Toshiba TC9314F Manual

TC9314F2003-07-031TOSHIBA CMOS Digital Integrated Circuit Silicon MonolithicTC9314FSingle-Chip DTS Microcontroller (DTS-22)TC9314F is a 4 bit CMOS microcontroller for single-chip digitaltuning systems with built-in prescaler, PLL and LCD driver.The CPU has 4 bit parallel addition/subtraction (eg, AI and SIinstructions), logical operations (eg, OR and AN), several bitjudge and compare instructions (eg, TM and SL), and time basefunctions.The device is in an 80 pin mini flat package. It includesabundant I/O ports controlled by powerful input and outputinstructions (IN1-3, OUT1-3) exclusive key input ports, abundantLCD output ports, interrupts, a BUZR port, 6 bit A/D and D/Aconverters, serial interface, and IF counter.With CMOS architecture for low power consumption, TC9314Fis ideal for providing digital tuning for multiband radios,radio-cessatte players and other portable equipment.Featuresx 4 bit microcontroller for single-chip digital tuning systemsx Operating voltage VDD of 2.7~5.5 V, with CMOS architecture for low power consumptionx On-chip prescaler (fixed to 1/2 frequency division +2-modulus prescaler: fmax t 130 MHz)x 1/3-duty, 1/2-bias driven LCD driver, with on-chip 3 V constant-voltage display circuitx Easy backup of data memory (RAM) and various portsx Program ROM: 16 bits × 6144 stepsx Data memory (RAM): 4 bits × 384 wordsx Powerful instruction set with 54 1-word instructionsx Instruction execution time of 40 μs (75 kHz crystal connected; 80 μs for MVGS and DAL instructions)x 4 add and 4 subtract instructionsNote 1: This device is vulnerable to surge voltage. Take it into account when using this device in your system.x Powerful compound judge instructions (TMTR, TMFR, TMT, TMF, TMTN and TMFN)x Data transfer at the same row address (MVSR instruction)x Register indirect transfer available (MVGD and MVGS instructions)x 16 powerful general registers assigned in RAMx Stack levels: 4x No concepts of pages or fields in program ROM. Features 6144 steps that allow JUMP or CAL instructions atany point.x 16 bit contents of any address in 1024 steps of the program ROM can be referenced freely. (DAL instruction)x Independent FM IN and AM IN pins for FM and AM frequency input and two phase comparison outputs (DO1and DO2).x Choice of seven reference frequencies by programx Powerful input and output instructions (IN1~3 and OUT1~3)x Input-only ports (K0~K3) for key inputs and 33 LCD drive pins (90 segments maximum).x 26 I/O ports (16 ports specifiable in units of bits, 10 output-only ports). Three pins (IF IN1, IFIN2 and DO2) canbe switched using instructions for use as input-only ports IN1 and IN2, and output-only port OT2, respectively.In addition LCD output pins S19~S30 can be switched to I/O ports in units of bits.x 2 external interrupt input ports.These are able to switch for use as general input ports by program.Weight: 1.57 g (typ.)
