Arduino, 23K256 SRAM and 74LVC245 Bus Transceiver

As discussed in this post, when interfacing 3.3V devices with a 5V Arduino, the logic level needs to be shifted. Most 3.3V devices will be damaged if operated with 5V signals, while others will simply operate unreliably. The shifting can … Continue reading

Microchip 23K256/Arduino Transfer Rates

I used my Saleae Logic to time the transfer (read/write) rates between the Arduino and Microchip 23k256 SPI SRAM. See this post for more information on the Arduino and 23K256. Here is the program that was running on the Arduino: … Continue reading

Interfacing Microchip 23K256 32KB SRAM SPI Memory with Arduino

My GPS Predictive Lap Timer Project needs more memory than the typical Arduino contains. However, it occurred to me that I could use a Microchip 23K256 32KB SRAM SPI memory chip and not need to revert to an Arduino Mega … Continue reading
