More info

CPLD development board designed for ALTERA MAX II series, features the EPM1270 onboard, and integrates various standard interfaces, pretty easy for peripheral expansions.

Overview

OpenEPM1270 is a CPLD development board that features the EPM1270 device onboard. It supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with ALTERA MAX II series CPLD devices.

What's On Board

EPM1270 development board on board resource

- Operating Voltage: 1.5-3.3V
- Package: QFP144
- I/Os:116
- LEs: 1,270, the equivalent to 4,000 logic gates
- Debugging/Programming: JTAG
AMS1117-3.3: 3.3V voltage regulator
Power switch
Power indicator
LEDs: convenient for indicating I/O status and/or program running state
Joystick: five positions
Reset button
Buzzer
8 I/Os interface: for connecting accessory boards
16 I/Os interface: for connecting accessory boards
8 I/Os interface: for connecting accessory boards
32 I/Os interface: for connecting accessory boards

For interface 9-12: it's possible to emulate the interfaces as ONE-WIRE, USART, I2C, SPI, PS/2, etc.

1-WIRE interface: for connecting 1-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
Character LCD interface: for connecting character LCD, such as the LCD1602 (5V Blue Backlight) in Package B
5V DC jack
JTAG interface: for programming/debugging
MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion
LEDs jumper
Buzzer jumper

For jumper 18-19:

short the jumper to connect to I/Os used in example code
open the jumper to connect to other custom pins via jumper wires
