INTRODUCTION
GALmate is a GAL® multi-platform programmer for electronic hobbyists. A simple RxD/TxD UART interface keeps the connection effort to a minimum. This easy-to-build circuit uses industry standard components.
HARDWARE FEATURES
- 24-pin ZIF socket
- Supported devices: GAL16V8, GAL18V10, GAL20V8, GAL20XV10, GAL20RA10, GAL22V10, GAL6001 (GAL39V18), GAL6002, ATF16V8, ATF20V8, ATF22V10, GAL26V12 & GAL26CV12 by using a simple 28-pin to 24-pin adapter
- UART interface: USB to TTL or legacy serial port
- Power: USB-powered or wall adaptor 5V DC 1A
- Vcc and Vpp are DAC controlled and current limited
- Vcc range: 3V-6V; max. 150mA
- Vpp range: 11V-18V; max. 10mA
SOFTWARE FEATURES
- Single file, easy-to-use application
- Automatic device detection, i.e. no tedious manual selection
- Fault tolerant; e.g. corrupted PES, checksum mismatch etc.
- Detection of pull-up and bus-keeper GAL features
- Fuse Map display
- ‘one click’ fuse map generation using easyABEL 4.3 for design compilation under vDosPlus
- Provides extensive device information: I/O features, UES, PES, pinout and pin by pin I/O configuration
- GALmate has been tested on Windows 10 (64-bit)
- Optional portability to Linux and OSx platforms
LET’S GET STARTED
The Basics
Starting point: I’d like to realize a (simple) logic design using a reconfigurable (programmable) logic device (PLD).
Requirements:
- PLD, e.g GAL16V8, ATF16V8, GAL22V10, ATF22V10
- HDL (Hardware Description Language) for simplified design entry (e.g. easyABEL)
- PLD Compiler (e.g. easyABEL)
- PLD Programmer (e.g. GALmate)
- JEDEC format “.jed” data file, produced by the PLD compiler
Starting point: I have the JEDEC format “.jed” data file of a logic design and I’d like to programm the data into a PLD.
Requirements:
- PLD matching the JEDEC format “.jed” data file
- PLD Programmer (e.g. GALmate)
Build up the GALmate hardware, install the software and you’re ready to go.
