#SPI EPROM PROGRAMMER HOW TO#

Performing a memory read operation with the Aardvark adapter requires a single command from the adapter and Control Center. Then the 24FC512 Sequential Read operation performs I2C read with 7 bit device address, two or more bytes of memory data, and stop. The 24FC512 Sequential Read operation first performs I2C write with 7 bit device address, two byte memory address and no stop. The 24FC512 read operation used here is the Sequential Read. In this case, the Control Center 'Master Write' command includes the device address (0x50), memory address (0x0008), and memory data (0x0A 0x0B 0x0C). Performing a memory write operation with the Aardvark adapter requires a single command from the adapter and Control Center. The Page Write operation to the 24FC512 requires 7 bit device address, two byte memory address, and two or more bytes of memory data. The 24FC512 write operation used here is Page Write. For additional information take a look at the EEPROM socket board user manual.

In order to supply the I2C pull-ups and target power to the I2C EEPROM on the EEPROM socket board, the Aardvark adapter should be configured to I2C pull-ups enabled and target power enabled. The I2C EEPROM on the EEPROM socket board receives the I2C pulls-ups and power from the Aardvark adapter. For additional information take a look at Figure 2: 24FC512 Control Byte Format and knowledge base article 7-bit, 8-bit, and 10-bit I2C Slave Addressing. This article uses the default I2C target address 0x50. The default I2C target address is 1010000b, which is 0x50. The 24FC512 I2C EEPROM on the EEPROM socket board has a hardware configurable I2C target address. For additional information take a look at Figure 1: Aardvark and 24FC512 Block Diagram, level shifter board user manual, and EEPROM socket board user manual.ДЇigure 1: Aardvark and 24FC512 Block Diagram The level shifter board converts the Aardvark 3.3V I2C signals and 5V VDD signal to 1.8V I2C signals and 1.8V VDD signal. The Aardvark is connected to the 24FC512 1.8V SOIC-8 inВ the EEPROM socket board through the level shiter board.

In this article the Aardvark adapter is the I2C master and the I2C EEPROM 24FC512 inВ the EEPROM socket board is the I2C slave.

The goal of this article is to demonstrate how to write several bytes to a specific address and then read back those bytes. Although the following describes the Microchip 24FC512 I2C EEPROM with the EEPROM Socket Board, similar steps can be used for other devices. This article also shows how to use the level shifter board in order to supply low voltage level to the I2C EEPROM. This article focuses on how to take the information in an EEPROM datasheet and execute the commands in Control Center. There are several ways to do this with the Aardvark adapter, including using Control Center, Flash Center, or the Aardvark API. Programming I2C memory devices is a common use case for the Aardvark I2C/SPI Host Adapter and level shifter board.
