TC9304F

The TC9304F is 4bit CMOS microcontroller with built-in prescaler, PLL, LCD driver for single-chip digital tuning system.CPU has Obit parallel addition and subtraction (AI/SI instructions), logical operation (OR and AN instructions), plural bit judge, comparission instructions (TM, SL instructions) and time base function.The package of TC9304F is of 60-pin mini-flat type, and is provided with the abundant I/O ports and exclusive key-input ports controlled by the powerful input/output instructions(IO,KEY instructions) and with the abundant exclusive LCD output terminals of 1/2 duty and 1/2  bias drive.

Features of the TC9304F are:(1)4bit microcontroller for single-chip digital tuning system; (2)5V±10% single power supply. CMOS structure with low power dissipation; (3)built-in prescaler (at FM, max. 140MHz direct input), PLL and LCD driver (1/2 duty, 1/2 bias driving freq uency:50Hz); (4)backup of data memory (RAM) and of various kinds of ports is easy (with Vpp2 terminal); (5)program memory (ROM):16 bits x 1024 steps; (6)data memory (RAM):4 bits x 128 words; (7)62 kinds of powerful instruction sets (all are single-word instructions).2 modulus prescaler, PLL circuit and IF counter for generating the auto-stop signal through counting IF at each band of FM or AM are incorporated. In addition, the serial bus control function(SIO instruction) for powerfully controlling the peripheral IC and the Obit A/D converter applicable to the measurement of the electric field intensity through inputting the signal meter output are incorporated resulting in making many functions necessary for the digital tuning system provided.

The absolute maximum ratings of the TC9304F can be summarized as:(1)power supply voltage:-0.3 to 6.0 V;(2)input voltage:-0.3 to Vdd+0.3V;(3)storage temperature:-65 to 150;(4)power dissipation:400mW;(5)operating temperature:-40 to 85.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").
