EEPROM Programming Instructions

Application Note

Introduction

The 8A3xxxx Family of products from IDT are designed to power-up and operate using internal resources.

However there may be cases where it is necessary or convenient to make use of an external I2C serial EEPROM

for the device to obtain alternate information from at reset.

This document provides information about the EEPROM hardware connections, how to program the EEPROM

using the Clock Matrix chip, and other miscellaneous information.

1. EEPROM Overview

The ClockMatrix 8A3xxxx product family from Renesas is designed to power-up and operate using internal

resources. However, there may be cases where it is necessary or convenient to use an external I2C serial

EEPROM for the device in order to obtain alternate information at reset.

The external EEPROM can be used to contain one or more of the following:

• Device configuration information block (Config)

• Micro-controller Firmware Full Application Load (FW Application)

• Micro-controller Firmware Patch (FW Hotfix)

These blocks may appear in any order in the EEPROM, but only one FW Application or one FW Hotfix will be

applied. A FW Hotfix may not be applied to a FW Application block loaded from EEPROM; only to the internal

(embedded) firmware. Any number of Config blocks are allowed.

Renesas will provide the EEPROM image in the form of a .hex file that is formatted according to the Intel Hex

format. Details of the structure of the EEPROM is beyond the scope of this document.

The following instructions describe the hardware connections for the EEPROM, how to program the EEPROM

using the Clock Matrix chip, and other miscellaneous information.

2. Hardware Setup

The following is an example setup schematic.

Figure 1. EEPROM Circuit

Connect the SCLK and SDA traces to the ClockMatrix device master I2C port (SCLK and SDA). Another

recommendation is to also place a 3-pin header that connects to the EEPROM SCLK, SDA, and GND pin (see

green outline in Figure 1). Using this method, an external programmer can be connected to the system for

programming. Be aware that external programmers may only support 3.3V levels, so if the VCC_GPIO on the

chip is 1.8V or 2.5V a level translator is required.

In the case of prototype boards, a PDIP socket, such as the DILV8P-223TLF can be used (see Figure 2). This

allows for easy removal of the EEPROM so that it can be programmed using an external board, such as the Total

Phase EEPROM Socket Board.

Figure 2. PDIP Socket

3. Programming the EEPROM

There are three options for programming the EEPROM:

• External EEPROM flash card

• Header

• Clock Matrix chip

3.1 External Flash Card Option

For this option, use the PDIP socket. Use the Total Phase EEPROM socket board to program the EEPROM and

then place the EEPROM into the socket. For more information, see Programming the 8A3x000 EEPROM with

Total Phase. Alternatively, another vendor's EEPROM flash card can be used.

3.2 Header Option

For this option, the EEPROM is installed in the system board and an accompanying 3-pin header is used as

described in Programming the 8A3x000 EEPROM with Total Phase. However, connect the Total Phase Aardvark

card directly to the 3-pin header and use the Total Phase software to program the EEPROM.

3.3 Clock Matrix Option

For this option, the ClockMatrix chip serves as the intermediary, transferring the data from the System Device to

the EEPROM, as shown in Figure 3. Either a CPU, an FPGA, or a different System device will “talk” to the

ClockMatrix device through the Main or Auxiliary Serial port and send it the firmware data. In turn, the ClockMatrix

device will send the data to the EEPROM chip. Note that it is the customer's responsibility to parse the .hex file

into a format that is usable by their system.

Figure 3. Programming the EEPROM through Clock Matrix

The ClockMatrix device contains a register buffer that functions as an EEPROM read/write buffer. Access to the

buffer is obtained using the following registers. For register offset values, see the 8A3xxxx Family Programming

Guide that corresponds to the firmware present in the ROM.

The EEPROM buffer register is 128 bytes long, and is the location where the data is either written to the EEPROM

or read from the EEPROM. For PR4.0, the location is 0xCF80.

The following is an example of an SPI 2-byte addressing sequence that shows how to program the first 128 bytes

of an EEPROM. This example is based on PR4.0 Firmware. For a different firmware, see the appropriate 8A3xxxx

Family Programming Guide.

3.4 Write EEPROM Example

7F FD 80 10 20 #Set the Clock Matrix page register (SPI 2-byte addressing)

4F 68 50 #Write to CF68, set EEPROM_I2C_ADDR=0x50

4F 69 80 #Write to CF69, set EEPROM_SIZE=128 bytes.

4F 6A 00 00 #Write to CF6A, set EEPROM_OFFSET= 0 (write starting at location 0).

4F 80 85 AA 85 AA 84 AA 84 AA 83 AA 83 AA 82 AA 82 AA 81 AA 81 AA 80 AA 80 AA 79 AA 79 AA

78 AA 78 AA 77 AA 77 AA 76 AA 76 AA 75 AA 75 AA 74 AA 74 AA 73 AA 73 AA 72 AA 72 AA 71 AA

71 AA 70 AA 70 AA 69 AA 69 AA 68 AA 68 AA 67 AA 67 AA 66 AA 66 AA 65 AA 65 AA 64 AA 64 AA

63 AA 63 AA 62 AA 62 AA 61 AA 61 AA 60 AA 60 AA 59 AA 59 AA 58 AA 58 AA 57 AA 57 AA 56 AA

56 AA 55 AA 55 AA 00 00 00 00

#Write to CF80, these are the 128 bytes that will be written to the EEPROM.

4F 6C 02 EE #Write to CF6C, EEPROM_CMD="0xEE02", trigger EEPROM write

#add a wait time to allow the chip to write to the EEPROM. For now, use 100mS. Alternatively, read back the

EEPROM_STATUS and verify that it is 0x8000 and then proceed.

Repeat this for each 128 bytes of EEPROM data.

3.5 Read EEPROM Example

4F 6A 00 00 #Write to CF6A, set offset

4F 6C 01 EE #Write to CF6C, trigger EEPROM read

#add a wait time to allow the chip to write to the EEPROM. For now, use 100mS.

7F FD 80 10 20 #Set page register

#Read from CF80, read back buffer (note that MSB is set for read commands)

CF 80 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
