TC9322FA

The TC9322FA is a 4bit CMOS microcontroller for signal chip digital tuning systems. It is capable of functioning at a low voltage of 3V and features a built-in prescaler of operating 230MHz, PLL and LCD drivers.The CPU has Obit 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.

Features of the TC9322FA are:(1)4bit microcontroller single chip digital tuning systems; (2)features built-in 1/3-duty, 1 /2-bias LCD drivers and a built-in 3V booster circuit for the display; (3)data memory (RAM) and ports are easily backed up; (4)program memory (ROM):16bit x 3072 steps; (5)data memory (RAM):Obit x 192 words; (6)62-instruction set (all one-word instructions).The package is an pin 64, 0.5/0.65-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 1,2, OUT 1,2),there are many dedicated LCD pins, a buzzer port, a 6bit A/D converter, an IF counter, and other pins.Low-voltage and low-current consumption make this microcontroller suitable for portable DTS equipment.

The absolute maximum ratings of the TC9322FA can be summarized as:(1)supply voltage:-0.3 to 4.0 V;(2)input voltage:-0.3 to Vdd+0.3V;(3)storage temperature:-55 to 125;(4)power dissipation:100mW;(5)operating temperature:-10 to 60.The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances,etc.).These TOSHIBA products are neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunction or failure of which may cause loss of human life or bodily injury ("Unintended Usage").
