TC9327BFG

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9327BFG TC9327BFG 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-instru...
