DTS Microcontroller (DTS-21)
The TC9327BFG is a 4-bit CMOS microcontroller for
single-chip digital tuning systems, featuring a built-in 230-MHz
prescaler, 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 decision and comparison instructions (e.g., TM,
SL), and time-base functions.
The package is an 80-pin, 0.5 mm-pitch compact package. In
addition to various input/output ports and a dedicated key-input
port, which are controlled by powerful input/output instructions
(IN1 to 3, OUT1 to 3), there are many dedicated LCD pins, a
PWM output port, a BUZR port, a 6-bit A/D converter, a serial
interface, and an IF counter, etc.
Low-voltage and low-current consumption make this
microcontroller suitable for portable DTS equipment.
Weight: 0.45 g (typ.)
Features
• 4 bit microcontroller for single-chip digital tuning systems.
• Operating voltage VDD = 1.8 to 3.6 V, with low current consumption due to CMOS circuitry
(with only the CPU operating when VDD = 3 V, IDD = 100 µA max)
• Built-in prescaler (1/2 fixed divider +2 modulus prescaler: fmax ≥ 230 MHz)
• Features built-in 1/4-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 × 7168 steps
• Data memory (RAM): 4 bit × 256 words
• 62-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 each addition and subtraction)
• Powerful composite decision instructions (TMTR, TMFR, TMT, TMF, TMTN, TMFN)
• Data can be transmitted between addresses on the same row.
• Register indirect transfer available (MVGD, MVGS instructions).
• 16 powerful general registers (located in RAM)
• Stack levels: 2
• Free branching (JUMP instructions) is allowed in the 7168 steps of program memory (ROM) as there are no
pages or fields.
• 16 bits of any address in the 1024 program memory steps (ROM) can be referenced (DAL instructions).
• Features independent frequency input pins (FMIN and AMIN) and two (DO1 and DO2) phase comparator
outputs for FM/VHF and AM.
• Seven kinds of reference frequencies can be selected via software.
• Powerful input/output instructions (IN1 to 3, OUT1 to 3).
• Dedicated input ports (K0 to K3) for key input, 29 LCD drive pins (100 segments maximum) available.
• 29 I/O ports: 27 input/output programmable in 1-bit units, 1 output-only port, and 1 input-only port. The 2 IFIN,
and DO1 pins can be switched by instruction to IN1 (input-only) or OT2 (output-only). In addition, 9 output
LCD output pins for S17 to S25 can be switched to I/O port in 1-bit units.
• Three backup modes available by instruction: Only CPU operation, crystal oscillation only, clock stop.
• Features a built-in 2-Hz timer F/F and a built-in 10/100 Hz interval pulse outputs (internal port for time base).
