Introduction[edit | edit source]
The heart of AXEL ULite system-on-module (SOM for short) is composed by the following components:
- NXP i.MX6UL application processor
- Power supply unit
- DDR3L memory bank
- NOR and NAND flash banks
- 1x 204 pin SODIMM connector with interfaces signals
This article shortly describes the main AXEL ULite components.
Processor Info[edit | edit source]
The i.MX 6UltraLite (i.MX6UL) processor features NXP’s advanced implementation of the ARM® Cortex®-A7, a single-core cost-effective and power-efficient solution, which operates at speeds up to 696 MHz. This SOC includes a deep encryption and security capability, a complex and flexible boot management and an integrated power management. As a result, i.MX6UL devices are able to serve a wide range of applications including:
- Industrial/IoT gateways
- Instrument clusters, and portable medical devices
- Dataloggers
- Remote control units
- Human-machine interfaces
- Safety blocks for IoT data manipulation and streaming
The i.MX6UL application processor is composed of the following major functional blocks:
- Single ARM Cortex-A7 MPCore, featuring:
- 128KB unified L2 cache
- NEON MPE coprocessor
- External memories interconnect
- Connectivity peripherals, including
- 2xRMII - Ethernet 10/100 interfaces
- SD/SDIO/MMC
- Serial buses: USB, UART, I²C, SPI, CAN, ...
- Security Module, including:
- True and Pseudo Random Number Generator
- Cryptographic Acceleration and Assurance Module
- Secure Non-Volatile Storage with Violation/Tamper detection and reporting
AXEL ULite can equip the entire range of i.MX6UL SOC models with the following main features:
- Package: 14 x 14 mm, 0.8 pitch, BGA
- Clock frequency: 528 MHz or 696 MHz
- Commercial (0-95°C), Industrial (-40-105°C) and Automotive (-40-125°C) temperature ranges
RAM memory bank[edit | edit source]
DDR3L SDRAM memory bank is composed by a 16-bit wide chip. The following table reports the SDRAM specifications:
| CPU connection | Multi-mode DDR controller (MMDC) |
| Size min | 256 MB |
| Size max | 512 MB |
| Width | 16 bit |
| Speed | 400 MHz |
NOR flash bank[edit | edit source]
NOR flash is a Serial Peripheral Interface (SPI) device. This device is connected to the ECSPI1 channel 5 and can act as boot memory. The following table reports the NOR flash specifications:
| CPU connection | ECSPI1 |
| Size min | 8 MB |
| Size max | 32 MB |
| Chip select | ECSPI1_SS0 |
| Bootable | Yes |
NAND flash bank[edit | edit source]
On board main storage memory is a 8-bit wide NAND flash connected to the CPU's Raw NAND flash controller. Optionally, it can act as boot peripheral. The following table reports the NAND flash specifications:
| CPU connection | Raw NAND flash controller |
| Page size | 512 byte, 2 kbyte or 4 kbyte |
| Size min | 128 MB |
| Size max | 2 GB |
| Width | 8 bit |
| Chip select | NANDF_CS0 |
| Interface | asynchronous |
| technology | SLC |
| Bootable | Yes |
Power supply unit[edit | edit source]
AXEL ULite embeds all the elements required for powering the unit, therefore power sequencing is self-contained and simplified. Nevertheless, power must be provided from carrier board, and therefore users should be aware of the voltage ranges power supply can assume as well as all other parameters. Three supported voltage ranges are available. For more details please refer to this page.
Bootstrap options[edit | edit source]
For more details about bootstrap options, please refer to this page.
SOM connector[edit | edit source]
All interface signals AXEL ULite provides are routed through SODIMM DDR3 204 pin. The dedicated carrier board must mount the counterpart mating connector and connect the desired peripheral interfaces according to AXEL ULite pinout specifications.
