HMCS404C (HD614042) AUTOMOTIVE Ld HMCS404CL (HD614045) Mai HMCS404AC (HD614048) 4-BitCMOS Microcomputers The HMCS404C/CL/AC are CMOS 4-bit single-chip micro- TIMCSADAC, HMGS404CL, HMCS404AC computers which are members of the HMCS400 series ‘The HMCS404C/CL/AC have efficient and powerful architec- ture and its software is very similar to the HMCS40 series. These microcomputers provide variety of on-chip resources such as ROM, RAM, 1/O, two timer/counters and a serial interface to perform in wide users’ applications. 1/0 pins of HMCSA04C/CL/AC are able to drive fluorescent display tube directly The HMCS404CL is able to operate in low voltage and has the characteristics of wide-range operation voltage ‘The HMCS404AC is a high-speed version of HMCS404C. © HARDWARE FEATURES © 4bit Architecture © 4,096 Words x 10-bit ROM © 256 Digits x 4-bit RAM {DP-64S) © 58 1/0 Pins, Including 26 High Voltage 1/0 Pins (40V Max) © Two Timer/Counters HMCS404C, HMCS404CL, HMCS404AC 11-bit Prescaler B-bit Free Running Timer B-bit Auto-Reload Timer/Event Counter © Clock Synchronous 8-bit Serial Interface © Five Interrupts External 2 Timer/Counter 2 Serial Interface 1 ‘© Subroutine Stack 2 Up to 16 Levels Including Interrupt * © Two Low Power Dissipation Modes ‘Standby Stops instruction execution while keeping (FP-64) clock oscillation and interrupt functions in operation Stop — Stops instruction execution and clock oscil- lation while retaining RAM data © On-Chip Oscillator © VERSATILE PROGRAM DEVELOPMENT SUPPORT External Connection of Crystal, Ceramic Filter or Re TOOLS {externally drivable) @ H68SD Series Macro Assembler (Resistor oscillator is available only to the HMCS404., © HEBSD5A-use Emulator (With Real Time Trace Function) © EPROM On Package Microcomputer; HD614PO80S = SOFTWARE FEATURES Mask options are fixed as follows: © Instruction Set Similar to and More Powerful than HMCS40 @ WO pin: Open Drain Series; 99 Instructions © Oscillator : Crystal Oscillator or Ceramic Fitter Oscillator @ High Programming Efficiency with 10-bit ROM/Word; 79 .
