I have a Western Telematics, Inc RPB+ remote power strip.
On the outside:
- 5 switched AC outlets, individually controllable
- Can switch up to 15A on one port, up to 15A for all ports.
- 9 pin RS232 port (you need a null modem cable to connect)
- Dip switch for setting baud rate
- An LED for each outlet on the front panel
Inside it has:
- a PIC 16C56 microcontroller, in a socket
- 5 nice relays and associated drivers to interface to PIX
- a 555 timer
- an ADM232 on the serial port
- a power supply
A PIC 16C56 has:
- 18 pin DIP
- 1.5K memory
- 25 bytes of RAM (whew! takes my breath away!)
- 1 8-bit timer
- It's OTP = one time programmable
To substitute a flash device I could drop in a 16F628A, then I'd get 3.5k of RAM and 224 bytes of RAM.
