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 5V ‹ Internal Program ROM: 2K x 10-bit ‹ 1 sets of 14-bit DPR can access up to 16K x 10 bits data memory space ‹ Data Registers: • 48 x 4-bit data RAM (00-1Fh plus 40h-4Fh) • Unbanked special function registers (SFR) range: 20h-3Fh ‹ I/O Ports: • PRA: 2-bit I/O Port A (2Bh) ‹ 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 ASMxxxxx 1 Rev 1.0 ASM0402C FIGURE 1.1 : Block Diagram of ASM0402C Data Bus[3:0] ROM Latch PCL(4) PC[11:0] (ADDR[13:12]) =00b ADDR[13:0] Stack(12) (2-Level) 0 ROM_ADDR[13:0] 1 DPR3,2,1 DPR[13:0] Program (Data) ROM Instruction Latch Instruction Bus [9:0] Instruction Decoder PCLATCH(8) PCH(8) DLATCH(10) ROM_Data[9:0] Data Bus[3:0] Accumlator(4) Instruction Bus [9:0] SRAM ALU(4) Register(4) Immediate(4) (48 x 4) 00h-1Fh 40h-4Fh Timer0(9) PRA(2) weak or strong pull-low for PRA P1,P2,P3,P4 enter test mode ( Voice synthesizer ) Clock Generator Test select Power on Reset RESET pin PRA0 OSC VDD/GND PRASL(2) One-Channel Reset Chip Reset Chip COUT COUT 2 Rev 1.0 Instruction Bus [9:0] Control Signal ASM0402C FIGURE 1.2 : External ROM Map of ASM0402C PC[11:0] 12bit x 2 STACK 14-bit Data Pointer Reset Vector 00000h 00080h Reserved for Testing Program and data ROM 00080h-003FFh 00400h 00000h-007FFh 00000h-03FFFh 007FFh(2K) Data ROM 03FFFh(16Kx10-bits) 3 Rev 1.0 ASM0402C 1.2 Pin-Out ASM0402C Pin-Out VDD PRA1 PRA0/RESET I I/O I/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.
