MAX II CPLD breakout board [160425]
Affordable MAX II board for easy project development on standard 100 mil prototyping boards
Flash programmable Complex Programmable Logic Devices (CPLDs) are ideal for developing and/or implementing complex high-speed logic circuits.
The MAX 7000 series of Altera (nowadays: Intel) probably were the last devices in PLCC packages, which could be mounted to vero board using a PLCC socket.
Although the newer MAX II and MAX V devices are affordable, their packages are hardly suited for soldering without special equipment and their footprint doesn’t match standard 100 mil prototyping boards.
The 4-layer board we present here is designed for easy prototyping for the MAX II and it contains:
R27, R28, R29, R30, R31, R32, R33, R34, R35, R36, R37, R38, R39, R40, R41, R42, R43 = * 50 ohm, 75 V, 0603, 100 mW, ± 1% *

R20, R21, R22 = 2 kohm, 50 V, 0603, 100 mW, ± 1%,
R19*, R23, R24, R44, R45 = 10 kohm, 50 V, 0603, 100 mW, ± 1%
C2, C3, C4 = 10 µF, 25 V, ± 10%, X5R, 0805
C5, C6, C7, C8, C10, C11, C12, C13, C14, C15, C16, C17, C18 = 0.1 µF, 25 V, ± 10%, X7R, 0603
C9 = 2.2 µF, 25 V, ± 10%, X5R, 0805
IC2 = *EPM570T100C5N, CPLD, MAX II Series, FLASH, 440*
D1 = VS-10MQ040, Schottky Rectifier, 40 V, 1 A, Single
X1 = Oscillator, 40 MHz, 50 ppm, SMD, 7mm x 5mm
K3 = Pin socket, breakable, 2 rows, 12-way, vertical
K4 = Boxheader, Straight, 2.54 mm, 2 x 5 Contacts

The 4-layer board we present here is designed for easy prototyping for the MAX II and it contains:
- a 100-pin TQFP EPM570T100C5N CPLD (MAX II)
- JTAG connector for programming (e.g. with an Altera USB Blaster)
- Clock generator
- 2-row headers for connecting to your prototyping circuit
- 3.3V voltage regulator
- Power LED
- Decoupling capacitors

Also interesting was the previous Elektor FPGA expansion board, which however won't be complete without the now sadly obsolete FPGA Board. I gladly would pay the 40 euro for the FPGA Expansion Board which includes all components as kit, but it will never work without the FPGA Board being the heart of that Board's system.
Although this new project is marked as being completed, it still seems not being available? (not until next Elektor magazine May/June? after about 3 months of waiting?)
When will it be available and what does this complete FPGA board (kit?) going to cost? I think it is a good thing that it has a standard JTAG interface on-board. Working with a SD card like in the previous Elektor FPGA project was done seemed a bit troublesome.
Thanks.
