3. Pinout and Package Information
The 10M16SAU169I7G uses the UBGA-169 (U169) package — a 169-ball ultra fine-pitch ball grid array measuring 11 mm × 11 mm with a 0.8 mm ball pitch. This compact BGA package is ideal for space-constrained designs while still providing 130 user I/O pins across multiple I/O banks.
The device organizes its I/O pins into multiple banks, each independently configurable for different voltage standards. This multi-bank architecture enables direct interfacing with 3.3V legacy devices and 1.8V/1.5V modern memory components on the same FPGA. Dedicated pins for JTAG programming (TCK, TDI, TDO, TMS), configuration, and power supply are allocated within the 169-ball footprint.

4. Architecture and Block Diagram
The Intel MAX 10 FPGA architecture integrates several key functional blocks into a single monolithic die:
- Logic Array Blocks (LABs): 1,000 LABs, each containing 16 adaptive logic elements with 4-input LUTs, registers, and carry chain logic.
- Embedded Memory: M9K memory blocks totaling 549 Kbit, configurable as single-port RAM, dual-port RAM, ROM, or FIFO buffers.
- DSP Blocks: 45 embedded 18×18 multipliers for efficient digital signal processing, supporting multiply-accumulate operations for filter implementations.
- Clock Management: 4 PLLs with up to 4 outputs each, supporting frequency synthesis, clock multiplication/division, and phase shifting.
- Analog-to-Digital Converter: Integrated dual ADC block with up to 17 analog input channels, 12-bit resolution at 1 MSPS — enabling true mixed-signal designs without external ADC chips.
- User Flash Memory: Non-volatile on-chip flash for storing configuration data, application code for Nios II soft processors, or user data.
- Instant-On Configuration: Internal flash configuration eliminates the need for external configuration devices, enabling power-on in milliseconds.

6. Frequently Asked Questions (FAQ)
What is the difference between the 10M16SAU169I7G and 10M16SAU169C8G?
The main differences are temperature range and speed grade. The I7G variant is rated for the industrial temperature range (-40°C to +100°C) with speed grade 7, while the C8G is rated for the commercial temperature range (0°C to +85°C) with speed grade 8 (slower). Choose the I7G for harsh environments, outdoor deployments, or industrial applications requiring extended temperature operation.
Does the 10M16SAU169I7G require an external configuration device?
No. The MAX 10 FPGA family features internal flash-based configuration storage, eliminating the need for an external configuration PROM or flash chip. The device stores up to two configuration images internally, supporting dual-boot and remote update capabilities. This results in instant-on operation (configuration in milliseconds at power-up) and reduced BOM cost.
What software tools are needed to program the 10M16SAU169I7G?
Intel's Quartus Prime Lite Edition (free download) fully supports the MAX 10 device family. It includes schematic entry, Verilog/VHDL design entry, synthesis, place-and-route, timing analysis, and the Programmer tool for JTAG-based device configuration. For embedded soft-processor designs, the Nios II Software Build Tools (included with Quartus Prime) are also available.
Can the 10M16SAU169I7G interface with DDR3 memory?
Yes. The MAX 10 family supports DDR3, DDR2, and LPDDR2 external memory interfaces. The 10M16 device can interface with DDR3 SDRAM at up to 300 MHz (600 Mbps data rate), enabling embedded systems with significant external memory bandwidth. Intel provides the External Memory Interface (EMIF) IP core in Quartus Prime for easy integration.
How many ADC channels does the 10M16SAU169I7G support?
The 10M16SAU169I7G integrates a dual ADC block with up to 17 analog input channels. Each ADC provides 12-bit resolution at up to 1 MSPS (mega samples per second). An internal temperature sensing diode is also available. This integrated ADC eliminates the need for external ADC chips in many mixed-signal applications such as power monitoring, sensor data acquisition, and system health management.
What is the UBGA-169 package and what are its advantages?
The UBGA-169 (Ultra Fine-Pitch Ball Grid Array, 169 balls) is an 11 mm × 11 mm surface-mount package with a 0.8 mm ball pitch. Its advantages include: (1) very small footprint for space-constrained PCB designs, (2) excellent thermal performance due to the BGA's large solder-ball contact area with the board, (3) shorter signal paths for better high-speed signal integrity, and (4) compatibility with standard SMT assembly processes (requires X-ray inspection for quality control).
