It has various features including 4-bit ALU, ROM, RAM, I/O ports, timers, clock generator, watchdog timer(WDT), voice synthesizer, etc. It consists of 22 instructions in the device. With CMOS technology and halt function can minimize power dissipation. Its architecture is similar to RISC, with two stages of instruction pipeline. It allows all instructions to be executed in a single cycle, except for program branches and data table read instructions (which need two instruction cycles). 1.1 Feature Single power supply can operate from 2.4V through 5.5V Internal Program ROM: 4K x 10-bit 1 sets of 18-bit DPR can access up to 192K x 10 bits data memory space Data Registers: • 64 x 4-bit data RAM (00-1Fh plus 40h-5Fh) • Unbanked special function registers (SFR) range: 20h-3Fh I/O Ports: • PRA: 4-bit I/O Port A (2Bh) • PRB: 2-bit Output Port B (2Dh) On-chip clock generator: Resistive Clock Drive(RM) Timer: 1 • Timer0: a 9-bit auto-reload timer/counter Stack: 2-level subroutine nesting HALT and Release from HALT function to reduce power consumption Watch Dog Timer (WDT) Instruction: 1-cycle instruction except for table read and program branches which are 2-cycles Number of instruction: 22 The Voice function can be implemented by microprocessor instruction • One 8-bit COUT output for ASM5206C/6306C 1 Rev 1.0 ASM5206C/6306C FIGURE 1.1 : Block Diagram of ASM5206C/6306C Data Bus[3:0] ROM Latch PCLATCH(8) PCL(4) Stack(12) PC[11:0] (ADDR[17:12]) =00000b (2-Level) ADDR[17:0] Instruction Bus [9:0] 1 DPR3,2,1 Instruction Latch 0 ROM_ADDR[17:0] Program (Data) ROM DPR[17:0] Instruction Decoder Control Signal DLATCH(10) ROM_Data[9:0] Data Bus[3:0] Instruction Bus [9:0] Accumlator(4) SRAM ALU(4) Immediate(4) PRA(4) PRB(2) Timer0(9) (64 x 4) Instruction Bus [9:0] PCH(8) 00h-1Fh 40h-5Fh Register(4) enter test mode One-Channel ( Voice synthesizer ) Reset Chip Reset Chip Clock Generator PRASL(4) VDD/GND Power on Reset RESET pin COUT OSC Test select PRA0 P1,P2,P3,P4 weak or strong pull-low for PRA, PRB, PRC COUT 2 Rev 1.0 ASM5206C/6306C FIGURE 1.2 : External ROM Map of ASM5206C/6306C PC[11:0] 12bit x 2 STACK 17-bit Data Pointer Reset Vector 00000h 00080h Reserved for Testing 00080h-003FFh 00400h Program and data ROM 00000h-00FFFh 00FFFh(4K) Data ROM 00000h-2FFFFh 2FFFFh(192Kx10-bits) 3 Rev 1.0 ASM5206C/6306C 1.2 Pin-Out ASM5206C/6306C Pin-Out VDD PRA3-1 I I/O PRA0/RESET I/O OSC COUT GND TEST PRB0-1 I O I O O Power supply during operation STI I/O port with programmable strong pull-low or weak pull-low or fix-inputStd./O.D. floating capability Output type with standard or Open-Drain output STI I/O port with programmable strong pull-low or weak pull-low or fix-inputStd./O.D. floating capability Output type with standard or Open-Drain output Mask option selected as an external RESET pin with weak pull-low capability RM mode Oscillator input Current Output of Audio Circuit Ground Potential Enter Test Mode.
