General Description
H400 Features
·Hitachi has a range of devices offering flexibility in I/O with both high and low voltage drive capability, LCD drive, timers, serial communications, RAM, ROM and a large range of other peripherals. All members are produced using HitachiÕs high performance CMOS process for high speed with low power, further reduced by SUBACTIVE, STANDBY, WATCH and STOP low power operating modes.
·The family ranges from the very cost efficient HD404341 via the HD404654 with 1.8V operation to the highly integrated HD404629. With operating voltage ranges of Vcc=(1.8-6.0)V for the Mask ROM/ZTAT devices (HD404889/HD4074889), these devices are clearly suited for use in low voltage/low power applications.
·The H400 series has an architecture ideal for controllers in which bit I/O and status flag processing in software are important.
- Highly efficient 10bit wide ROM making 80% of instructions single cycle and single word.
- Direct addressing to both ROM and RAM.
- Bit manipulation for both RAM and I/O.
- Direct branch to all ROM areas.
- Binary or BCD Arithmetic operation.
- Powerful Logical Arithmetic operation.
- Pattern Generation - look-up table capability For example, the HD40A4689 has in total 101 instructions, of which ·75% are single cycle instructions and 23% are two cycle instructions.
Cycle times down to t=0.47ms combined with the efficient code, results in a device ideal for control applications.
·There are three RAM and four ROM addressing modes. RAM
- Indirect register addressing
- Direct addressing
- Memory register addressing ROM
- Direct addressing
- Current page addressing
- Zero page addressing
- Table data addressing
·The H400 processor core consists of an accumulator, B, V, W, X, Y, SPX, SPY registers, Carry and Status bit, as well as a Stack Pointer register.
