Touch Keypad - This board layout was created using the SOIC version of a
PIC16F627A without drawing the usual schematic first. Most of the part values
are etched on the Layout. The SIP resistor packs I used are 10k ohm, some
experimentation with this value may be useful....(circuit added 08/08/08) [Luhan Monat

Two chips simplify layout for high-end embedded control - 04/01/99 Issue of
EDN If you are considering using one of the 32- or 64-bit RISC µPs from
Integrated Device Technology (IDT], the company’s new RC32134 and RC64145
system-controller ICs (Picture] can make your job easier. The chips provide
synchronous-DRAM, memory, and I/O control; a PCI interface; and peripherals, including
UARTs, timers, and interrupt controllers. The 32134 for the RC32364 µP provides a
glueless interface to DRAM....Page includes several designs. Scroll to find this
one....[Design Idea by Graham Prophet] |

Two DDS ICs implement amplitude shift keying - 25-Dec-03 Issue of EDN
Many communications systems, including RFID systems and cable modems, use AM
(amplitude modulation]. This Design Idea shows how two DDS
(direct-digital-synthesis] devices can implement AM and ASK (amplitude-shift keying]
over a range of frequencies. The AD9834 complete 50-MHz DDS IC (Figure 1] has a
current output, so you can easily sum the outputs of two orof them by connecting them
to a....[Design Idea by Noel McNamara, Analog Devices, Limerick, Ireland] |
