TC9323F

The TC9323F is a 4-bit CMOS microcontroller for single-chip digital tuning systems, containing prescalers operating at frequencies up to 150MHz, a PLL, and an LCD driver.The  TC9323F CPU provides 4-bit parallel addition and subtraction instructions (such as AI and SI), logic operation instructions (such as OR and AN), and multi-bit judgment and comparison instructions (such as TM and SL), plus timebase functions.The package is an 80-pin miniflat package, with a large number of I/O ports and key input ports that are controlled by a powerful I/O instructions(1N1 to 3, OUT1 to 3).

Features of the TC9323F are:(1)numerous addition and subtraction instructions (4 different addition instructions and another 4 different subtraction instructions); (2)powerful complex decision instructions (TMTR, TMFR, TMT,TMF, TMTN, TMFN); (3)instruction for transmitting data between addresses on the same row address (MVSR); (4)register-to-register indirect transfer instructions (MVGD,MVGS); (5)16 powerful general registers (located in RAM); (6)stack level:8; (7)program memory (ROM) free from page and field concepts, allowing unrestricted branches within 12,288 steps (JUMP instruction); (8)free reference to the 16-bit contents of any address in 1,024 steps in program memory (ROM); (9)built-in 20-bit general-purpose IF counter, counting intermediate frequencies over each band to detect broadcasting stations during auto-tuning.Other numerous features that recommend the TC9323F for use digital tuning systems include interrupt handling facilities, a buzzer, 6-bit A/D and D/A converters, a serial interface, and an IF counter.

The absolute maximum ratings of the TC9323F can be summarized as:(1)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").
