SOM Overview
Jacinto 7 System On Module
Features
According to Texas Instruments website, Jacinto 7 SOM has the following features:
- TDA4VM/DRA829V (J721 E) processor
- Optimized power solution (PMIC)
- DRAM, LPDDR4‐3733, 4GByte total memory, support inline ECC
- Octal‐SPI NOR flash, 512Mb memory (8bit)
- HyperFlash + HyerRAM, 512Mb flash memory + 256Mb RAM
Also, it is important to mention that TDA4VM and DRA829V processors heterogeneous architecture includes:
- A mix of fixed and floating-point DSP cores
- Arm® Cortex®-A72 cores
- Matrix math acceleration for machine learning
- Integrated ISP and vision processing acceleration
- 2D and 3D GPU cores
- H.264 encode/H.265 decode acceleration

Configuration
The switches SW1, SW2 and SW3 are called configuration switches and
Switch Name | Default Condition | Signal | Operation |
---|---|---|---|
SW1.1 | ON | LPDDR4_IO_SEL | Selects the I/O voltage level for LPDDR4:
‘0’ (OFF) = Selects 0.6 V I/O for LPDDR4X,‘1’ (ON) = Selects 1.1 V I/O for LPDDR4 |
SW1.1 | ON | LPDDR4_IO_SEL | Selects the I/O voltage level for LPDDR4:
‘0’ (OFF) = Selects 0.6 V I/O for LPDDR4X,‘1’ (ON) = Selects 1.1 V I/O for LPDDR4 |
SW1.1 | ON | LPDDR4_IO_SEL | Selects the I/O voltage level for LPDDR4:
