through P3-2 also function as input/output
pins for the serial interface circuit (SIO).
I/O port 3
/Serial data input
/Serial data output
/Serial clock
input-output
/Buzzer output
The SIO serially inputs 4 bit or 8 bit data from the SI
pin at the SCK pin’s clock edge, and serially outputs
data from the SO pin. For the serial operation clock
( SCK ) there is an internal/external option, and a
rising/falling shift option. Moreover, because the SO
pin can be switched to serial input (SI), LSI control and
communication between controllers is simple. All SIO
input pins use built-in Schmitt circuits.
The P3-3 pin also functions as the output for the
built-in buzzer circuit. The buzzer sound can be output
in 254 different tones between 18.75 kHz and 147 Hz,
and at a duty of 50%.
The SIO, the buzzer output, and all associated controls
can be programmed.

I/O port 4~I/O port 6
The input and output of these 16 bit I/O ports can be
programmed in 1bit units.
62 MUTE
Muting output port
1 bit output port. Normally, this port is used for muting
control signal output. This pin can set the internal
MUTE bit to “1” according to a change in the input of
I/O port 1. MUTE bit output logic can be changed; PPL
phase difference can also be output using this pin.
63 TEST
TEST mode control
input
Input pin used for controlling TEST mode. High level
indicates TEST mode, while low level indicates normal
operation. The pin is normally used at low level or
no-connection (NC). (a pull-down resistor is built in).

9. Judge Circuit (J)
When an instruction with the skip function is executed, it judges the skip condition. When the skip
condition is satisfied, the program counter is incremented by two and the subsequent instruction is
skipped.
There are 29 instructions having the skip function. (refer to item 11, instruction function, table of
operational instruction marked “*”.)
10. Table of Instruction Set
Total 62 kinds of instruction sets are available, and instructions are all one word.
