HCS_C PC board feature list (subject to change):
(Version 1.2 (1/31/04 )
a: ARM AT91R40008 processor operating at 29.4910Mhz
b: JTAG ARM emulation interface
c: JTAG FPGA Eprom programming interface
b: AM29DL323DB flash EPROM (x4)
c: KM616V4002-15 SRAM (x2 with two extra chipselects for stacking for a total of 2Mbytes)
d: Altera 20K100-1 240 PQFP (currently about 80% full)
e: 32 buffered and protected inputs (RC plus diodes)
f: 32 buffered and protected outputs (RC plus diodes)
g: Voice chip (WinBond 4003-08MP) (can be doublestacked)
h: Powerful onboard state analyzer operates independently from the processor for tracking even if the processor goes into the weeds
i: Automatic vectoring interrupt controller for up to 270 interrupt sources
h: Epson RTC-4543A Real Time Clock'
k: Firmware interval/minimum/maximum recording timer resolution in .54us
i: RS485 interface (x3) Three stage receive FIFO, three stage transmit buffer.
j: RS232 interface (x2) Note to save board space, I changed the RS232 connector from a 16 pin connector to an 8 pin connector, so you'll have to make a new RS232 cable connector--sorry! Most of the pins on the old connector were not used. Three stage receive FIFO, three stage transmit buffer.
k: Seetron LCD display serial port interface
l. 16 bit SPI interface (intended for Canon Vulcan LCD touchscreen display).
l: PS2 keyboard interface
m: HCS2 compatible daughtercard stack with 4 programmable card selects and interrupts for each card and 16 address lines rather than 8. Note that this interface is only 8 bits data, though. NOTE (1/31/04) As of A.03, HCS_C WILL NOT SUPPORT LEGACY HCS2 BOARDS (TOO MUCH DANGER OF DAMAGE DUE TO DIFFERENT POWER SUPPLY VOLTAGES)
n: Relay driver interface and relays (x2)
o: CID serial port
m: X10 Serial interface is now on the FPGA. If this works, it will replace the PLIX X10 board--it's looking much better than PLIX at this point. It is fully automatic with minimum programming attention. Four stage receive FIFO.
n: Hard reset, four configuration (boot control) DIP switches, and four status LEDs
m: The board is all +3V, but +5V goes to the daughtercard bus, the Seetron LCD display, the PS2 keyboard, and a few other places. I would assume the board is going to consume about 500-1000mA.
Features you want to see on this board? It's getting late, the board is approaching completion. But if you see something good to put on that I missed, send me an Email
