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 = 130 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).Pinout
DescriptionThe TC93P27F 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 of TC93P27F 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.
