Product Information In-circuit serial EEPROM programmer. Special made for in-circuit serial EEPROM programming. Very useful to make car electronic programming faster and easy without soldering. In most cases short microcontroller quartz resonator or short MPU reset pin to GND.

The EPROM+ programming system is designed to support a wide variety of programmable devices from many different manufacturers. Due to the number of device manufacturers, the catagories below are organized by technology family and device pin count. The listed device numbers conform to the core numbers used by most industry standard parts. Since the individual listing of every part number from every manufacturer creates a prohibitively large list, we list all supported manufacturers in a separate table with core part numbers arranged by technology family and pin count where applicable. This approach allows you to more easily locate a device number, as many users do not know the manufacturer of the device in which they have interest. If you are uncertain about support for a specific part, please don't hesitate to contact us.

This discussion deals specifically with the Microchip 93C56 serial EEPROM. I purchased 93C56 devices from Jameco (nominally $1.00) and these are marked with the manufacturer code CGI and they appear to be like the Microchip devices. Jameco sent a data s heet from Amtel for an AT93C56 and the protocol appears to also be the same as Microchip.

In many circumstances it is desirable to work with an 8 pin serial eeprom or Motorola microcontroller while it remains connected to the circuit assembly.

WHAT IS A CORE PART NUMBER? A core part number is a number which identifies a device regardless of the manufacturer. The core number is normally easy to determine and serves as the industry standard description for nearly all common programmable devices with multiple manufacturers. The example below describes how to determine a typical core part number. Remember, a core part number usually represents hundreds of actual part numbers due to different manufacturers, speeds, temperatures, package types and other chip characteristics.

CORE PART NUMBER DETERMINATION EXAMPLE The devices on the top right are 2764 eproms from five different manufacturers. The images on the bottom right are close-up views of the first three eprom packages. The CORE part number for each device is 2764. Each 2764 has the manufacturers full part number printed on the device. The CORE part number is easily identified and has been hi-lited.

CORE part numbers are easily discerned once you exclude any prefix or suffix characters. Most devices, regardless of the technology family, can be identified by their CORE part number. PARALLEL NVRAMS AND FRAMS An NVRAM is a standard RAM ( RAM stands for Random Access Memory) which is used for general operation in computers. The NV stands for non-volatile. The RAM would normally lose its contents when power is removed, however the NVRAM is manufactured with a built in battery which keeps power applied to the memory after power has been removed from the product.

The FRAM is also a non-volatime memory component however it uses ferro-electric (magnetic) structure to store information. These parts do not have a battery and maintain their information as an array of magnetic charges. 8 PIN SERIAL EEPROMS, NVRAMS AND HI-SPEED SPI FLASH EPROMS (8 PIN) Serial EEPROMs, NVRAMS and SPI FLASH EPROMS, all 8 pin parts, offer non-volatile storage in a physically small package.
