HaneSOM
Small Embedded System on Module
Overview
The HaneSOM – small embedded compute module.
The HaneSOM board is based on ARM® Cortex®-AS processor-based SAMA5D2 MPU with up to 1 Gbit DDR2-SDRAM in a single package and 32 Mbit of QSPI Flash. This makes HaneSOM module suitable for small device integration.

Power supply.
| Pin | Description |
| 18,19 | +3.3V power tine |
| 17, 34, 37, 40, 55, 82 |
GND |
| 33 | SDMMCO power supply (1.8V or 3.3V) |
| 28 | RTC power supply |
| 83 | Camera ISC pins power (1.65 .. 3.6V) |
• Using order code “DAB-002002” – module supplies with 0 Ohm resistors connects 83, 28, 33, 18, and 19 pins all together – for single 3.3V operation.
Power consumption example:
| Condition | Time of active operation |
| Linux 5.4 running, IDLE | 3.3V ci 160mA |
| ULPO | TBD |
| ULP1 | TBD |

Details
Package and pinout
The handsome is using SAMASD2 SIP in the TFBGA289 package.
More details in Microchip DS60001484A datasheet: “SAMASD2 System-In-Package (SIP) MPU with up to 1Gbit DDR2 SDRAM”.
Memory
The HaneSOM module has a Winbond W971GG6SB DDR2 chip integrated into the same SAMASD2 SIP.
Additionally, QSPI Flash GigaDevice GD2SQ32CNIGR has been installed onboard. The QSPI Flash connected to QSPI1 port, I0Set 2:
| Signal | Pin |
| QSPI1_SCK | PBS |
| QSPI1_CS | PB6 |
| QSPI1_100 | PB7 |
| QSPI1_IO1 | PB8 |
| QSPI1_102 | PB9 |
| QSPI1_103 | PB10 |
Booting from QSPI Flash can be disabled, by pushing pin 86 of the HaneSOM to low level (GND).
Power supplies
The HaneSOM is supplied by an external 3.3V and generates all necessary voltages using PMIC Microchip MIC2800. PMIC generates DDR2 voltage (1.8V), core power line (1.25V), and VDDFUSE (2.5V).
IMPORTANT: The HaneSOM has internal resistors R8-R10 which connect VDDSDHC, VDDISC, and VDDBU to 3.3V. If the customer requires to supply separate power lines with different voltage levels, needs to order the HaneSOM module with “-NS” postfix.
System control
The HaneSOM provides global system Reset (nRST) and Shutdown (SHDN) pins to the application board.
- The first pin is an output pin generated by the internal. Power Management Unit (MIC2800) in respect of power sequence timing. It can be forced externally in case of a system crash and must be connected as described in the example schematic below.
- The SHDN pin is an output pin and is managed by the software application. It switches the Main 3.3V Supply ON or OFF.
