A13-SOM-512

Overview

The A13-SOM-512 is a System-on-Module manufactured by Olimex Ltd., designed for embedded computing applications. It integrates the Allwinner A13 processor, which features an ARM Cortex-A8 core operating at a frequency of 1 GHz. The module includes 512 MB of DDR3 RAM and 4 GB of NAND flash memory for data storage. It operates within a temperature range of 0°C to +70°C and requires a 5 V power supply. The physical dimensions are 55.88 mm x 36.83 mm. Key interfaces exposed include GPIO, I2C, SPI, UART, USB, and SDIO, facilitating connectivity with peripheral devices and sensors in industrial or consumer electronics projects.

Feature Summary

Procurement Notes

Verify the specific revision level and firmware pre-installation status when ordering, as Olimex may update hardware revisions without changing the base model number. Confirm RoHS compliance documentation is included with the shipment. Check current distributor stock levels as availability for legacy ARM9/ARM7 based modules can fluctuate. Ensure the carrier board design matches the pinout specifications provided in the official schematic.

Selection Notes

Select the A13-SOM-512 when a balance of moderate processing power and low cost is required for Linux-based embedded tasks. Compare against the A13-SOM-256 if only 256 MB of RAM is sufficient for the application, which may reduce costs. Consider the RK3328-SOM series if higher performance or newer architecture support is needed. Verify that the 5 V input voltage aligns with the system power design, as other Olimex SOMs may accept wider voltage ranges.

Part Context

This module belongs to Olimex's A13 System-on-Module family, which utilizes the Allwinner A13 SoC. It is often paired with evaluation boards such as the A13-OLinuXino-LIME or custom carrier designs. The product line targets developers needing an open-source hardware solution for prototyping and small-batch production. It serves as a drop-in replacement for older single-board computers in space-constrained enclosures.

Replacement Considerations

Direct pin-compatible replacements are limited due to the specific Allwinner A13 footprint. For functional upgrades, consider the RK3328-SOM-1G or RK3328-SOM-4G for improved CPU performance and modern interface support. If lower power consumption is critical, evaluate STM32MP157-based SOMs, though these require significant software adaptation due to different architectures.
