Parallel Eeprom Programmer, The address bus of the EEPROM (up to 15 bit) is controlled via two daisy-chained 74HC595 shift registers using hardware SPI @ 8 Mbps. China PCB Prototype & Fabrication Manufacturer - PCB message error Dec 5, 2007 · Hi Read through this forum for many months, to get supplement to my class studies. Address and data bus are Apr 30, 2013 · For my upcoming 6502 CPU based homebrew computer project I need the possibility to program EPROMs and EEPROMs. Notes The AT28C16 is an old-school 2k x 8-bit parallel EEPROM. Universal Programmer for parallel EEPROMS using a python CLI and a simple Arduino with 2 shift-registers to interface the EEPROM. This guide reviews the 100% CH554T XP866, a high-speed USB SPI programmer that supports multiple EEPROM and Flash chip models. You can buy a programmer, but they are too expensive for just a simple project. Jul 29, 2018 · Parallel NOR Flash / EEPROM Programmer using an Arduino – Part 1 (The SST39SF040 and Planning) mikemint64 Electronics Jul 29, 2018 5 Minutes Jun 13, 2019 · Using the Arduino Platform and basic coding, we can show how it possible to store data on a EEPROM memory chip with the parallel bus interface. Additionally some control lines like /WRITE, /OUTPUT and /ENABLE need to be connected to the EEPROMs. ino) implements an EEPROM Parallel EEPROM/Flash Programmer for many different devices, featuring: GUI-based front-end written in Python Ability to program memories up to 1 MB in size with the current pin configuration, theoretically up to 4 GB possible (although good luck with the 500 Kbps transfer rate) Support for programing devices with 1-byte pages all the way up to devices with 4096-byte pages Possibility to Oct 23, 2019 · I built an EEPROM programmer and a ROM board for my Amstrad 464 in the mid-'80s.
