Subject: New 8-bit microprocessor
I just received the spec sheets and data book from Hitachi today on their new
HD64180 8-bit "High Integration CMOS Microprocessor". Having seen nothing on
the net about it, I thought I'd post a summary of its features and ask for
any experiences that you may have with it. If enough interest, I'll post a
summary as usual.
The HD64180-6, now available for $22.06 (1-24) supports clock speeds of up to
6 MHz. The -8 will be available 4th quarter of 1985 and support up to 10 MHz.
It comes in a 64-pin DIP with 68-pin JEDEC carrier available "later".
Features:
- Executes full Z80 instruction set with 10-20% performance improvement.
- Ten new instructions:
SLP Enter Sleep (low power standby) mode
MLT 8-bit multiply with 16-bit result
OUTO output register to immediate I/O address
INO input from immediate I/O address to register
OTIM \
OTIMR \ Block Move, Memory to I/O
OTDM /
OTDMR /
TSTIO I/O AND immediate
TST r accum AND register (non-destructive)
TST m accum AND immediate "
TST(HL) accum AND memory "
- On-chip MMU supports 512K byte memory and 64K byte I/O address space.
- Two-channel DMA controller with memory-memory, memory-I/O transfer capability.
- Two-channel full duplex asynch serial communications interface with
programmable baud rate generator and modem control signals.
- Clocked serial I/O port, operates up to 300K bps.
- Two-channel 16-bit programmable reload timer for timing and output waveforms.
- Programmable interrupt controller, 8 internal and 4 external sources.
- "E" signal to be compatible with 6800/6500 family I/O devices as well as
8080/Z80 devices.
Now if AMPRO will just make a CPM+ "Little Board" with this chip, 256/512K RAM,
floppy controller, and ST-506 controller all in one...

Obviously, any opinions expressed are my own but even I might not claim them.
I have no connection with Hitachi other than I do belong to the group that
is getting impatient waiting for the Zilog Z800...
